학위논문 (석사) -- 서울대학교 대학원 : 행정대학원 행정학과(정책학전공), 2020. 8. 최태현.본 연구에서는 주민청구조례안이 지방의회에서 조례로 결정되는데 미치는 요인을 알아보고자 2000년 1월부터 2019년 12월 말까지 전국 기초자치단체를 대상으로 청구된 총 206건의 주민청구조례안에 대한 실증분석을 진행하였다. 연구의 종속변수로 주민청구조례안의 가결과 주민청구조례안의 반영을 선정하였다. 각 종속변수에 영향을 미칠 것으로 예상되는 독립변수로 지방자치단체 내적 요인으로서 Almond & Powell과 Lowi의 정책유형을 혼합한 구성정책·배분정책·규제정책·상징정책의 네 가지 정책유형과 주민참여 요소로서 청원건수 및 지방선거투표율을, 지방자치단체 외적 요인으로서 정부 간 관계와 관련하여 재정적 요인으로서 재정자립도, 정치적 요인으로서 단체장·대통령 소속정당 일치 여부를 선정하였다. 통제변수로 청구환경적 요인으로서 사회·인구학적 요인에 해당하는 고령인구 비율, 남녀성비, 주민등록인구를 선정하였다. 각 종속변수에 따른 2개의 모형을 설계한 후 이에 미치는 영향요인을 식별하고자 이항로지스틱 회귀분석을 실시하였다. 로지스틱 회귀분석 결과는 다음과 같다. 지자체 내적 요인으로서 조례내용의 정책유형 중 배분정책과 주민참여를 대리하는 변수인 지방선거투표율은 두 모형 모두에서 통계적으로 유의미한 것으로 나타났다. 반면, 지자체 외적 요인에 해당하는 재정자립도 및 단체장·대통령 소속 정당일치여부, 청구환경적 요인으로서 남녀성비, 주민등록인구, 지자체 내적요인으로서 주민참여 요인에 해당하는 청원 건수는 두 모형 모두에서 유의미하지 않았다. 한편, 고령인구비율 변수는 두 모형에서 상반된 결과로 나타났다. 이러한 분석결과에 따른 본 연구의 의의는 다음과 같다. 첫째, 독립변수 선정과 관련하여 조례안의 내용을 Almond & Powell이 분류한 정책유형인 배분정책, 규제정책, 상징정책에 Lowi의 구성정책을 혼합하여 분석을 시도함으로써 기존 선행연구들에서 정책유형의 분류로서 다소 사용되지 않았던 정책유형의 종류를 변수로 선정하였다. 둘째, 조례제정에 영향을 미치는 요인에 관한 선행연구들에서는 주로 가결을 종속변수로 선정하였으나, 본 연구에서는 가결 뿐만 아니라 반영을 함께 고려하였다. 셋째, 주민청구조례안의 반영여부를 판단하기 위해 총 206건의 주민청구조례안 중 36건의 원안가결을 제외한 170건의 조례안들을 하나씩 추적해가며 검토하였다. 마지막으로, 이에 대한 판단을 하는 데 있어 자의성을 최대한 배제하기 위해서 해당 조례안과 관련된 업무를 담당하는 담당 공무원과의 통화, 인터넷 검색을 통한 신문기사·뉴스의 조사로부터 조례를 청구하였던 주민의 인터뷰, 지방의회홈페이지에서 제공되는 회의록, 자치법규정보시스템 홈페이지에서 제공되는 조례의 연혁 등을 모두 검토하며 종속변수 측정에 있어 타당도를 높이려 했다는 점에서 의의를 지닌다고 볼 수 있다. 실증분석 결과에 따라 본 연구는 다음과 같은 정책적 시사점을 제시하였다. 주민이 조례안을 청구할 때 지방정부나 지방의회가 주민에게 국선변호인을 선임해줄 수 있는 제도의 신설, 주민청구조례안에 대해 토의하고 협력할 수 있는 기초지방자치단체와 광역지방자치단체 간 전담 통로의 설치, 청구요건의 완화 및 청구절차의 간소화, 주민청구조례안의 건수를 증가시킬 수 있는 정책의 설계, 지방의회에서 배분정책 관련 내용의 조례안을 제정·개정·폐지할 때 주민을 참여하도록 하는 정책설계 등을 정책적 방안들로서 논의하였다. 이상과 같은 연구의 의의 및 정책적 시사점에도 불구하고 본 연구는 다음과 같은 한계점을 가지고 있다. 첫째, 조례제정및개폐청구제도가 1999년 8월에 도입되었으나 정착된 지 얼마 되지 않아 지방의회의원이 발의한 조례와 비교하였을 때 주민이 청구한 조례의 양 자체가 매우 적어 연구 주제의 본질적인 한계가 존재한다. 둘째, 종속변수 중 하나로서 반영을 선정하였는데, 해당 조례안의 반영 여부를 판단하는 데 있어 관련 업무를 담당하는 담당 공무원 조차도 반영여부에 대해 확실하게 답변하지 못하거나 인터넷 검색을 통한 신문기사·뉴스, 지방의회홈페이지에서 제공되는 회의록, 자치법규정보시스템 홈페이지에서 제공되는 조례의 연혁 등을 통해서도 판단하기 어려운 경우가 있었다는 점에서 다소 자의적일 수 있는 여지가 존재한다. 마지막으로, 정보공개청구를 통해 전국 기초자치단체로부터 확보한 주민청구조례안의 건수와 행정안전부 홈페이지에 게시된 자료에 공고된 건수가 불일치했을뿐만 아니라 조례안의 내용에 있어서도 행정안전부와 기초지방자치단체가 정보가 불일치 하는 경우도 있었으며, 오래된 자료의 경우 조례안의 내용에 대한 정보가 존재하지 않은 채 조례명만 남아 있어 이러한 사항에 해당하는 조례안들은제외한 채 실증분석을 진행하였다는 점에서 한계가 존재한다. 주민의 조례제정 및 개폐청구제도가 아직 정착되지 않은 만큼 본 연구는 시작 단계에 불과하다. 이후 끊임없는 보완을 통한 제도적 발전과 후속 연구가 진행되어야 할 것으로 생각된다.In this study, an empirical analysis was conducted on a total of 206 cases of resident petition cases requested to local governments across the country from January 2000 to the end of December 2019 to find out the factors that affect the decision of the local council. The Passing of the Residents' Petition and Reflection of the Residents' Petition were selected as the dependent variables of the study. The independent variables expected to affect each dependent variable are as follows: As internal factors of local governments, four types of policies were selected, including constitutional policy, distributive policy, regulatory policy and symbolic policy, which were mixed with the policy types of Almond & Powell and Lowi. In addition, the number of petitions and local election turnout were selected as factors for residents' participation. As an external factor for local governments, in relation to inter-governmental relations, the degree of financial independence as a financial factor and the unity of the heads of organizations and the parties belonging to the president as a political factor were selected. After designing two models for each dependent variable, a binary logistic regression method was applied to identify the factors affecting them. Logistic regression results are as follows: allocation policy among policy types of ordinance contents and voter turnout in local elections, a variable representing residents' participation, was statistically significant in both models. On the other hand, the degree of financial independence and whether the heads of organizations and the president's parties are in agreement were not significant in both models. The number of petitions that correspond to the resident participation factors, the gender ratio of men and women and the population of resident registration were also insignificant in both models. On the other hand, the elderly population ratio variable was found to be the opposite result in the two models. The significance of this study is as follows. First, in previous prior studies, the types of policy types that were not used as classification of policy types were selected as variables. Second, the preceding studies on factors affecting the enactment of the ordinance mainly selected the passing as a dependent variable, but in this study, not only 'passing' but also 'reflection' were considered. Third, 170 ordinances were reviewed one by one, excluding 36 original ones, out of a total of 206 proposals for the residents' petition to determine whether the ordinance was reflected. Finally, in order to exclude arbitrary interpretation as much as possible, it is meaningful in that it reviewed all the phone calls with the public official, interviews with residents who requested the ordinance from the investigation of newspaper articles through Internet search, minutes provided on the local council website, and the history of the ordinance provided on the website of the municipal ordinance information system, and improved the validity of the dependent variables. Based on the results of the empirical analysis, this study presented the following policy implications: the establishment of a system in which local governments or local councils can appoint public defenders to residents when residents request the ordinance; the establishment of a dedicated passageway between basic and metropolitan local governments that can cooperate with the residents' petition; relaxation of billing requirements and simplify billing procedures; the design of policies that can increase the number of cases in the residents' petition; policy design was discussed as policy measures to encourage residents to participate in the enactment, amendment or abolition of the ordinance related to the distribution policy by the local council. Despite the significance and policy implications of the study as above, this study has the following limitations: First, the amount of the ordinance requested by residents itself is very small compared to the ordinance proposed by local council members. Second, 'reflection' was selected as one of the dependent variables, and it may be somewhat arbitrary. Finally, the Ministry of Public Administration and Security and the local government did not agree on the contents of the ordinance, so the empirical analysis was conducted without the ordinance bill corresponding to these matters. As the Residents' Initiative Movement System has not yet been established, this study is only the beginning stage. It is thought that institutional development and follow-up research should be carried out through constant supplementation.제 1 장 서론 1 제 1 절 연구의 배경 및 목적 1 제 2 절 연구의 대상 및 방법 6 제 2 장 이론적 논의 및 선행연구 검토 9 제 1 절 로컬거버넌스와 주민조례제정개폐청구제도 10 1. 로컬거버넌스 10 1) 의의 10 2) 로컬거버넌스를 바라보는 관점 12 2. 주민조례제정개폐청구제도 14 1) 의의 14 2) 기능 15 3) 절차 18 제 2 절 정책결정의 영향요인 24 1. 정책결정요인론 24 2. 정책유형과 주민참여: 지자체 내적 요인 26 1) 정책의 개념 27 2) 정책유형에 대한 학자들의 다양한 분류 28 3) 주민참여 33 3. 정부 간 관계: 지자체 외적 요인 36 1) 정부 간 관계의 개념과 유형 37 2) 우리나라의 정부 간 관계의 특성 39 제 3 절 선행연구 42 1. 지방정부 정책결정요인에 관한 선행연구 42 2. 조례제정 결정요인에 관한 선행연구 45 1) 일반 조례를 대상으로 한 선행연구 45 2) 주민청구조례 관련 선행연구 47 3. 지방정부의 정책유형 관련 선행연구 48 제 4 절 요약 및 시사점 51 제 3 장 연구의 설계 및 분석방법 55 제 1 절 연구의 분석틀 및 연구가설 55 1. 연구의 분석틀 55 2. 연구가설 57 1) 지자체 내적 요인: 정책유형과 주민참여 58 2) 지자체 외적 요인: 재정요인과 정치요인 62 3. 가설검증을 위한 분석모형 64 제 2 절 주요 변수의 선정과 측정 방법 66 1. 종속변수 66 2. 독립변수 68 3. 통제변수 72 제 3 절 연구방법 및 자료의 수집 75 1. 연구방법 75 2. 자료수집 78 제 4 장 분석결과 83 제 1 절 기술통계분석 83 1. 종속변수 기술통계분석 83 2. 독립변수 기술통계분석 87 1) 지자체 내적 요인: 정책유형과 주민참여 87 2) 지자체 외적 요인: 재정요인과 정치요인 88 3. 통제변수 기술통계분석 89 제 2 절 상관관계분석 90 1. 변수 간 상관관계 90 2. 비율변수 간 상관관계 92 제 3 절 이항 로지스틱 회귀분석 95 1. 이항 로지스틱 회귀분석 모형의 적합도 검정 95 2. 이항 로지스틱 회귀분석 결과 96 1) 모형 1: 종속변수가 '가결'인 경우 97 2) 모형 2: 종속변수가 '반영'인 경우 99 3. 가설 검증과 결과의 해석 101 제 5 장 결론 107 제 1 절 연구결과의 요약 107 제 2 절 연구결과의 의의 110 제 3 절 정책적 시사점 112 제 4 절 연구의 한계 115 참고문헌 117 Abstract 127Maste

Reliability of Breast Ultrasound BI-RADS Final Assessment in Mammographically Negative Patients with Nipple Discharge and Radiologic Predictors of Malignancy

PURPOSE: The purpose of this study was to retrospectively investigate the reliability of breast ultrasound (US) Breast Imaging Reporting and Data System (BI-RADS) final assessment in mammographically negative patients with pathologic nipple discharge, and to determine the clinical and ultrasonographic variables associated with malignancy in this group of patients. METHODS: A total of 65 patients with 67 mammographically negative breast lesions that were pathologically confirmed through US-guided biopsy were included. RESULTS: Of the 53 BI-RADS category 4 and 5 lesions, eight (15.1%) were malignant (six ductal carcinomas in situ, one invasive ductal carcinoma, and one solid papillary carcinoma). There was no malignancy among the remaining 14 category 3 lesions. Malignant lesions more frequently displayed a round or irregular shape (75.0%, 6/8; p=0.030) and nonparallel orientation (33.3%, 4/12; p=0.029) compared to the benign lesions. The increase in the BI-RADS category corresponded with a rise in the malignancy rate (p=0.004). CONCLUSION: The BI-RADS lexicon and final assessment of breast US reliably detect and characterize malignancy in mammographically negative patients with pathologic nipple discharge.ope

육안적 혈뇨를 주소로 내원한 환아의 포도상의 윌름스 종양: 증례 보고

We report a unique case of botryoid Wilms' tumor with its characteristic imaging findings in a 5-month-old boy presenting with gross hematuria. In our case, ultrasonography revealed lobulated hyperechoic lesions filling the pelvicalyceal system without parenchymal invasion, mimicking a blood clot. However, magnetic resonance imaging (MRI) demonstrated the exact extent of the lesion with diffusion restriction and delayed enhancement suggestive of a tumor. Despite their rarity, botryoid Wilms' tumors should be included in the differential diagnosis of lobulatedope

Contrast-Enhanced CT with Knowledge-Based Iterative Model Reconstruction for the Evaluation of Parotid Gland Tumors: A Feasibility Study

Objective: The purpose of this study was to determine the diagnostic utility of low-dose CT with knowledge-based iterative model reconstruction (IMR) for the evaluation of parotid gland tumors. Materials and Methods: This prospective study included 42 consecutive patients who had undergone low-dose contrast-enhanced CT for the evaluation of suspected parotid gland tumors. Prior or subsequent non-low-dose CT scans within 12 months were available in 10 of the participants. Background noise (BN), signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) were compared between non-low-dose CT images and images generated using filtered back projection (FBP), hybrid iterative reconstruction (iDose4; Philips Healthcare), and knowledge-based IMR. Subjective image quality was rated by two radiologists using five-point grading scales to assess the overall image quality, delineation of lesion contour, image sharpness, and noise. Results: With the IMR algorithm, background noise (IMR, 4.24 ± 3.77; iDose4, 8.77 ± 3.85; FBP, 11.73 ± 4.06; p = 0.037 [IMR vs. iDose4] and p < 0.001 [IMR vs. FBP]) was significantly lower and SNR (IMR, 23.93 ± 7.49; iDose4, 10.20 ± 3.29; FBP, 7.33 ± 2.03; p = 0.011 [IMR vs. iDose4] and p < 0.001 [IMR vs. FBP]) was significantly higher compared with the other two algorithms. The CNR was also significantly higher with the IMR compared with the FBP (25.76 ± 11.88 vs. 9.02 ± 3.18, p < 0.001). There was no significant difference in BN, SNR, and CNR between low-dose CT with the IMR algorithm and non-low-dose CT. Subjective image analysis revealed that IMR-generated low-dose CT images showed significantly better overall image quality and delineation of lesion contour with lesser noise, compared with those generated using FBP by both reviewers 1 and 2 (4 vs. 3; 4 vs. 3; and 3-4 vs. 2; p < 0.05 for all pairs), although there was no significant difference in subjective image quality scores between IMR-generated low-dose CT and non-low-dose CT images. Conclusion: Iterative model reconstruction-generated low-dose CT is an alternative to standard non-low-dose CT without significantly affecting image quality for the evaluation of parotid gland tumors.ope

Breast Cancer Arising Adjacent to an Involuting Fibroadenoma: Serial Changes in Radiologic Features

Fibroadenoma is a common benign breast lesion and its malignant transformation is rare. There have been several case reports and studies that retrospectively reviewed breast cancers that arose within fibroadenomas; however, none of these studies reported serial changes in radiologic features of the cancer, including findings from mammography and ultrasound (US). We report a case of breast cancer arising adjacent to an involuting fibro adenoma in a 39-year-old woman who was undergoing serial follow-up after her fibroadenoma was diagnosed. Seven years after her diagnosis, the lesion showed evidence of coarse calcifications, a typical sign of involution. Four years later, US revealed a newly developed hypoechoic lesion with irregular margins and peripherally located calcifications adjacent to the fibroadenoma. A core biopsy was performed, and histopathological examination resulted in a diagnosis of invasive ductal carcinoma. When new suspicious features are observed in a fibroadenoma, radiologists should raise the concern for breast cancer and proceed with diagnosis and treatment accordinglyope

Prognostic significance of preoperative CT findings in patients with advanced gastric cancer who underwent curative gastrectomy

BACKGROUND: Preoperative therapy has gained wide interest in advanced gastric cancer patients due to its potential advantages of improved disease control. Selection of high risk patients based on preoperative staging is crucial to choose the candidates for neoadjuvant therapy. METHODS: Our institutional review board approved this retrospective study and waived the requirement for patient consent. We searched 394 advanced gastric cancer patients (pT2-4) who underwent curative resection in 2010 without neoadjuvant therapies. Two abdominal radiologists independently reviewed the preoperative CT including tumor depth on CT (CT-tumor depth), which was categorized as follows: intramural, minimal extramural(<1mm), spiculated extramural(≥1mm) and nodular extramural infiltration. The impact of clinicoradiologic factors on disease recurrence and disease free survival (DFS) was evaluated. Recursive partitioning analysis was performed to suggest prediction models for recurrence. RESULTS: Of total 394 patients, 86 patients (21.8%) experienced recurrence. Spiculated (≥1mm) and nodular extramural tumor infiltration and CT size of 5-10cm were independent predictors of disease recurrence and significantly associated with worse DFS. Lymph node involvement on CT was not significantly associated with patient outcome. Among patients with same pT4a stage, the recurrence rate rises and DFS gets worse as the extramural tumor infiltration progresses (P < 0.001). The prediction model for recurrence revealed that size and CT-tumor depth were the two major discriminating factors. CONCLUSION: CT-tumor depth and size could be used as independent predictors for prognosis. Preoperative CT can be used for prognostic stratification to select high risk patients for whom neoadjuvant therapies might be considered.ope

Evaluation of glymphatic system activity using diffusion tensor image analysis along the perivascular space and amyloid PET in older adults with objectively normal cognition: a preliminary study

Objectives: Dementia is a clinical syndrome caused by multiple etiologies, usually manifests with progressive and diffuse brain dysfunction. The activity of the human glymphatic system was evaluated in cases of dementia by the diffusion tensor image analysis along the perivascular space (DTI-ALPS). Methods: We recruited 28 healthy subjects and 77 patients, including 38 with Alzheimer's disease (AD),18 with mild cognitive impairment (MCI), 28 with normal controls (NC) and 21 with vascular cognitive impairment (VCI). All participants underwent DTI scanning. Diffusivities in the X, Y and Z axes were obtained in the lateral ventricle body plane of all subjects. We assessed the diffusivity along the perivascular spaces, as well as projection fibers and association fibers, respectively, in order to acquire an DTI-ALPS-index and correlated them with mini mental state examination (MMSE) and montreal cognitive assessment (MOCA) scores using partial correlation which the influence of age was controlled. Results: The AD, MCI, and VCI patients showed significantly lower DTI-ALPS-index (p < 0.001) compared to the NC. Besides, the VCI group had significantly higher DTI-ALPS-index than the AD group (p = 0.007). There was a significant positive correlation between DTI-ALPS-index and MMSE and MOCA scores (the effect of age was controlled), showing that lower water diffusivity along the perivascular spaces associated with dementia.The higher Dzassoc led to the reduced DTI-ALPS-index in VCI, while lower Dxassoc contributed to the decrease of DTI-ALPS-index in AD. Conclusion: The evaluation of DTI-ALPS demonstrates impairment of the glymphatic system in dementia patients by decreased DTI-ALPS-index. Different from AD, the VCI patients show glymphatic drainage disorder rather than glymphatic system impairment. Advances in knowledge: This article comprehensively covers several types of dementia and performs the comparison of VCI, AD and MCI in glymphatic system dysfunction.ope

Quality of Radiomics Research on Brain Metastasis: A Roadmap to Promote Clinical Translation

Objective: Our study aimed to evaluate the quality of radiomics studies on brain metastases based on the radiomics quality score (RQS), Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) checklist, and the Image Biomarker Standardization Initiative (IBSI) guidelines. Materials and methods: PubMed MEDLINE, and EMBASE were searched for articles on radiomics for evaluating brain metastases, published until February 2021. Of the 572 articles, 29 relevant original research articles were included and evaluated according to the RQS, TRIPOD checklist, and IBSI guidelines. Results: External validation was performed in only three studies (10.3%). The median RQS was 3.0 (range, -6 to 12), with a low basic adherence rate of 50.0%. The adherence rate was low in comparison to the "gold standard" (10.3%), stating the potential clinical utility (10.3%), performing the cut-off analysis (3.4%), reporting calibration statistics (6.9%), and providing open science and data (3.4%). None of the studies involved test-retest or phantom studies, prospective studies, or cost-effectiveness analyses. The overall rate of adherence to the TRIPOD checklist was 60.3% and low for reporting title (3.4%), blind assessment of outcome (0%), description of the handling of missing data (0%), and presentation of the full prediction model (0%). The majority of studies lacked pre-processing steps, with bias-field correction, isovoxel resampling, skull stripping, and gray-level discretization performed in only six (20.7%), nine (31.0%), four (3.8%), and four (13.8%) studies, respectively. Conclusion: The overall scientific and reporting quality of radiomics studies on brain metastases published during the study period was insufficient. Radiomics studies should adhere to the RQS, TRIPOD, and IBSI guidelines to facilitate the translation of radiomics into the clinical field.ope

An interpretable radiomics model to select patients for radiotherapy after surgery for WHO grade 2 meningiomas

Objectives: This study investigated whether radiomic features can improve the prediction accuracy for tumor recurrence over clinicopathological features and if these features can be used to identify high-risk patients requiring adjuvant radiotherapy (ART) in WHO grade 2 meningiomas. Methods: Preoperative magnetic resonance imaging (MRI) of 155 grade 2 meningioma patients with a median follow-up of 63.8 months were included and allocated to training (n = 92) and test sets (n = 63). After radiomic feature extraction (n = 200), least absolute shrinkage and selection operator feature selection with logistic regression classifier was performed to develop two models: (1) a clinicopathological model and (2) a combined clinicopathological and radiomic model. The probability of recurrence using the combined model was analyzed to identify candidates for ART. Results: The combined clinicopathological and radiomics model exhibited superior performance for the prediction of recurrence compared with the clinicopathological model in the training set (area under the curve [AUC] 0.78 vs. 0.67, P = 0.042), which was also validated in the test set (AUC 0.77 vs. 0.61, P = 0.192). In patients with a high probability of recurrence by the combined model, the 5-year progression-free survival was significantly improved with ART (92% vs. 57%, P = 0.024), and the median time to recurrence was longer (54 vs. 17 months after surgery). Conclusions: Radiomics significantly contributes added value in predicting recurrence when integrated with the clinicopathological features in patients with grade 2 meningiomas. Furthermore, the combined model can be applied to identify high-risk patients who require ART.ope

Contrast-Enhanced High-Resolution Intracranial Vessel Wall MRI with Compressed Sensing: Comparison with Conventional T1 Volumetric Isotropic Turbo Spin Echo Acquisition Sequence

Objective: Compressed sensing (CS) has gained wide interest since it accelerates MRI acquisition. We aimed to compare the 3D post-contrast T1-weighted volumetric isotropic turbo spin echo acquisition (VISTA) with CS (VISTA-CS) and without CS (VISTA-nonCS) in intracranial vessel wall MRIs (VW-MRI). Materials and methods: From April 2017 to July 2018, 72 patients who underwent VW-MRI, including both VISTA-CS and VISTA-nonCS, were retrospectively enrolled. Wall and lumen volumes, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) were measured from normal and lesion sites. Two neuroradiologists independently evaluated overall image quality and degree of normal and lesion wall delineation with a four-point scale (scores ≥ 3 defined as acceptable). Results: Scan coverage was increased in VISTA-CS to cover both anterior and posterior circulations with a slightly shorter scan time compared to VISTA-nonCS (approximately 7 minutes vs. 8 minutes). Wall and lumen volumes were not significantly different with VISTA-CS or VISTA-nonCS (interclass correlation coefficient = 0.964-0.997). SNR was or trended towards significantly higher values in VISTA-CS than in VISTA-nonCS. At normal sites, CNR was not significantly different between two sequences (p = 0.907), whereas VISTA-CS provided lower CNR in lesion sites compared with VISTA-nonCS (p = 0.003). Subjective wall delineation was superior with VISTA-nonCS than with VISTA-CS (p = 0.019), although overall image quality did not differ (p = 0.297). The proportions of images with acceptable quality were not significantly different between VISTA-CS (83.3-97.8%) and VISTA-nonCS (75-100%). Conclusion: CS may be useful for intracranial VW-MRI as it allows for larger scan coverage with slightly shorter scan time without compromising image quality.ope
