Department of Radiology and Medical Imaging, Departament of Plastic and Reconstructive Surgery University of Medicine and Pharmacy of Craiova, Craiova, Romania, The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Background: Breast cancer is the most common form of cancer worldwide, with a high mortality rate. Romania ranks first in Europe in the incidence and mortality of breast cancer. Content: The presentation highlights the principles of management of breast cancer in advanced pregnancy. The case of a 39-year-old woman, 32 weeks pregnant, taken to the emergency department for painful uterine contractions is also presented. General clinical examination revealed a palpable breast mass in the right breast with perilesional skin erythema and a bloody nipple discharge, raising the suspicion of Paget’s disease of the breast. The breast ultrasound (US) described a hypoechogenic mass between the inferior breast quadrants. The diagnosis of invasive ductal carcinoma was sustained by elastography and established after ultrasound-guided breast biopsy. The caesarean delivery was performed (33-34 weeks) followed by bilateral ovariectomy. Subsequently, after neoadjuvant chemotherapy, the patient underwent Madden modified radical mastectomy and continued with chemotherapy and radiotherapy. Medical imaging provided valuable information for tumor staging and re-staging, guiding the treatment strategy as well as subsequent follow-up. Conclusions: This case underlines the limited treatment options in pregnant women with oncological pathology and highlights the fine line between maternal health and child safety for ensuring the best outcome

Quantitative evaluation of fatty liver using spectroscopic sequence – correlation between Magnetic Resonance Spectroscopy and histopathology

Department of Radiology and Medical Imaging, University of Medicine and Pharmacy of Craiova, Craiova, Romania, The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Introduction: La stéatose hépatique entraîne l’accumulation des lipides dans les hépatocytes. La tomographie computerisée (CT) et l’échographie (US) peuvent évaluer qualitativement la graisse du foie. La technique d’imagerie la plus précise en termes de quantification de la stéatose hépatique est la Spectroscopie par Résonance Magnétique (MRS). L’objectif de l’étude était de valider le rôle de MRS 3T dans l’évaluation quantitative de la stéatose hépatique. Matériel et méthodes: Le foie de 33 patients a été évalué qualitativement par des tests de laboratoire et d’échographie. Tous les patients ont été étudiés avec une 3T haute résolution IRM, constituée de séquences en phase, déphasées et de séquences spécifiques pour la steatose en T1 pondérées, ainsi que des séquences en T2 pondérées et de séquences de spectroscopie. L’évaluation qualitative a été réalisée en utilisant la fraction de graisse calculée manuellement après l’analyse par spectroscopie. La stéatose a été classée 0 = jusqu’à 10%, grade 1 = 10-33%, grade 2 = 34-66%, grade 3 = ≥67%. La biopsie hépatique a été réalisée chez des patients opérés pour différentes pathologies. Résultats: Limitée par un petit nombre de patients et par les manoeuvres chirurgicales invasives de la biopsie hépatique, l’étude montre que cinq patients présentaient une stéatose classée en grade 0, treize – en grade 1, six – en grade 2 et un – en grade 3, offrant une bonne corrélation entre MRS et histopathologie. Conclusions: En dépit d’être une étude pilote, nous pouvons conclure que MRS est une technique non invasive efficace qui peut être extrêmement utile dans le diagnostic et la quantification de la stéatose hépatique.Background: Hepatic steatosis results in the accumulation of lipids within hepatocytes. Computed Tomography (CT) and Ultrasound (US) can qualitatively assess liver fat. The most accurate imaging technique in terms of quantifying hepatic steatosis is Magnetic Resonance Spectroscopy (MRS). The study aimed to validate the role of 3T MRS in quantitative assessment of liver steatosis. Material and methods: The liver of 33 patients was qualitatively assessed through lab and ultrasound tests. All patients were investigated with a 3T high resolution MRI consisting of T1 weighted sequences with in-phase, out-of-phase and fat specific phases and also T2 weighted and spectroscopy sequences. The qualitative assessment was carried out using the fat fraction calculated manually after spectroscopy computer analysis. The steatosis was graded as grade 0 = up to 10%, grade 1 = 10-33%, grade 2 = 34-66%, grade 3 = ≥ 67%. Liver biopsy was performed in patients who underwent surgery for different pathologies. Results: Limited by a small number of patients and surgical invasiveness of liver biopsy, the study shows that five patients had grade 0 steatosis, thirteen had grade 1, six patients – grade 2 and one patient – grade 3, offering a good correlation between MRS and histopathology. Conclusions: Despite being a pilot study, we can conclude that MRS is an effective noninvasive technique that can be extremely useful in diagnosing and quantifying hepatic steatosis

A rare case of extrahepatic cholangiocarcinoma – a multidisciplinary approach

Department of Radiology and Medical Imaging, Department of Rheumatology, Departament of Gastroenterology, University of Medicine and Pharmacy of Craiova, Craiova, Romania, The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Background: Bile duct carcinoma is an extremely aggressive and rare primary hepatobiliary malignancy affecting nearly 1-2/100,000 people in most countries in Europe. Biliary tract malignancies located in the distal third of the common bile duct (CBD) account for approximately 17-18% of all cholangiocarcinomas. This report aims to provide a step-by-step evaluation of a rare case of cholangiocarcinoma. Content: The current report focuses on a 65-year-old male patient who was presented to the emergency department with signs and symptoms suggestive for a biliary tract obstruction. An intense cooperation between multiple departments was required in order to perform a complete and accurate evaluation of the patient. Initially, the patient underwent an abdominal Ultrasonography (US), followed by an abdominal and pelvic Computed Tomography (CT), which revealed an intraductal tumor affecting the distal CBD. Furthermore, the patient underwent an endoscopic retrograde cholangiopancreatography (ERCP) in order to provide tissue samples and to perform a dilatation of the CBD in the affected area. The histopathology report confirmed the malignant nature of the lesion describing it as an adenocarcinoma. The surgeons performed a pancreaticoduodenectomy (Whipple procedure), managing to achieve negative tumor resection margins. However, the patient developed several complications that required multiple surgical reinterventions. Conclusions: This report presents a fully investigated less common type of cholangiocarcinoma, highlighting the principles of diagnosis and management as well as of a multidisciplinary approach in such patients

Role of gadoxetic-acid enhanced 3T MRI and diffusion in liver nodules diagnosis

Department of Radiology and Medical Imaging, University of Medicine and Pharmacy of Craiova, Craiova, Romania, The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Introduction: La capacité multiparamétrique et l’imagerie par résonance magnétique (IRM) 3T à haute résolution jouent un rôle clé dans la caractérisation non invasive des lésions hépatiques focales (LHF). Certaines LHF ont des caractéristiques atypiques. De nouvelles techniques telles que les séquences à diffusion pondérée et les agents de contraste spécifiques aux hépatocytes sont actuellement utilisées en pratique clinique pour améliorer la détection et la caractérisation des LHF. L’étude visait à valider un protocole d’imagerie hépatique de haute qualité en utilisant une IRM à haute résolution combinée à un milieu de contraste spécifique à la diffusion et à l’hépatocyte pour le diagnostic de la LHF. Matériel et méthodes: 110 patients hépatiques ont été étudiés en utilisant une IRM à haute résolution de 3T (Phillips Ingenia) en utilisant une bobine de matrice en phase de corps. Le protocole inclue les séquences Dixon-all T1, T2, SPAIR et de diffusion. L’IRM améliorée a supposé l’utilisation des séquences Dixon-T1 de l’acide gadoxétique (PRIMOVIST), y compris la phase hépatobiliaire à 20 minutes et 30 minutes. Résultats: 65 patients ont été diagnostiqués avec précision des lésions bénignes, y compris les hémangiomes, les kystes, l’hyperplasie nodulaire focale et les adénomes. Parmi 45 lésions malignes, nous avons trouvé des métastases, un carcinome hépatocellulaire (CHC) et une pseudotumeur inflammatoire. Les lésions ont été suivies ou une pathologie a été obtenue. Conclusions: L’IRM est capable de fournir des informations diagnostiques complètes et très précises, avec l’avantage supplémentaire de l’absence de rayonnements ionisants nocifs. Un protocole IRM de haute qualité pour le foie est également nécessaire pour établir un diagnostic correct.Background: The multiparametric ability and high-resolution 3T magnetic resonance imaging (MRI) plays a key role in non-invasive characterization of focal liver lesions (FLL). Some FLL have atypical features. New techniques such as diffusion-weighted sequences and hepatocyte-specific contrast agents are being currently used in clinical practice improving the detection and characterization of FLL. The study aimed to validate a high-quality hepatic imaging protocol using high-resolution MRI combined with diffusion and hepatocyte-specific contrast media for FLL diagnosis. Material and methods: 110 patients were liver investigated using a 3T high-resolution MRI (Phillips Ingenia) using body-phase array coil. The protocol included Dixon-all T1, T2, SPAIR and diffusion sequences. The enhanced MRI assumed the use of gadoxetic-acid (PRIMOVIST) Dixon-T1 sequences, including the hepatobiliary phase at 20 minutes and 30 minutes. Results: 65 patients were accurately diagnosed with benign lesions, including hemangiomas, cysts, focal nodular hyperplasia and adenomas. Among 45 malignant lesions we found metastasis, hepatocellular carcinoma (HCC) and one inflammatory pseudotumor. The lesions were followed-up or pathology was obtained. Conclusions: MRI is able to provide comprehensive and highly accurate diagnostic information, with the additional advantage of lack of harmful ionizing radiation. Also a high-quality liver MRI protocol is needed in order to establish a correct diagnosis

The role of ultrasound in the prognosis of adverse perinatal outcome in fetuses with intrauterine growth restriction

University of Medicine and Pharmacy of Craiova, County Clinical Emergency Hospital of Craiova, Craiova, Romania, The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Background: Doppler ultrasound may indicate poor fetal prognosis by detecting abnormal blood flow waveforms. The study aimed to evaluate the Doppler ultrasound assessment on umbilical artery (UA) and middle cerebral artery (MCA) as a predictive marker of perinatal outcome in fetuses with intrauterine growth restriction (IUGR). Material and methods: A total of 126 IUGR pregnancies with a birth weight <10 percentiles were ultrasonographically evaluated. Doppler velocity in UA and MCA, was performed at 30.6-32.6 weeks of pregnancy. We considered adverse perinatal outcome: Apgar score ≤7 to 1 and 5 minutes, admission to the Department of Neonatal Intensive Care (NICU), gestational age <37 weeks at birth. Results: In the abnormal Doppler group, the newborns weight was 7±1.51 percentile, Doppler anomaly (absent/reversed end diastolic flow, UA-PI>95 percentiles, cerebro-placental ratio <1) determined the Apgar score of 6±0.75/1 minute and 7±0.64/5 minutes, a gestational age at birth of 36.2±1.01 weeks (premature birth), an admission to the NICU of 30.15% for neonates. Comparatively, in the normal Doppler group, the newborns weight was 9±1.03 percentile, the Apgar score was 8±0.95/1 minute and 9±0.76/5 minutes, the gestational age at birth was 37.4±0.99 weeks and admission to the NICU was required in only 12.69% of neonates of this group. Conclusions: Doppler antenatal monitoring may be a useful marker in the prognosis of perinatal evolution in fetuses with severe growth restriction

Differential diagnosis of breast lesions using ultrasound elastography

Context: The recent introduction of elastography has increased the specificity of USG and enabled early diagnosis of breast cancer. Quantitative elastography, especially with strain ratio (SR) index, improves diagnostic accuracy and decreased number of biopsies. Aims: The purpose of this study was to assess the role of USG elastography in the differential diagnosis of breast lesions. Settings and Design: This prospective study was conducted in the University of Medicine and Pharmacy Research Centre of Craiova. Materials and Methods: Fifty-eight patients diagnosed with breast lesions between January 2009 and January 2010 were included in this prospective study. All the patients were examined in the supine position, and the B-mode USG image was displayed alongside the elastography strain image. For obtaining the elastography images we used a EUS Hitachi EUB 8500 ultrasound system with a 6.5-MHz linear probe. The elastography strain images were scored according to the Tsukuba elasticity score. Statistical Analysis: We performed receiver operator characteristic (ROC) analysis for assessment of the role of USG elastography in the diagnosis of breast lesions. Results: We obtained a sensitivity of 86.7% and a specificity of 92.9% for elasticity score and a sensitivity of 93.3% and a specificity of 92.9% for SR (when a cutoff point of 3.67 was used). There was very good correlation between SR and elasticity score (Spearman coefficient of 0.911). Conclusions: Elastography is a fast, simple method that can complement conventional USG examination. This method has the lowest cost/efficiency ratio and it is also the most noninvasive and accessible imaging method, with an accuracy comparable to MRI

Radioimaging aspects in knee degenerative pathology

Department of Radiology and Medical Imaging, University of Medicine and Pharmacy of Craiova, Craiova, Romania, The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Background: Gonarthrosis represents one of the most frequent knee conditions, most commonly found in the 5th-6th life decades and not only, mainly in women, being the main cause of motoric disability in Europe, with a high impact on the social and economic status. The aim of the presentation is to aid the interdisciplinary team in interconnecting the imaging and clinical diagnosis of the osteo-articular system pathology. Content: The presentation reviews the radioimaging aspects of knee degenerative pathology. The imaging findings of a 35-year-old patient, known with right femur-coxal congenital subluxation, secondary left gonarthrosis and motoric disability are also presented as an illustration. The imaging technique included the pangonogram (hip-knee-ankle), which is an x-ray of the entire lower limb in orthostatism. The pangonogram allowed us to measure the hip-knee-ankle (HKA) angle, the internal mechanic alpha-femur angle, the Calton index – kneecap height, the beta – internal mechanic tibial angle and the gamma angle – tibial chute. Based on the imaging technique, there were highlighted changes in the bone structure of the left femural head, with a suspicious aspect of an aseptic necrosis, an internally curved tibia and peroneum on the left and secondary left gonarthrosis. The patient was admitted to the Orthopedics Department and underwent the necessary measurements for receiving a personalized knee prosthesis. Conclusions: This presentation highlights the challenging presentations of gonarthrosis and the modern techniques of diagnosis and treatment

Tumor Area Highlighting Using T2WI, ADC Map, and DWI Sequence Fusion on bpMRI Images for Better Prostate Cancer Diagnosis

Prostate cancer is the second most common cancer in men worldwide. The results obtained in magnetic resonance imaging examinations are used to decide the indication, type, and location of a prostate biopsy and contribute information about the characterization or aggressiveness of detected cancers, including tumor progression over time. This study proposes a method to highlight prostate lesions with a high and very high risk of being malignant by overlaying a T2-weighted image, apparent diffusion coefficient map, and diffusion-weighted image sequences using 204 pairs of slices from 80 examined patients. It was reviewed by two radiologists who segmented suspicious lesions and labeled them according to the prostate imaging-reporting and data system (PI-RADS) score. Both radiologists found the algorithm to be useful as a “first opinion”, and they gave an average score on the quality of the highlight of 9.2 and 9.3, with an agreement of 0.96

Computer-Aided Diagnosis of Pulmonary Nodules in Rheumatoid Arthritis

(1) Background: Rheumatoid arthritis (RA) is considered a systemic inflammatory pathology characterized by symmetric polyarthritis associated with extra-articular manifestations, such as lung disease. The purpose of the present study is to use CAD in the detection of rheumatoid pulmonary nodules. In addition, we aim to identify the characteristics and associations between clinical, laboratory and imaging data in patients with rheumatoid arthritis and lung nodules. (2) Methods: The study included a number of 42 patients diagnosed with rheumatoid arthritis according to the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) criteria, examined from January 2017 to November 2022 in the Departments of Rheumatology and Radiology and Medical Imaging of the University of Medicine and Pharmacy of Craiova. Medical records were reviewed. A retrospective blinded review of CT for biopsy-proven pulmonary nodules in RA using Veolity LungCAD software was performed (MeVis Medical Solutions AG, Bremen, Germany). Imaging was also reviewed by a senior radiologist. (3) Results: The interobserver agreement proved to be moderate (&kappa; = 0.478) for the overall examined cases. CAD interpretation resulted in false positive results in the case of 12 lung nodules, whereas false negative results were reported in the case of 8 lung nodules. The mean time it took for the detection of lung nodules using CAD was 4.2 min per patient, whereas the detection of lung nodules by the radiologist was 8.1 min per patient. This resulted in a faster interpretation of lung CT scans, almost reducing the detection time by half (p &lt; 0.001). (4) Conclusions: The CAD software is useful in identifying lung nodules, in shortening the interpretation time of the CT examination and also in aiding the radiologist in better assessing all the pulmonary lung nodules. However, the CAD software cannot replace the human eye yet due to the relative high rate of false positive and false negative results
