The Radiologic Evaluation of Pediatric Acute Abdomen; Results of Tertiary Referral Center

Purpose: In this study we aimed to evaluate the radiological examinations of the pediatric patients who were operated with initial diagnosis of acute abdomen. Methods: We retrospectively reviewed the clinical records and imaging findings of 252 children. All patients were evaluated by plain abdominal radiographs (PAX) and ultrasonography (US). Only 10 patients were examined using computed tomography (CT). The findings of the PAX, US and CT of each patient were determined from their detailed archive records according to their clinical diagnosis. Results: The most frequent pathology was appendicitis in our study whereas the other pathologies were invagination, ovarian torsion, the complications of Meckel’s diverticulum, gastrointestinal obstruction and tuboovarian abscess in decreasing frequency. PAXs were valuable in diagnosis of the patients with ileus. It has been showed that US was the most useful for patients with appendicitis and invagination. CT was performed only in 4% of our cases as an advanced diagnostic method. Conclusion: The pediatric patients with acute abdomen have been evaluated radiologically by PAX and US routinely and frequently. CT was performed as an advanced diagnostic method very rarely. CT would be utilized to a lower extent as a more advanced method of imaging in unsolved patient group, as US and PAX solve the pediatric acute abdominal pathologies in high percentages

Contribution of Kinetic Characteristics of Axillary Lymph Nodes to the Diagnosis in Breast Magnetic Resonance Imaging

Objective: To assess the contribution of kinetic characteristics in the discrimination of malignant-benign axillary lymph nodes. Material and Methods: One hundred fifty-five female patients were included in the study. Following magnetic resonance imaging (MRI) examinations post-processing applications were applied, dynamic curves were obtained from subtracted images. Types of dynamic curves were correlated with histopathological results in malignant cases or final clinical results in patients with no evidence of malignancy. Sensitivity, specificity, positive likehood ratio (+LHR), negative (-LHR) of dynamic curves characterizing the axillary lymph nodes were calculated.Results: A total of 178 lymph nodes greater than 8 mm were evaluated in 113 patients. Forty-six lymph nodes in 24 cases had malignant axillary involvement. 132 lymph nodes in 89 patients with benign diagnosis were included in the study. The sensitivity of type 3 curve as an indicator of malignancy was calculated as 89%. However the specificity, +LHR, -LHR were calculated as 14%, 1.04, 0.76 respectively. Conclusion: Since kinetic analysis of both benign and malignant axillary lymph nodes, rapid enhancement and washout (type 3) they cannot be used as a discriminator, unlike breast lesions. MRI, depending on the kinetic features of the axillary lymph nodes, is not high enough to be used in the clinical management of breast cancer patients

Does a correlation exist between radiological findings and pain or function in knee osteoarthritis? A cross-sectional analysis of the radiological findings obtained from two various conventional radiological techniques Di̇z osteoartri̇ti̇nde radyoloji̇k bulgularla aǧri veya fonksi̇yon arasinda i̇li̇şki̇ var midir? İki ayri konvansiyonel radyografik yöntem ile elde edilen radyolojik bulgulari deǧerlendiren kesitsel bir analiz

There have been concerns about the relation between radiological and clinical symptoms in knee osteoarthritis (OA). The aim of this study was to compare the Kellgren-Lawrence (K/L) grading, semiquantitave osteophyte score (SOS), the medial joint space score in supine anteroposterior (AP) film of the extended knees (SupMJS), the medial joint space score in AP film of standing knees in semiflexion (StMJS), with pain, range of motion (ROM) and function in patients with knee OA. In 37 patients with knee OA, pain was evaluated with visual analog scale, ROM with goniometry and the function with Lequesne functional index (LFI). Pain with motion was higher, but the active and passive flexion ranges were less in grade 4 K/L patients when compared with earlier grades. All radiological criterias except SupMJS were in significant positive correlation with only motion pain while all radiological parameters correlated negatively with active flexion ranges. No significant correlation was found for other pain types and LFI. In lineer regression analysis only SOS was observed to have relation with motion pain (Motion pain score=3.757+1.064x SOS). It seemed to be wise to obtain AP films of standing knees in semiflexed position and take care of StMJS together with K/L classification and SOS in order to predict the motion pain in patients with knee OA
