Background: The radiographic urethrography is an invasive , time consuming procedure and due to risk of radiation exposure can’t be repeated when required, further it has failed to demonstrate periurethral abnormality as a cause of urethral lesion. Where as sonourethrography is a noninvasive, painless, cheap, quick, easy to perform and without radiation exposure and provide detail visualization of mucosal and periurethral soft tissue. Objectives: To establish the accuracy of sonourethrography in detecting urethral lesions. Materials and Methods: Study was conducted as single blind prospective study to compare the radiographic urethrography (RGU/MCU) and sonourethragraphy and to established their role and accuracy in evaluation of urethral abnormalities. The findings and results of radiographic urethrography and sonourethrography were correlated and considering radiographic urethrography as gold standard, accuracy of sonourethrography in diagnosis of urethral lesions were analyzed. Result: Total of 27 patients were included in the study. RGU showed normal anterior (penile and bulbar) urethra in 12 out of 27 cases while among these only 9 were normal on sonourethrography. The length of stricture measured on sonourethrography was slightly more than as measured on RGU. Periurethral causes for urethral abnormality were completely identified on sonourethrography while they were not identified on RGU. Conclusion: Radiographic urethrography though gold standard in evaluating urethral abnormalities, sonourethrography is equally accurate (sensitivity 100%) in the diagnosis of urethral lesions. Sonourethrography has advantage in better evaluating mucosal and periurethral abnormalities as cause of urethral lesions. Further sonourethrography is more accurate in measurement of stricture length and it is cheap, safe and does not provide any kind of radiation to the patients in gonad areas.

AbstractBone and soft tissue tumors are a largely heterogeneous group of tumors. Biopsy of musculoskeletal (MSK) tumors is sometimes a challenging procedure. Although the open biopsy is still considered the gold standard for the biopsy of MSK lesions, core needle biopsy can replace it in most cases, with similar accuracy and a low complication rate. The biopsy should be performed in a tertiary sarcoma center where the multidisciplinary team consists of at minimum a tumor surgeon, an MSK pathologist, and an MSK radiologist who can assess all steps of the procedure. Several factors can influence the success of the biopsy including the lesion characteristics, the equipment, and the method used for the procedure. This review highlights some of the important aspects regarding the biopsy of the MSK tumors, with special attention to imaging a guided core needle biopsy and highlighting some of the recent advancements and controversies in the field.

Introduction: Gastric emptying scintigraphy (GES) is a safe, noninvasive method for assessing the ability of the stomach to empty which has been used clinically for many years. It is considered as a “gold standard” to assess gastric emptying of both solids and liquids allowing assessment of early, mid and late emptying, each of which may be altered by pathology. The aim of the study was to analyse standard diagnostic approach and evaluate patients` radiation exposure, who underwent GES in Slovakia. Methods: A retrospective cohort study included 55 patients from 2 departments of nuclear medicine (department A, B). Patients’ radiation exposure was determined by dosimetry program IDAC-Dose2.1. The radiopharmaceutical 99mTc-DTPA, always with the same activity, was applied orally to patients at Department B. The applied activity of the radiopharmaceutical at GES was 185 MBq. The radiopharmaceutical 99mTc MAA, with various activity, was applied orally to patients at Department A. Results: According to ICRP60, the eff ective dose (ED) of every patient undergoing GES was 0.77 mSv and, according to ICRP103, the dose was 0.836 mSv at Department B. Patients at Department A were exposed to ionizing radiation with 5-times lower intensity, compared with patients at Department B. It was caused by radiopharmaceutical activity correction. The ED medians according to ICRP60, and according to ICRP103 were 0.167 mSv (range 0.105–0.208 mSv) and 0.181 mSv (range 0.113–0.226 mSv) at Department A, respectively. Discussion: Adequate correction of applied radiopharmaceutical activity is an essential part of GES guidelines and in accordance with ALARA principles. For the accuracy of GES examination, it is necessary to follow a standard 4-hour protocol and an approach which ensures full-featured utilization of the examination while decreasing patient`s radiation exposure. Conclusion: The results of our study show relatively low ED associated with GES, but also confi rm that the GES methodology significantly affects the patient`s radiation exposure

ABSTRACT Objective: To identify the incidence of injuries, their main characteristics, and the way they were managed throughout 2016 in two major series of a professional soccer championship in São Paulo, Brazil. Methods: This prospective study used an electronic questionnaire previously developed by the Medical Committee of the Paulista Soccer Federation which was sent to the team doctors after each match. Results: Two hundred and fifty-nine injuries occurred during 361 matches, and the incidence of injury per 1000 hours of game play was 21.32. Strikers were the most affected by injury; the most frequent diagnosis was muscle injury and the legs were predominantly affected. Most of the injuries occurred in the last 15 minutes of the first half and only 7.7% required surgical treatment. Conclusions: Muscle injuries were the most frequent, with most occurring in forwards and in the legs. Approximately half of the injuries occurred after contact and the vast majority was treated without surgery. MRI was the most requested exam and most injuries were classified as moderate (8 to 28 lost play days). Level of Evidence III, Study of Non Consecutive Patients; Without Consistently Applied Reference “Gold” Standard.
