Significant differences between magnetic resonance imaging reports and intraoperative findings at the time of hip arthroscopy were documented in our practice. We sought to examine the accuracy of radiological reporting of hip pathology based on the training level of the reporting radiologist. A retrospective review of hip arthroscopies carried out between(More)
OBJECTIVE The objectives of our study were, first, to use MRI to determine the prevalence of osteitis pubis and of adductor dysfunction at the symphysis pubis in soccer players presenting with pubalgia and, second, to determine whether the two entities are mechanically related and whether one of the entities precedes or predisposes the development of the(More)
Corticosteroids and local anesthetics are some of the most commonly administered medications in radiology departments. These medications have marked variability in their formulations, which may increase their adverse event profile for specific procedures. In particular, certain corticosteroid preparations are associated with adverse central nervous system(More)
Although most muscle injuries in the athlete are diagnosed clinically, MR imaging is an excellent noninvasive diagnostic adjunct to clinical examination, which allows the site and severity of muscle injury to be assessed accurately, influencing therapy and overall outcome. There has been a rapid expansion in the clinical use of MR imaging during the past(More)
OBJECTIVE MRI is routinely performed to evaluate acute complex knee injuries. This article will review the fundamental biomechanical forces underlying the most important and common injuries and correlate MRI findings with specific traumatic mechanisms. CONCLUSION MRI findings can reveal the traumatic mechanisms in many acute knee injuries. By applying a(More)
The objective of this study was to assess the utility of MRI in diagnosing injury to the first interosseous cuneometatarsal (Lisfranc) ligament and to additionally determine the associated patterns of traumatic soft tissue and osseous injury. Fifteen patients (16 feet) who were referred for MRI evaluation of the Lisfranc ligament, and had operative(More)
BACKGROUND AND PURPOSE Transforaminal CS injections have been associated with severe adverse CNS events, including brain and spinal cord infarction. Our purpose was to describe the static and dynamic microscopic appearances of CS preparations, with an emphasis on their potential to cause adverse central nervous system events by embolic mechanisms during(More)
Molecular imaging has the potential to transform the field of diagnostic imaging through enabling far more detailed investigation and characterisation of disease processes than is currently possible. Magnetic resonance imaging (MRI) is capable of three-dimensional non-invasive imaging of opaque tissues at near cellular resolution. Among the imaging(More)
PURPOSE To evaluate the accuracy of the conventional transrectal ultrasonographic (US) prostate volume formula and determine whether a more accurate volume formula, calculated on the basis of prostate shape as observed at planimetry, can be described for the majority of prostate glands. MATERIALS AND METHODS This retrospective study was institutional(More)
AIM To define the 100 citation classic papers of interventional radiology. METHODS Using the database of Journal Citation Reports the 40 highest impact factor radiology journals were chosen. From these journals the 100 most cited interventional radiology papers were chosen and analysed. RESULTS The top paper received 2497 citations and the 100(th) paper(More)
