Background: MR arthrography in the abduction and external rotation (ABER) position has been demonstrated to enhance diagnostic ratio of anterior labro-ligamentous complex tears. Meanwhile, discriminatory rates this various types antero-inferior lesions have not completely discovered. Aim: This study aimed perform comparison between ABER conventional considering rate precision anteroinferior les...

This article reviews many of the most commonly used modalities for imaging the hand and wrist. Particular attention is paid to proper radiographic positioning, with emphasis on the four-view wrist series. Standard wrist measurements are detailed, and wrist arthrography is also discussed. Techniques for cross-sectional imaging, computed tomography, and MR imaging are reviewed, and several exampl...

Magnetic resonance (MR) imaging can be a very useful tool in the evaluation of instability in the athlete's shoulder. Technical options of MR imaging, such as arthrography, higher power magnets, and shoulder positioning, have enhanced MR evaluation of the shoulder. This update discusses the application of new MR techniques to a variety of shoulder instability patterns, including anterior instab...

OBJECTIVE The purpose of our study was to optimize anterior MR arthrography of the shoulder by comparing three injection sites. MATERIALS AND METHODS Seventy-eight patients were divided into three groups of 26 each, according to the injection site selected: the upper third of the medial part of the humeral head, the lower third of the medial part of the humeral head, or the area between the m...

PURPOSE To assess the relationship between mandibular asymmetry and disorders of the temporomandibular joint. METHODS We used advanced imaging of the temporomandibular joint to distinguish different causes of mandibular asymmetry. MR imaging and arthrography were applied to the temporomandibular joints of 11 patients presenting with mandibular asymmetry. RESULTS Condyle hyperplasia was iden...
