Does Immobilization Post Injection Reduce Contrast Extravasation in MR Arthrography of the Shoulder?

Posterior shoulder injection under MDCT guidance before MR arthrography

MR and CT arthrography of the shoulder.

The combined use of shoulder arthrography with MR and CT imaging offers distinct advantages over conventional nonarthrographic imaging techniques. The improved contrast and joint distension afforded by direct arthrography optimize evaluation of various intra-articular structures and help to define subtle abnormalities and distinguish normal variants from true shoulder pathology. In this article...

MR arthrography of the shoulder using an anterior approach: optimal injection site.

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...

MR arthrography of the shoulder: a pictorial educational review

Pain & resistance in patients with adhesive capsulitis during contrast material injection phase of MR arthrography.

BACKGROUND & OBJECTIVE Adhesive capsulitis of the shoulder is a condition of unknown aetiology that results in the development of restricted active and passive glenohumeral motion. It has been reported that magnetic resonance (MR) imaging is useful in diagnosing adhesive capsulitis. We carried out this study to assess how pain and/or resistance during contrast material injection affects the dia...
