Fluoroscopically-Guided Posterior Approach for Shoulder Magnetic Resonance Arthrography: Comparison with Conventional Anterior Approach

MR arthrography of the shoulder: fluoroscopically guided technique using a posterior approach.

433 R arthrography is the preferred imaging technique for the investigation of patients with shoulder instability [1, 2]. MR arthrography reliably shows subtle lesions of the labroligamentous complex, providing information essential to the surgeon concerning the surgery or arthroscopic repair. Most patients presenting with shoulder instability have anterior instability; in these cases, evaluati...

Magnetic resonance arthrography of the glenohumeral joint: ultrasonography-guided technique using a posterior approach.

OBJECTIVE The purpose of this study was to assess the efficacy and feasibility of ultrasound (US)-guided magnetic resonance (MR) arthrography of the glenohumeral joint via a posterior approach. MATERIALS AND METHODS Thirty-four patients (18 males and 16 females) who were suspected to have glenohumeral joint pathology were examined using MR arthrography. The patients ranged in age from 21 to 8...

Direct magnetic resonance arthrography, indirect magnetic resonance arthrography, and computed tomography arthrography for rotator cuff lesions and superior labral anterior and posterior tears: State of the art

Magnetic resonance arthrography in recurrent anterior shoulder instability as compared to arthroscopy: a prospective comparative study.

AIM To evaluate the accuracy of magnetic resonance (MR) arthrographic imaging in the diagnosis of glenoid labral and ligament tears in recurrent shoulder instability. SETTINGS AND DESIGN Prospective, comparative study at a tertiary care centre. MATERIAL AND METHODS Patients with three or more episodes of anterior shoulder dislocation were enrolled in the study. They were subjected to magnet...

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...
