Accuracy of palpation-directed intra-articular glenohumeral injection confirmed by magnetic resonance arthrography.

Purpose: The aim of this study was to determine the accuracy of anatomic palpation-directed injections in the office setting.

Methods: Two hundred twenty-six shoulders in 208 patients were studied using a 0.2-Tesla extremity scanner after the injection of gadolinium-diethylene triamine pentaacetic acid-saline.

Analysis of Low-Field MRI Scanners for Evaluation of Shoulder Pathology Based on Arthroscopy.

Background: Many studies have compared the diagnostic capabilities of low-field magnetic resonance imaging (MRI) scanners to high-field MRI scanners; however, few have evaluated the low-field MRI diagnoses compared with intraoperative findings.

Purpose: To determine the accuracy and sensitivity of low-field MRI scanners in diagnosing lesions of the rotator cuff and glenoid labrum.

Study Design: Cohort study (diagnosis); Level of evidence, 3.
