OBJECTIVE To evaluate the diagnostic performance of magnetic resonance (MR) arthrography of the shoulder in the diagnosis of anteroinferior labrum lesions, using arthroscopy as the reference standard and to classify these lesions. METHODS Institutional review board approval was obtained. The study population included 59 consecutive patients with history and clinical diagnosis of acute or chro...

Since January 1993 we have carried out MR arthrography on 23 patients with clinical symptoms and signs of abnormality of the acetabular labrum. Most of the patients were young adults. Such symptoms are known precursors of osteoarthritis, and therefore early and accurate evaluation is required. We assessed the value of MR arthrography of the hip as a minimally-invasive diagnostic technique, in a...

Objective: To determine the reliability and accuracy of magnetic resonance arthrography of the shoulder for the diagnosis of anteroinferior labroligamentous lesions in patients with gleno-humeral joint instability. Methodology: This retrospective study was performed at King Hussein Medical Center in Jordan. Twenty eight patients who underwent shoulder MR arthrogram and arthroscopy during a 22-m...

OBJECTIVE The purpose of this study was to compare the diagnostic accuracy of MRI, MR arthrography, and ultrasound for the diagnosis of rotator cuff tears through a meta-analysis of the studies in the literature. MATERIALS AND METHODS Articles reporting the sensitivities and specificities of MRI, MR arthrography, or ultrasound for the diagnosis of rotator cuff tears were identified. Surgical ...

PURPOSE To compare magnetic resonance (MR) arthrography and arthroscopy as a means of assessing the severity of labral tear in anterior glenohumeral instability. METHODS 52 patients presenting with traumatic recurrent anterior shoulder instability were evaluated using MR arthrography; 30 shoulders with a labroligamentous lesion were treated with arthroscopic Bankart repair. Their MR arthrogra...

Magnetic resonance (MR) arthrography of the wrist and elbow is useful for detecting a variety of intra-articular pathologies. MR dictations should address whether intrinsic ligament tears of the wrist are partial-thickness or full-thickness, and involve the dorsal, membranous, and/or volar components of the ligaments. With regard to elbow soft tissue pathology, partial-thickness tears of the an...

OBJECTIVE To investigate the use of low-field magnetic resonance imaging (MRI) and MR arthrography in normal canine stifles and to compare MRI images to gross dissection. STUDY DESIGN Descriptive study. SAMPLE POPULATION Adult canine pelvic limbs (n=17). METHODS Stifle joints from 12 dogs were examined by orthopedic and radiographic examination, synovial fluid analysis, and MRI performed ...

OBJECTIVE Hip arthrography is an accurate diagnostic method for evaluation of the peripheral compartment, but its depiction of cartilage lesions is moderate. The purpose of this study was to add leg traction to MR arthrography of the hip to test its effect on visualization of cartilage surfaces. CONCLUSION Hip MR arthrography with leg traction is a technically feasible and safe procedure that...

Introduction Hip arthrography is considered of importance in tailoring treatment in children with LCPD [l-3]. Hip arthrography in children with LCPD is employed for dynamic imaging to determine congruency and containment of the femoral head by the acetabulum as well as to rule out “hinge abduction” [3]. Information obtained by hip arthrography may help in selecting candidates for operative trea...

The purpose of this review was to demonstrate magnetic resonance (MR) arthrography findings of anatomy, variants, and pathologic conditions of the superior glenohumeral ligament (SGHL). This review also demonstrates the applicability of a new MR arthrography sequence in the anterosuperior portion of the glenohumeral joint. The SGHL is a very important anatomical structure in the rotator interva...
