Magnetic Resonance Imaging of the Elbow: Update on Current Techniques and Indications

Correlation of Preoperative MRI and MRA With Arthroscopically Proven Articular Cartilage Lesions of the Elbow

“…18 The more recent use of gradient-echo sequences, in combination with short tau inversion recovery sequence (for fat suppression) may be better in evaluating articular cartilage and to better delineate loose bodies in the elbow joint; it may also be that 3T MRI will improve the accuracy of the diagnosis of articular cartilage defect compared with the 1.5 T MRI technology used in this study, although this has yet to be demonstrated. 7,[19][20][21] In our series of 31 patients, in comparison with MRI, the use of MRA did not increase the diagnostic accuracy of detecting chondral lesions of any of the 4 anatomical lesions. This is in contrast to the known effects of MRA in enhancing visualization of capsular abnormalities, undersurface collateral ligament tears, OCD, and intraarticular loose bodies.…”

“…This is in contrast to the known effects of MRA in enhancing visualization of capsular abnormalities, undersurface collateral ligament tears, OCD, and intraarticular loose bodies. 3,6,14,19,[21][22][23] However, the difficulty in interpreting magnetic resonance arthrograms of the elbow has been noted by Cotton et al, 24 who described potential diagnostic pitfalls such as fat pads projecting into the joint, synovial folds, and cartilaginous pseudodefects. Pseudodefects can occur on the capitellum because of the abrupt transition between the posterior capitellum and the lateral epicondyle and on the trochlea groove at the junction of the olecranon and the coronoid process.…”

The detection of the capsular tear at the undersurface of the extensor carpi radialis brevis tendon in chronic tennis elbow: the value of magnetic resonance imaging and computed tomography arthrography

“…MRI is used to diagnose the cause that contributes to the clinical entity of tennis elbow when conservative treatment fails. 3 A metaanalysis 14 indicated that the increased T2-weighted signal intensity of the common extensor tendon is the most common findings and is present in 90% of patients with lateral epicondylitis. No study has been published that focuses on the correlation between the increased signal foci and arthroscopic findings of tennis elbow.…”

“…3,8 Further studies are required to validate the effectiveness of MRI arthrography compared with those that we studied.…”

Arthrose du coude

“…Les corps étrangers responsables de blocage sont souvent détec-tés aussi bien sur la radiographie standard que par IRM ou par scanner avec des spécificités comparables, mais une moins bonne sensibilité pour l'IRM [10,11].…”
