Indirect MR arthrography is useful for evaluation of joints such as the elbow, wrist, ankle and shoulder where there is a large synovial surface area relative to joint volume. It allows simultaneous assessment of both intra-articular and extra-articular soft tissues with the added advantage of minimal invasiveness. The established and potential uses of this imaging technique are reviewed below and the pathology that is demonstrated by this technique is discussed.
OBJECTIVE: To examine the accuracy of Grashey views obtained during shoulder arthrography in the diagnosis of clinically relevant superior labrum anterior-posterior (SLAP) lesions. DESIGN AND PATIENTS: Grashey views obtained during diagnostic arthrography (conventional and MR) were used to examine the superior labrum. Twenty-eight of 118 shoulder arthrograms obtained during a 27-month period fulfilled study criteria and were correlated for accuracy using arthroscopically confirmed grade 2-4 SLAP lesions as the standard of reference. Arthrograms were graded using the consensus method. Prevalence, sensitivity, specificity, and accuracy were 21%, 50%, 86%, and 79%. The appearance of the superior labrum on the Grashey view was compared subjectively with MR arthrography. Sources of errors were analyzed. CONCLUSION: Grashey views obtained during shoulder arthrography can diagnose clinically relevant SLAP lesions with moderately high specificity, moderate accuracy, and limited sensitivity. Findings on the Grashey view closely resemble those seen on coronal oblique MR arthrography. Grashey views should be considered in patients undergoing shoulder arthrography.
Bilateral facet dislocation of the lumbosacral joint is an uncommon injury. We report on the imaging findings in a patient who had an acute disc herniation associated with a bilateral traumatic lumbosacral dislocation.
