“…4 MDCT arthrography of the shoulder requires the intraarticular injection of a contrast agent into the joint prior to the acquisition of CT images of the shoulder. 5 Through the resultant increase in contrast resolution and joint distention, intra-articular contrast material improves visualization of the capsule, tendons, labrum, and hyaline cartilage, and it increases the conspicuity of intra-articular abnormalities. Additionally, the distribution of contrast material in and around the joint delivers functional information, such as the presence or absence of decompression of intra-articularly injected contrast-enhanced fluid through a full-thickness rotator cuff defect into the subacromial-subdeltoid bursa.…”

High-resolution multidetector computed tomography (MDCT) arthrography of the shoulder can diagnose internal derangement of the glenohumeral joints including abnormalities of the rotator cuff, glenoid labrum, and articular cartilage. Isotropic data sets and postprocessing techniques enable interactive three-dimensional image analysis that is capable of reducing artifacts for metal implants. In this article, we review the indications for MDCT arthrography of the shoulder, highlight techniques and important features of the MDCT acquisition, and review normal and abnormal MDCT arthrography appearances of the glenohumeral joint.

“…Unstable shoulders (29) Seventeen diagnoses were of shoulder instability (15 anteriorly and 2 posteriorly), supported by clinical manifestations and CT arthrographic findings. In 10 shoulders, the clinical diagnoses and CT arthrographic findings were substantiated at surgery.…”

Computed tomography (CT) arthrography of shoulder instabilities in athletes

et al. 1988

Sixty professional and recreational athletes underwent CT arthrography of the shoulder for evaluation of suspected shoulder joint derangement. These athletes, 46 males and 14 females ranging in age from 15 to 60 years (mean, 32 years), all had persistent pain that interfered with their sports activity and was resistant to conservative treatment. Seventeen patients had shoulder instability based on clinical manifestations and CT arthrographic findings. An additional five patients, also based on clinical manifestations and CT arthrographic findings, were considered to have an unobtrusive degree of anterior joint laxity. Patients with anterior instability (20 cases) all had an anteroinferior tear or detachment of the glenoid labrum, as well as some violation of the insertion of the joint capsule onto the scapula. Those with posterior instability (two cases) had a combination of labral and capsular tears. Two other major patterns of labral tears, both unaffiliated with shoulder instability, were identified. These included total or partial detachment of superior segments of the labrum, and anterior labral tears at the midglenoid level. Moreover, various degrees of labral attenuation (or, less often, enlargement), osteophyte formation, and alterations in articular cartilage were observed. Surgical correlation was obtained in 25 patients, with 95% accuracy of CT arthrographic findings. CT arthrography is a minimally invasive and highly accurate technique for investigation of glenohumeral derangement. Specifically, the extent of pathologic changes associated with instability can be determined and differentiated from other intraarticular causes of incapacity, such as labral tears caused by throwing, or degenerative changes.

“…In functional instability, the joint is clinically stable, but the patient suffers chronic pain, clicking, or locking as well as a sensation of instability. These patients have in the past been evaluated by arthrography, arthrotomography, or CT arthrography [25,34]. Until recently CT double-contrast arthrography has been the technique of choice and has been able to demonstrate the commonly occurring abnormalities in these patients.…”

Magnetic resonance imaging of the shoulder: rationale and current applications

et al. 1990

Because it can demonstrate a wide range of tissue contrast with excellent resolution, magnetic resonance (MR) imaging has revolutionized imaging in many areas of the musculoskeletal system and has generated excitement among those interested in the painful shoulder. Shoulder impingement syndrome and glenohumeral instability constitute the two major categories of shoulder derangements. Correct diagnosis requires the use of appropriate pulse sequences and imaging planes, proper patient positioning, and a satisfactory surface coil. In addition the imager must have a thorough understanding of shoulder anatomy and pathology. We present a summary of the current status of MR imaging of the shoulder including technical, anatomic, and pathologic considerations and a review of the pertinent literature.
