The purpose of this study was to evaluate the correlation between indirect MR arthrographic findings and clinical findings, and wheter MR findings can reflect the prognosis in primary adhesive capsulitis.

We evaluated 69 patients with primary adhesive capsulitis of the shoulder, the mean age was 54.5 years (standard deviation 8.3). Capsular thickness of the axillary pouch, capsular enhancement of the axillary pouch and soft tissue thickening of rotator interval on indirect MR arthrographic images were investigated. Severities of clinical symptom were evaluated by three scoring systems (Simple Shoulder Test, Contant Score, and ASES). Comparing with clinical symptoms after 6 months, we analyzed whether MRI finding correlated with prognosis of adhesive capsulitis.

Capsular thickness and capsular enhancement of the axillary pouch, soft tissue thickening of the rotator interval was significantly higher than normal control group (p < 0.001). Capsular thickness of the axillary pouch was not correlated with clinical symptom by three scoring systems (p = 0.510, 138, 104). In contrast, capsular enhancement of the axillary pouch showed a good correlation with severity of clinical symptom ( p = 0.006, 077, 035). Although soft tissue thickening of the rotator interval was not correlated with severity of clinical symptom ( p = 0.706, 0.612, 0.384), more thickening showed more limitation of motion. Any three findings did not correlate with clinical symptom at 6 months follow-up.

On MR arthrography, capsular enhancement of the axillary pouch showed a good correlation with severity of the clinical symptoms although soft tissue thickening of the rotator interval wasn't.

Indirect MRI arthrography could be an ancillary method for evaluating clinical severity of primary adhesive capsulitis.
