Summary: | The purpose of our study was to demonstrate metabolic patterns on ^sup 18^F-fluorodeoxyglucose positron emission tomography/computed tomography (^sup 18^F-FDG PET/CT) in patients with adhesive capsulitis (AC). We retrospectively reviewed ^sup 18^F-FDG PET/CT performed on 22 shoulders of 21 patients diagnosed with AC: 2 shoulders with stage I, 14 with stage II, and 6 with stage III. A clinical diagnosis of AC was retrospectively made based on clinical examination, clinical course, and imaging. The pattern of radiotracer uptake was analyzed. Standardized uptake values in rotator interval (RI), anterior joint capsule (AJC), axillary recess (AR), and greater tuberosity were measured and compared to those of the contralateral side and the control group consisting of 40 shoulders in 20 subjects without shoulder pain. Four patterns of uptake were noted: (1) glenoid type I (n = 16), with uptake in RI, AJC, and AR; (2) glenoid type II (n = 2),with uptake in AJC and AR; (3) glenoid type III (n = 2), with uptake in RI and AJC; (4) focal type (n = 2), with uptake in RI or AR. Affected side SUV^sub max^ for RI, AJC, and AR was significantly higher compared with the unaffected side and the control group. Two shoulders with stage I AC had patterns similar to the ones with stage II or III. Specific patterns of ^sup 18^F-FDG uptake with dominant uptake in RI, AJC, or AR may be related to AC.[PUBLICATION ABSTRACT] |
