OBJECTIVE: Adhesive capsulitis (frozen shoulder) is a common condition characterized by pain and progressive restriction of shoulder mobility, often requiring imaging for differential diagnosis. While bone scintigraphy is occasionally performed, the diagnostic potential of bloodpool SPECT/CT has never been evaluated.
METHODS: We retrospectively analyzed 18 affected shoulders in 17 patients who underwent standardized bone scintigraphy with both bloodpool and late-phase SPECT/CT. Uptake was visually assessed in four predefined capsular regions.
RESULTS: Bloodpool SPECT/CT revealed increased uptake in the rotator cuff interval in 100% of pathological shoulders, followed by the axillary recess (72%), anterior joint capsule (67%), and posterior joint capsule (44%). Late-phase diffuse uptake was present in 78% of cases. In three pathological shoulders, uptake in the rotator cuff interval was the only abnormality at the bloodpool phase.
CONCLUSION: This study suggests that increased uptake in the rotator cuff interval on bloodpool SPECT/CT may be associated with adhesive capsulitis and could represent a sensitive imaging pattern. Further prospective studies are required to determine the diagnostic value of blood-pool SPECT/CT in patients with shoulder pain.
