OBJECTIVE: Because positron emission tomography/computed tomography (PET/CT) using @entity419 ( @entity419 ) can be used to visualize @entity85 , it may help elucidate the pathophysiology of @entity2585 ( @entity2585 ). The purpose of this study was to characterize the uptake pattern on @entity419 PET/CT in @entity1 with idiopathic @entity2585 and to determine if there is a correlation between its metabolic parameters and clinical findings. METHODS: @entity419 PET/CT was conducted to 35 @entity1 with unilateral idiopathic @entity2585 . Clinical data including @entity158 , functional scores, and passive range of motion (ROM) were collected. Maximum standardized uptake values (SUVmax) were measured at the four regions of interest (ROIs): rotator interval (RI), anterior joint capsule (AJC), axillary recess (AR), and posterior joint capsule (PJC) from the attenuation-corrected axial images. RESULTS: Mean SUVmax values for four ROIs of the affected shoulder were significantly higher than those of the unaffected shoulder. Mean SUVmax values of RI and AR were significantly higher than those of AJC and PJC and mean SUVmax of AJC was significantly higher than that of PJC in the affected side. Three recognizable patterns of increased uptake were noted: (1) AR dominant type (15 @entity1 ); (2) RI dominant type (9 @entity1 ); (3) both RI and AR dominant type (11 @entity1 ). The SUVmax of AR showed negative correlation with abduction and forward flexion. The SUVmax of RI showed negative correlation with external rotation and internal rotation. The SUVmax of AJC showed negative correlation with all ROMs. However, there was no significant correlation between the SUVmax of PJC and any ROM. CONCLUSION: Our study demonstrates that the anterior-inferior capsular portion, including RI and AR, is the main pathologic site of idiopathic @entity2585 and reveals significant correlations between ROM and metabolic parameters on @entity419 PET/CT. These results imply that AR and @entity717 are related to elevational limitations and rotational limitations, respectively.
