ABSTRACT

We aimed to compare the efficacies of SPECT/CT and planar imaging of joints after radiosynovectomy.

Six patients with hemophylic arthropathy (HA) (5 hemophilia A, 1 hemophilia B) with a mean age 10.5 (range between 8-15) underwent radiosynovectomy in our clinic between January 2004-December 2012. Postradiosynovectomy planar and SPECT-CT imaging of 5 knee joints, 1 elbow joint and two ankle joints were obtained.

Distribution pattern of activity showed no difference between SPECT/CT and planar imaging methods. In one patient there was loculation of activity in suprapatellar recess detected with SPECT/CT which was not deliniated in planar image.

Addition of SPECT/CT to the postradiosynovectomy imaging protocol might help in identification of those who are at risk for potentially serious local complications.
