6/2012: Novel PET/CT device offers insight into inflammatory arthritis (Auntminnie)

11/2011: Rheumatology Rewards Innovative Imaging

Brief description

Our research group has built a high resolution PET/CT scanner for imaging human extremities. We are employing the device to study the pathogenesis of inflammatory arthritis such as Rheumatoid and Psoriatic Arthritis through clinical trials in humans. We are also testing the scanner for its ability to monitor response to biologic treatment earlier than the conventional clinical work-up. In the adjoining figure, we show a picture of the system and high resolution PET/CT imaging of the finger and wrist in inflammatory arthritis patients. The radiotracer used for PET was 18F-FDG and correlative analyses of PET against MRI are provided. The finger image and the hand image are both award-winning images in the fields of rheumatology and nuclear medicine.
