Role of 99mTc MDP bone and 67Gallium imaging in evaluation of diabetic osteopathy

Our study shows three-phase bone scan has 100% sensitivity and 91.2% specificity for detecting diabetic Osteomyelitis in presence of normal X-rays. Bone scan is a simple and useful screening modality to detect OM and unsuspected cases of Charcot's foot in diabetics. Navicular and cuneiform bones are earliest to be involved in Charcot's foot. 67Gallium imaging has little incremental value in evaluation of diabetic osteopathy.
