Bone blood flow (BBF) and turnover may be altered in many disease states such as osteoarthritis (OA), bone marrow lesions, and trauma or fracture. Dr. Dyke’s group pioneered the use of pharmacokinetic magnetic resonance imaging (MRI) and positron emission tomography (PET) modeling of various agents to measure BBF and turnover in disease progression of OA, and following injury. These techniques are being used to assess bone healing following total ankle replacement at increasing times post-surgery.
