Figure 6. Human myocardial angiotensin II receptor PET/CT imaging.
Mid-cardiac PET/CT fusion images in a healthy volunteer obtained 1 hour after injection with the angiogensin II type I receptor ligand 11C-KR31173. (Left) At baseline, 11C-KR31173 signal localizes to the ventricular myocardium. (Right) 3 hours after administration of a single 40 mg PO dose of the angiotensin receptor blocker olmesartan, myocardial 11C-KR31173 PET uptake is significantly reduced.
