title: Diffuse elevated MIBG activity in the renal parenchyma caused by compromised renal blood flow.
abstract: Increased metaiodobenzylguanidine (MIBG) activity in the kidneys is usually focal and commonly attributed to radioactive urine accumulation in the renal pelvis. Hereby, we present 2 cases of abnormal diffuse MIBG activity in the kidneys caused by compromised renal blood flow. The patterns should be differentiated from physiologic renal MIBG activity, especially when the uptake is relatively symmetric as well as from regional MIBG-avid disease.
