The Differences of Cerebral Hyperperfusion in Patients With Moyamoya Disease and Atherosclerotic Occlusive Cerebrovascular Disease Evaluated by 99mTc-ECD SPECT One Day After Revascularization Surgery

CHP in the frontal lobe occurred more often and with greater severity in patients with AMMD. Preoperative CBF reduction was more closely associated with CHP than CVR in patients with MMD. Nonactivated 99m Tc-ethyl cysteinate dimer SPECT was suitable for preoperative/postoperative CBF evaluations.
