Xe-CT CBF maps in a patient with Moyamoya disease. Xe-CT CBF maps in a patient with Moyamoya disease. A, Baseline. B, After ACZ administration. Baseline scan (A) shows reduced CBF in the bilateral ACA and anterior watershed areas (areas 1, 2, 19, and 20, asterisk). After ACZ, there is a robust increase in the CBF, indicating a normal cerebral reserve in these territories. There is reduced baseline flow with decreased augmentation of CBF after ACZ, indicating poor cerebral reserve in the left posterior MCA and the left posterior watershed territories (areas 13–15, arrows).
