Perfusion
originating from the summed supply of all brain feeding arteries is commonly
assessed. In this study, a slice selective inversion was compared to a
multidimensional RF pulse to label only the artery of interest. By tagging
the bypass of a patient, perfusion signal only exists in the according
hemisphere of the brain. The perfusion measured by these SASL methods is
consistent with a standard angiography. Therefore, these presented MR
techniques may in part replace the assessment of revascularization success by
conventional angiography.
