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.
