Arterial spin-labeling in routine clinical practice: a preliminary experience of 200 cases and correlation with MRI and clinical findings.

ABSTRACT

We described our experience with a heterogeneous collection of 200 arterial spin-labeling (ASL) perfusion cases. ASL imaging was performed on a 1.5-T magnetic resonance imaging unit with a receive head coil using a second version of quantitative perfusion imaging. Sixty-four (32%) patients exhibited normal perfusion, 107 (53.5%) patients exhibited hypoperfusion, and 29 (14.5%) exhibited hyperperfusion. This ASL study illustrates the usefulness of ASL perfusion studies in a number of pathological conditions and that perfusion imaging can be implemented successfully in a routine clinical neuroimaging protocol.
