Arterial Spin Labeling (ASL) was compared with H215O Positron Emission Tomography (PET), the current gold standard for non-invasive quantification of CBF, in patients with type 1 diabetes and healthy subjects. The ASL variant used was pseudo-continuous, with background suppression, and a 3D FSE spiral readout. Both methods were compared in terms of absolute quantification and regional differences.
