Magnetic resonance perfusion imaging of arterial spin labeling is a technique to quantificationally measure the cerebral blood flow using the labeling arterial blood as a endogenous tracer.
Perfusion MR images were obtained with spin-echo echo planar imaging (SE-EPI) techniques.

But unlike the spin of a top, proton spin governs the magnetic interactions between protons and other particles, a property that permits magnetic-resonance imaging (MRI).
