Abstract:
1. A method of magnetic resonance (MR) imaging, the method comprising: acquiring a succession of MR image pairs responsive to a succession of arterial spin labeling (ASL) pulse sequences, wherein each MR image pair is acquired responsive to a corresponding one of the successive ASL pulse sequences followed by a corresponding delay period; processing the acquired series of MR image pairs to measure arterial blood flow and transit delay of a target tissue; wherein acquiring the succession of MR image pairs includes: wherein processing the acquired succession of MR image pairs to measure arterial blood flow includes subtracting the control MR image from the labeled MR image for each MR image pair; wherein processing the acquired series of MR image pairs to measure the transit delay includes processing the acquired series of MR images to identify a time period for the magnetically labeled arterial blood to transit from the labeling region to the imaging region and appear on the labeled MR images; and wherein a repetition time (TR) representing an amount of time between each successive ASL pulse sequence is varied.
