Multisection cerebral blood flow MR imaging with continuous arterial spin labeling.
A method was evaluated to control for off-resonance saturation in noninvasive magnetic resonance imaging with continuous arterial spin labeling of cerebral blood flow. In phantoms and humans, application of amplitude-modulated radio-frequency irradiation during the control image corrected for saturation across the whole brain and made possible cerebral blood flow imaging in multiple sections at arbitrary angles to the labeling plane.
