Abstract
A magnetic resonance imaging (MRI) system, method and/or computer readable medium is configured to effect MR imaging based upon arterial spin labeling (ASL) using a tagging image and a control image. The tagging image is based upon applying a tagging pulse train including a plurality of saturation pulses to a tagging area followed by applying a first imaging pulse train to an imaging area; and the control image is based upon applying a control pulse train to a control area followed by applying a second imaging pulse train to the imaging area. The tagging area, the control area, and the imaging area are located at respectively different positions in relation to the object being imaged.
