Abstract
A method of magnetic resonance imaging (100, 200) includes acquiring (300) tagged magnetic resonance data (144) by controlling the magnetic resonance imaging system with tagging pulse sequence commands (140). The tagging pulse sequence commands include a tagging inversion pulse portion (404) for spin labeling a tagging location (122, 122′) within a subject (118). The tagging pulse sequence commands comprise a phase-contrast readout portion (406) which phase-contrast encodes in at least one direction. The control pulse sequence commands include a control inversion pulse portion (500) and the phase-contrast readout portion. A tagged magnitude image (148) is reconstructed (304) using the tagged magnetic resonance data. A control magnitude image (150) is reconstructed (306) using the control magnetic resonance data. An arterial image (152) is reconstructed (308) by subtracting the control magnitude image and the tagged magnitude image. At least one phase image (156, 158, 160) is reconstructed (312) using either the tagged magnetic resonance data and/or the control magnetic resonance data.
