摘要：The present invention provides the object (118) of operation magneticresonance imaging system (100,200) imaging. This method includes the magnetic
resonance imaging system for obtaining the MR data (144) of (300) label, passes throughcontrol pulse train and tab command (140). Marker sequence command includes labelinversion pulses part (404) for the object in spin labeling mark position (122,122 '). Markersequence command includes difference reading section (406). Phase contrast readingsection includes phase contrast coding at least one direction. This method furtherincludes obtaining (302) control MR data to pass through control magnetic resonanceimaging system, with the order of control pulse train, wherein the order includes thesegment pulse (500) of control reversion control pulse train, wherein control pulse trainorder includes phase contrast reading section. This method further includes
reconstructing the magnitude image (148) that (304) mark to use the MR data marked.This method further includes that reconstruct (306) control magnitude image (150) usescontrol MR data. This method further include: the magnitude image in span of controllimit of control image and label is subtracted in building (308) arterial images (152). Thismethod further includes reconstructing (312) at least one phase image (156,158,160) or
MR data and/or control MR data with label. At least one phase diagram is rebuild, usingphase code at least one direction.
