A new method has been developed for time-efficient black-blood imaging. The method combines two strategies for a reduction of scan time: multislice acquisition and outer volume suppression to reduce the number of phase encodings. These goals are achieved by using a new MSFQIR (multislice Small-FOV Quadruple Inversion-Recovery) black-blood preparative sequence, which consists of two double-inversion pulse pairs applied in orthogonal planes with appropriate combination of inversion delays. The MSFQIR method demonstrated an improvement in time efficiency and a reduction of motion and flow artifacts in black-blood imaging of the aorta.
