Low refocusing flip angle FSE sequence can easily lend to low TE, thereby strong T1 weightings, high SNR and imaging speed that has been used along with fat-water separation with IDEAL reconstruction to satisfactorily null cervical arterial lumens with high conspicuity of arterial walls without using diffusion or gated double IR preparation. This approach may be used for effective black blood imaging to evaluate dissection or carotid plaques with general purpose spine array coils at any field strength within clinically feasible scan times in acute or outpatient settings.
