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.
