Liver black blood imaging helps to detect and characterize focal liver lesions and thus is highly desirable clinically. The commonly used low b-value DWI sequence is limited due to inherent limitations of EPI, such as low spatial resolution and motion artifacts including blurring and ghosting. We proposed a 3D whole liver black blood imaging solution within 3 min. By combining with existing black blood preparation, a respiratory triggered VISTA sequence and a free breathing imaging technique utilizing GROWL reconstruction were proposed. Six healthy volunteers with stable and irregular respiration were scanned to further validate the feasibility of our proposed solution.
