Overall, 6 arterial sub-phases TWIST-VIBE showed higher detection of recurrent HCCs compared with the equivalent-to-conventional single arterial phase exams by providing an optimized wide observation window for tumor vascularity evaluation. This is especially valuable in improving the detection of hypervascular recurrent HCCs with diameters of less than 2cm.
