Dynamic contrast-enhanced T1w-3D-fs-GRE with multi-arterial volumetric interpolated breath-hold examination (multi-arterial VIBE) allows for the acquistion of five arterial subphases during a single breath-hold. The diagnostic performance of this technique was studied in twenty-five patients with known focal liver lesions. Two independent readers evaluated the diagnostic value of the five dynamic arterial subphases compared to the standard hepatic arterial, portal venous, delayed and hepatobiliary phases and the single shot turbo-spin echo sequence. Multi-arterial VIBE demonstrated greater diagnostic accuary at the detection of hypervascularized focal liver lesions as compared to the hepatic arterial standard phase.
