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.
