Triple Arterial Phase CT of the Liver with Radiation Dose Equivalent to That of Single Arterial Phase CT: Initial Experience

The triple arterial phase maximum intensity projection (MIP) protocol is feasible at the same radiation dose as that used with a standard single arterial phase protocol by using a new postprocessing technique. Triple arterial phase MIP provides equivalent to superior image quality and an equal hepatocellular carcinoma detection rate despite using less than half the contrast material dose used at standard single arterial phase CT.
