New Imaging Strategies Using a Motion-Resistant Liver Sequence in Uncooperative Patients

MR images obtained in a 68-year-old woman for workup of metastasis. Contrast-enhanced dynamic 3D radial GRE using KWIC during hepatic arterial dominant phase imaging comprised four subframe images. The full-frame 3D radial GRE (a) image shows homogenous enhancement in the portal vein, but not in the hepatic vein. The first subframe image (b) obtained at 5-second temporal resolution demonstrates minimal portal venous enhancement with laminar flow (arrow). On the next serial three subframe images ((c)–(e)), the portal vein and hepatic parenchyma have gradually increasing enhancement.
