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

Figure 7

MR images in a 65-year-old man with liver cirrhosis. The conventional breath-hold T1-weighted 3D GRE sequence (acquisition time: 23 seconds) and the CAIPIRINHA 3D GRE sequence (acquisition time: 12 seconds) were obtained during the early hepatic venous phase. T1-weighted 3D GRE (a) shows blurred resolution of the intrahepatic vessel and the hepatic margin caused by motion artifacts. Much greater sharpness of the hepatic edge and a clearer depiction of the intrahepatic vessel are shown on the T1-weighted 3D CAIPIRINHA GRE sequence.
