From: Evaluation of liver function using Gd-EOB-DTPA-enhanced MRI with T1 mapping
Images of the same patient Pre- and postcontrast T1 maps. The liver function assessment results placed the patient in the LCA group and the ALBI1 group. The left figure shows a plain scan, and the right image shows the scan acquired 20 min after Gd-EOB-DTPA injection. Five ROIs of equal size were drawn at the level of the porta hepatis to ensure that the ROI was at the same level and in the same position before and after enhancement as much as possible. The mean value was calculated as the T1 value of the whole liver
