We enrolled nine and seven rats to
undergo 30% and 70% partial hepatectomy (PH), respectively. All the rats underwent
MRI examinations to obtain T1 and T2 mapping at baseline before surgery, and at
2h, day 1, day 2, day 3, day 5, day 7, day 14, and day 21 after surgery. We drew
the trend charts of the T1 and T2 values and compared the T1 and T2 values in two
groups across different time points. The trend charts of the T1 and T2 values were
similar with some differences, indicating that liver regeneration in the 70% PH
group was more active than that in the 30% PH group. The results suggested that
T1 and T2 mapping are practical techniques to assess liver regeneration after PH.
