Excerpt
I was interested to read the article titled “Prediction of liver regeneration in recipients after living-donor liver transplantation in using preoperative CT texture analysis and clinical features” by Park et al. [
1]. The purpose of this study was to predict the rate of liver regeneration in recipients after living-donor liver transplantation using preoperative CT texture and shape analysis of the future graft. They included 102 donor–recipient pairs who underwent living-donor liver transplantation using right lobe grafts. They semi-automatically segmented the future graft from preoperative CT. The volume of the future graft (LV
pre) was measured, and texture and shape analyses were performed. The graft liver was segmented from postoperative follow-up CT and the volume of the graft (LV
post) was measured. The regeneration index was defined by the following equation: [(LV
post LV
pre)/LV
pre] × 100(%). They mentioned that the best-fit predictive model for the regeneration index made by multivariate analysis was as follows: Regeneration index (%) = 127.020 0.367 × effective diameter 1.827 × roundness
m + 47.371 × recipient body surface area (m
2) + 12.041 × log (recipient white blood cell count) (× 10
3/μL) + 18.034 (if the donor was female). …
