Correlation study of 18F-FDG PET/CT metabolic parameters, heterogeneity index, and microvascular invasion, and its nomogram potential in predicting microvascular invasion in liver cancer before liver transplantation.

The level of PIVKA-II was significantly elevated in the MVI-positive group, with a statistically significant difference ( P < 0.001); Differences in age, gender, alpha-fetoprotein (AFP), tumor size, number, differentiation, and staging did not reach statistical significance ( P > 0.05) (Table 1 ). 18 F-fluorodeoxyglucose PET/computed tomography metabolic parameters There are significant differences in SUVmax, SUVmean, SUVpeak, TLG, TLR, COV, and HI between the two groups ( P < 0.005).
