HCC = hepatocellular carcinoma.
The number in the parentheses represents the number of hepatic lesions.
*
Comparison in the number of exponential terms between the HCCs and the other hepatic lesions using the Mann-Whitney U test.
†
Comparison in the adaptive IVIM parameter between the HCCs and the other hepatic lesions with three exponential terms using the independent-sample t test.
