In
patients undergoing orthotopic liver transplantation, preoperative MR imaging
characteristics in hepatocellular carcinoma were examined, including T1 and
T2 signal intensity, diffusion weighted imaging, and dynamic contrast
enhanced kinetics and their relationship with histopathologic grade was
assessed. DynaCAD, commercially
available software, was utilized to examine enhancement kinetics of each tumor.
Poorly differentiated HCCs had lower time to peak and higher rate of
enhancement. T1 hypointensity also showed correlation with poorly
differentiated tumors. No other qualitative or quantitative feature including
DWI was useful in predicting HCC differentiation.
