FDG PET of HCC – pro

The detection rate of hepatocellular carcinoma in FDG (fluorodeoxy glucose)-PET is 50 to 70%, and it is inferior to that in ultrasonic testing and computed tomograph. Since dephosphorization enzymatic activity is high in hepatocellular carcinoma, especially of highly-differentiated type, the FDG is pumped out of the cells. Studies seem to peg sensitivity of FDG PET for detection of HCC at the unacceptable 50%, though it is higher for less differentiated cancers. This is lower than CT, MRI and even ultrasound11C-acetate PET is being studied for this cancer for this reason.

BASL Guideline says: “The usefulness of positron emission tomography (PET scan) is not established in HCC.”
