Area between the hepatic and heart curves of 99mTc-galactosyl-human serum albumin scintigraphy represents liver function and disease progression for preoperative evaluation in hepatocellular carcinoma patients

Background/purpose We developed software to calculate the pixels of interest in the area between the hepatic and heart curves (ABC) of 99mTc-galactosyl human serum albumin (GSA) scintigraphy. The aim of this study was to examine the accuracy of the ABC to evaluate liver function before hepatectomy.
