Preoperative assessment of liver function: a comparison of 99mTc-Mebrofenin scintigraphy with indocyanine green clearance test. Liver International 2004: DOI: 10.1111/j.1478-3231.2004.0901.x. © Blackwell Munksgaard 2004 The indocyanine green (ICG) clearance test is the most frequently used test for preoperative assessment of liver parenchymal function but has its limitations. The aim of this study was to investigate the correlation between ICG clearance test and the liver uptake of 99-Technetium-labelled (99mTc)-Mebrofenin (99mTc-Mebrofenin) as measured with hepatobiliary scintigraphy. Fifty-four patients were diagnosed as hepatocellular carcinoma ( n=9), hilar tumours ( n=20) and 25 patients with non-parenchymal tumours including colorectal metastasis ( n=15) and miscellaneous tumours ( n=10). One day prior to operation, hepatobiliary 99mTc-Mebrofenin scintigraphy was performed after intravenous injection of 85 MBq and the 15-min clearance rate of ICG (ICG-C15) was measured. The mean ICG-C15 was 86.86±1.19% (SEM). The mean 99mTc-Mebrofenin uptake rate was 12.87±0.52%/min. A significant correlation was obtained between 99mTc-Mebrofenin uptake rate by scintigraphy and ICG-C15 ( r=0.73, P<0.0001). The mean clearance capacity of the right liver segments (79.83±1.63, range 47.75–95.97%) was larger than that of the left segments (20.24±1.55, range 6.51–52.51%). 99mTc-Mebrofenin uptake rate as assessed by scintigraphy is an efficient method for determining liver function and correlates well with ICG clearance. At the same time, 99mTc-Mebrofenin scintigraphy provides information of segmental functional liver tissue, which is of additional use when planning liver resection. [ABSTRACT FROM AUTHOR]
