Liver function test by gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging with consideration of intrahepatic regional differences.

Background/aims: To accurately quantify liver function using gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA)-enhanced MR imaging.

Methodology: A total of 105 patients with suspicion of a hepatic tumor (Child–Pugh scores: 5 in 56, 6 in 26, 7 in 20, and 8 in 3) who underwent Gd-EOB-DTPA-enhanced MR imaging and an indocyanine green retention rate at 15 min (ICG-R15) evaluation were retrospectively analyzed. The hepatobiliary images were taken at 20 min after Gd-EOB-DTPA injection.
