Association between focal spared area at the gallbladder bed in the fatty liver and intrahepatic efferent blood flow from the gallbladder wall was studied by color Doppler imaging in 72 patients with fatty liver, which was demonstrated as bright liver in the ultrasonograms (US).

The difference was statistically significant (p
