Abstract This study, based on color Doppler and pulsed Doppler sonographic results of 13 cases with gallbladder carcinoma, eight cases of adenomyomatosis, and eight cases of tumefactive biliary sludge, shows that the presence or absence of blood flow signals helps in the differentiation between gallbladder carcinoma and tumefactive biliary sludge (84.6% sensitivity and 80.0% specificity). However, color Doppler sonography is still not fully capable of distinguishing all gallbladder carcinoma, and a further increase in Doppler sensitivity is mandatory for this purpose. Visualization of high-velocity blood flow within the lesion made gallbladder carcinoma more likely than benign tumor. In contrast, there was no difference in the resistive index between gallbladder carcinoma, adenomyomatosis, and normal subject groups, and the significance of the resistive index is a subject of future study.
