Abstract:
ObjectiveTo investigate the diagnostic value of color Doppler ultrasound for peripheral intrahepatic cholangiocarcinoma (ICC).MethodsNinety- five patients with ICC which were confirmed histopathologically were retrospectively studied.The features on color Doppler ultrasound were analyzed.ResultsThere were 102 tumors which ranged from 20 mm× 20 mm to 130 mm× 100 mm in size.On gray-scale ultrasonic imaging,a large proportion of the tumors presented with inhomogeneous echo (n=75,73.5％), indefinite boundaries (n =70, 68.6％),and irregular shape (n=55,53.9％).On color Doppler ultrasonic imaging,most tumors had flow signals (75,73.5％) mainly in the shape of areatus,short- line and color-dot.Most flow signals had a resistant index greater than 0.6.Of the 102 tumors,thirty-seven (36.3％) were observed to produce streak hyperecho,twentynine (28.4％) slight attenuation in the rear and 22 (21.6％) unbilical depression.The coincidence rate with ultrasound was 84.2％(80/95). ConclusionsThe features of peripheral intrahepatic cholangiocarcinoma on color Doppler ultrasound are characteristic.To be able to appreciate these features is helpful to improve on the accuracy rate of ultrasound.
