This study evaluates qualitative and quantitative SS EPI
diffusion-weighted imaging for assessment of
intrahepatic cholangiocarcinoma. Initial results
demonstrate high lesion conspicuity with approximately a
third of lesions showing a target appearance. ADC of
grade 3 tumors was lower than those of grade 2 without
reaching significance. These preliminary results suggest
that DWI is useful for cholangiocarcinoma detection,
however ADC quantification for assessing tumor grade
needs further validation.
