Although the survival rate of biliary tract cancer is high in the early stage when curative resection can be expected, the prognosis is poor due to the lack of subjective symptoms and difficulty in early detection. Therefore, diagnostic imaging plays an important role. However, if ultrasonography does not reveal any abnormality, or if ultrasonography is inadequate, CT or MRI(MRCP:magnetic resonance cholangiopancreatography)should be considered. In bile duct cancer, the dilated upstream bile ducts taper toward the hypoechoic mass(tapering)and the upstream bile ducts taper toward a hypoechoic mass(tapering). It is necessary to know the points of differentiation for similar lesions in bile duct cancer, because the treatment strategy may differ greatly depending on the imaging diagnosis.
