title: [Diagnostic imaging of cancer of the pancreas and biliary tract].
abstract: Despite various kinds of diagnostic imaging modalities, most of the cancers of the biliary tract and the pancreas are advanced ones when diagnosed. Roles of ultrasonography and X-ray CT are emphasized as picking-up-a-cancer modalities. Flow-charts of diagnostic modalities in the diagnosis of cancers of the above organs are shown in order to avoid unnecessary examinations.
