Accurate qualitative positioning and staging of periampullary cancers are of great value in guiding of treatment plan and evaluate postoperative outcomes. CT and MRI examination have made progress in the diagnosis of periampullary carcinoma. CT scan has a good spatial and temporal resolution, while MRI has a good tissue resolution. CT and MRI examination can be used for preoperative assessment of tumor resectability and invasion range, which is of certain value.
