Abstract: | Objective: TO evaluate the clinical value of MR multi-imaging technique in diagnosing and assessing the resectability of pancreato-biliary tumor. Methods The prospective diagnosis and resectability of 17 patients with suspicious pancreato-biliary tumors were evaluated. Surgical findings and pathologic results confirmed pancreatic adenocarcinoma in 11 cases, cholangiocarcinoma in 4, and non-neoplastic lesion in 2. MR multi-imaging protocol, including MR cross-sectional imaging, us cholangiopancreatography (MRCP ), and three-dimensional dynamic contrast-enhanced MR portography (3D DCE MRP), were performed in all patients. Results MR multi-imaging technique allowed-correct diagnosing 15 of 17 (88. 2% ) patients with pancreato-biliary tumors. The accuracy in detecting the range of tumor invasion was 64. 4%. The sensitivity, speificity, accuracy, positive, and negative predictive value of MR multi-imaging technique in assessing the resectability of pancreato-biliary tumors were 83. 3%, 77. 8%, 80. 0%, 71. 4%, and 87. 5%, respectively. Conclusion MR multi-imaging technique can not only improve the diagnostic ability of pancreato-biliary tumor, but also assess the surgical reartability of the tumor. With the fast development of MR techniques, the diagnosing and pre-operative assessment of aoncreato-biliary tumor may be more simplified and efficient by using the non-invasive "all-in-one" method. |
