30 MRI and MRCP for Diagnosis and Staging of Pancreatic Cancer

摘要: Pancreatic cancer is a challenge for imaging. Close attention to technique necessary optimize the contrast between this type of tumor, which typically ill-defined, and normal-enhancing pancreatic parenchyma ability identify disease. Tumor best visualized on fat-suppressed T1-weighted images parenchymal phase dynamic gadolinium-enhanced imaging, but liver metastases venous involvement by tumor are seen portal enhanced imaging technique. Also important knowledge differential diagnosis cancer, includes chronic pancreatitis, lymphoma, metastases. Thin thick sections MRCP useful provide comprehensive overview biliary ductal anatomy evaluate intraductal pathology. The common hepatic artery, celiac superior mesenteric vein, splenic artery vein understand local staging can be well depicted with current 3D techniques. Issues in that need understood assessing extent circumferential arteries, patency structures, involvement. MRI also has very role identification metastases, several new developments such as specific agents have improved MRI’s accuracy regard.
