Advanced 3-D imaging for the evaluation of pancreatic cancer with multidetector CT
ABSTRACT Background. Pancreatic cancer remains the fourth leading cause of cancer-related death. Surgery is the only option for cure.
Multidetector computed tomography (CT) and advanced postprocessing techniques, can provide solutions for difficult problems
in diagnosing and staging disease, and can aid radiologists in communicating findings to surgeons and oncologists. Multiplanar
reformats can provide additional information on involvement of the portal vein, hepatic artery, and common bile duct. Maximum
intensity projection (MIP) images and volume rendered images can aid in identification of important vascular variants. MIP
images can show the relationship of tumor to the pancreatic duct or biliary tree. Curved reformatted images can show the relationship
of tumor to the pancreatic duct or vascular structures.

ABSTRACT: Since its introduction in the late 70's 3D imaging has assumed growing importance for the visualization of abdominal pathologies. Main clinical applications include the preoperative planning for resection of liver, pancreas and kidney tumors, living-donor liver and renal transplantation, and tumor radiofrequency ablation of liver and kidney. The advantages of 3D imaging are the exact visualization of vessels in areas with complex and variable vascular anatomy, demonstration of possible resection margins, and predicting operative risks, especially when dealing with complex or minimal invasive surgery. 3D imaging is an important visual aid for the surgeon in order to facilitate crucial decisions and to lower the operative risk. In future, 3D planning and simulation of operations will be become standard procedures. Therefore an efficient use of 3D imaging is not possible without a close collaboration between radiologist and surgeons.JBR-BTR: organe de la Société royale belge de radiologie (SRBR) = orgaan van de Koninklijke Belgische Vereniging voor Radiologie (KBVR) 90(6):467-74.
