Multidetector row helical CT of the pancreas: value of three-dimensional images, two-dimensional reformations, and contrast-enhanced multiphasic imaging.

Multidetector row helical computed tomography (MD-CT) scanning is performed for the evaluation of pancreatic tumors. Three-phase contrast study is performed using 2.5-mm collimation, and the images are reconstructed at 1.25-mm intervals. CT angiography and pancreatic duct images using two- or three-dimensional techniques are reconstructed from the volumetric data. MD-CT can perform multiphasic scanning rapidly with an optimal temporal window. CT angiography obtained with MD-CT can delineate peripancreatic vasculature with high spatial resolution and sufficient vascular enhancement. Pancreatic duct images can provide important information in assessing pancreatic disease. MD-CT has the potential to improve detection and preoperative assessment of pancreatic tumors.
