The increasing availability of multidetector CT scanners is having a major impact on imaging. This new technology acquires true volume data sets that can be easily manipulated with three-dimensional imaging to provide more information than classic axial displays. Nino-Murcia et al. [1] recently described the value of multidetector CT in generating data sets that were ideal for curved planar reformations of the pancreas and bile duct system. Similarly, these same volume data sets are ideal for generating CT angiographic maps of the key vascular structures that are potentially involved with tumor extension. The presence of tumor involvement of vessels will, in most cases, make the patient ineligible for curative resection [2]. The purpose of this pictorial essay is to show the unique capabilities of this technique in the evaluation of key arterial structures and its value in imaging patients with suspected or known pancreatic cancer.
