title: Bolus-rapid infusion of contrast medium: simplified technique for optimal computed tomography pancreatography without use of dynamic scanning.
abstract: Optimal pancreatic computed tomography demands the use of both narrow beam collimation and high levels of intravascular contrast medium. Dynamic scanning with or without table incrementation has been advocated, but not all patients are amenable to prolonged breath holding, and tube cooling requirements may limit the study. In addition, repeat boluses usually must be administered to adequately image the entire pancreas. Enhancement may also be less than uniform. We describe a simple method of pancreatic scanning using bolus injection and pressurized rapid infusion of contrast medium that yields consistently high-quality scans demonstrating both pancreatic parenchymal and peripancreatic vascular enhancement in most patients. The method eliminates the need for dynamic scans in most cases and improves the speed of examination and quality of patient care in a busy computed tomography department.
