Abstract

This article describes an approach to analyzing the distribution of intravenous contrast on chest computed tomography and illustrates the various pathologies and pitfalls that may be encountered by the imager, especially in the hospitalized patient. Understanding normal and abnormal distribution of intravenous contrast can be used as a clue to detect alterations in physiology and flow.

Keywords: Artifact; Contrast; Flow; Pulmonary embolism; Shunt; Tamponade; Thrombus.
