Abstract

Spiral CT permits the acquisition of a large volume of spatial information within a matter of seconds. If iodinated contrast media is rapidly administered intravenously and images are obtained during the first pass of the media through the arterial system, excellent visualization of the aorta and its branches can be obtained. Using a computer, two-dimensional (2D) images can be created in any plane (including curved planes) as well as three-dimensional (3D) images that can be viewed from any projection (spiral CT angiography). This article describes the method of spiral CT angiography, its limitations, and its application to such aortic diseases as congenital anomalies, dissection, aneurysm, trauma, infection, inflammation, thromboembolic disease, and postoperative complications. Guidelines for patient selection and the role of spiral CT relative to other imaging methods are discussed.
