Computed tomography in dissection of the thoracic aorta.

ABSTRACT

Eleven patients presenting with thoracic aortic dissection were studied by computed tomography (CT). CT was usually performed with knowledge of the angiographic diagnosis. In eight cases, CT was definitive. This group included all six patients who received intravenous contrast material by bolus infusion. An algorithmic approach to patients with possible aortic dissection is suggested.
