Overview

A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.

CT

Computed tomography (CT) and magnetic resonance imaging (MRI) have complementary roles in the diagnosis of CNS neoplasms. The speed of CT is desirable for evaluating clinically unstable patients; it is superior for detecting calcification, skull lesions, and hyperacute hemorrhage (bleeding less than 24 hours old) and helps direct differential diagnosis as well as immediate management.
