computerized tomography

Computed tomography.

computed tomography

A diagnostic imaging technique in which multiple X-rays are taken from different angles in a single plane and a series of two-dimensional images (”slices”) of the different tissue densities—e.g., fat, muscle, bone, etc.—is constructed by computer. In contrast to conventional radiology, CT results in a 1000-fold increase in image resolution, and can pinpoint lesions < 2 mm in greatest dimension; dyes may be injected IV to increased resolution of abnormal tissue and blood vessels, or radiocontrast can be used for dynamic testing.
