Chapter 86 Computed Tomography
Computed tomography is an invasive (when carried out with use of contrast dye) or noninvasive radiographic procedure that is performed to detect differences in tissue radiodensity. It is used for the entire body; for example, it provides a 360-degree view of the brain in 1-degree increments, giving an image of the intracranial structures and showing precise location of abnormalities. It is a diagnostic tool used in the assessment of various pathologic conditions. Serial evaluations can be performed because the amount of radiation is minimal.
NURSING INTERVENTIONS
