This is a diagnostic imaging method that uses X-rays to produce cross-sectional images of the body in the transverse (lateral) plane (and, to the extent that positioning allows for certain specific organs, also in the longitudinal and lateral planes). During the examination, one or more contrast agents may be required to distinguish between or highlight various organs in the body. These may include the intravenous (into a vein) injection or intracavitary (into an organ’s cavity) administration of iodine-containing compounds, or the oral and/or rectal administration of barium sulfate compounds.
During the examination, the patient must lie still on the CT scan table. A CT scan typically lasts approximately 5–10 minutes, depending on the specific body region being examined or the nature of the condition being investigated.
During the examination, the patient may hear a noise caused by the CT scanner. The patient will pass slowly through the opening (gantry) of the CT scanner. Additionally, during some examinations, the patient will be asked to hold their breath at various intervals while X-rays are being taken.
Following the CT scan, the patient may resume their normal daily activities.
