Computed tomography (CT scan) is an imaging procedure that makes use of x rays.
THE EQUIPMENT FOR THIS EXAMINATION:
The Istituto Radiologico Gortan uses a multi-slice CT scanner that can examine all body areas.
WHO PERFORMS THE EXAMINATION:
CT scan is performed by the radiologist. If a contrast agent is to be used, the radiologist is assisted by an anaesthesiologist. Radiologists are in charge of CT scan interpretation.
HOW IS THE EXAMINATION PERFORMED:
The patient is comfortably lying down on the examination table that moves through a short tunnel. Claustrophobia is not a problem. The duration of the procedure varies according to the body parts, but generally lasts 15 minutes.
There are no absolute contraindications to CT scan. There are contraindications concerning the use of ionizing radiation and its potential biological hazard for tissues.
There are contraindications to the use of intravenous contrast agents in (possibly) allergic patients. In this case, a desensitizing treatment is indicated to reduce the risk of serious allergic reactions. The patient has to notify any known allergy.
HOW TO PREPARE FOR THE EXAMINATION:
No preparation is envisaged for a CT scan without contrast agent. Instead, if a contrast agent is to be used, a preparative 6-hour fasting is required together with certain specific blood tests (creatinemia) prescribed by the General Practitioner.
