Preparation and Method
A CT scan of the chest does not require any special preparation or injection.
Usually, an appointment lasts approximately 10 to 20 minutes. However, less than 5 to 10 minutes are spent in the examination room.
First, patients lie on their back on a table. Then, the examination table moves through the CT scan for a few seconds. Several images from the apex to the base of the lungs are acquired during a single held breath. The use of contrast is not required. After the test, the radiologist evaluates the results to identify abnormalities in the lungs. Please note that the CT scan is a fully open device that does not cause claustrophobia.
