How Do You Prepare For It?
Before preparing for the CT scan procedure, patients should know the possible risks involved. As the procedure exposes one to radiation, it can pose a risk of developing diseases such as cancer in the long run. But it is also worth mentioning that the exposure is very low – equivalent to 3 years of radiation from a normal environment. Pregnant women are advised to also take an alternative test instead of a CT scan to be on the safe side for their babies.
Before CT Scan
Patients are advised to wear loose clothing without zippers or metal clamps so that it will be easier for them to move around especially if the scan is just for a particular part of the body. Metal objects such as jewelry and belts are required to be removed to prevent them from interfering with the scan.
During CT Scan
Depending on the procedure, patients may be given contrast or a dye, which makes the scanned area clearer when examined. This can be administered via IV, orally, or via enema.
For the procedure, the patient lies on the bed of the CT scanner and is then moved into the gantry where the rotating x-ray detectors are found. Hearing a buzzing sound during the procedure is normal. It is advised to stay still during the procedure so that the images will not be blurry. It usually takes around 10 to 20 minutes to complete the scan.
