CY Scan

Mandible and maxilla CT scan for implants

LThe Computerized Axial Tomography - more often referred to as a CT scan or CAT scan, consists in a non-invasive medical examination that helps physicians diagnose and treat disease.

A CT scan combines a special X-ray machine with sophisticated computers to produce multiple images or visualizations of inside of the body. These transverse images can then be reviewed on a computer screen or transferred to a recordable CD.

CT scans of internal organs, bones, soft tissues and blood vessels provide more clarity and reveal more details than conventional X-rays.

Through the use of specialized equipment and the knowledge to perform and interpret CT body scans, radiologists can diagnose disease easier, for example, cancer, cardiovascular diseases, infectious diseases in addition to musculoskeletal diseases and trauma.

How the test is performed

Patients lie down on a bed, which is slid into a cylinder-shaped tube that generates X-rays and turns around the patient.

It is painless and harmless. It does not cause claustrophobia or noise like the NMRI (nuclear magnetic resonance imaging). The radiology technician is in constant communication with the patient through an intercom system, and indicates the steps to follow.

Sometimes the use of radiological intravenous or oral contrasts is needed to see the functioning of certain organs. If you are allergic to these products, inform your physician beforehand (although you will be asked before being administered any contrast if you are allergic). As a result, you will need to sign a consent form accepting possible risks.

It is recommended that this test be performed on an empty stomach, although it is not strictly necessary- it depends on the type of CT scan you are having done. When your appointment is made, they will let you know. If you are going to have a digestive study performed, try not to eat food that produces gas the day before or foods high in fibre. When you make your appointment, you will be given a list of foods to prevent.


Preparation and advice

You should wear comfortable, loose clothes for the test. You will most likely be provided with a hospital gown to wear during the procedure.

Objects such as jewellery, eye-glasses, dentures and hair clips that could affect the CT images should be left at home or removed before the test. You might be requested to remove hearing aids or removal dentures. Women might be asked to remove their brassiere if it has wiring.

You might be requested to come on any empty stomach, which means not having eaten or drunk anything several hours prior, especially if a contrast liquid is going to be administered. You should inform your physician if you are currently taking or are allergic to any medication. If you are allergic to any of the materials of the contrast, or dye, your physician might prescribe medications to reduce the risk of an allergic reaction.

Furthermore, let your physician know if you have suffered any disease or recent illness or if you have a history of heart disease, asthma, diabetes, and kidney disease or thyroid problems.
