CT scans are used to examine different parts of the body. Depending on the medical need, specific types of CT scans are performed:
Head CT scan
Used to diagnose conditions related to the brain, such as stroke, head injuries and neurological disorders.
Chest CT scan
Provides detailed images of the chest cavity to detect lung infections, lung nodules, pulmonary embolism and vascular abnormalities.
Abdominal and pelvic CT scan
Helps identify issues in the abdomen or pelvis.
Spinal CT scan
Evaluates spinal injuries or abnormalities such as herniated discs, spinal fractors and degenerative diseases.
Cardiac CT angiography
A specialized CT scan to visualize blood vessels and detect aneurysms, blood clots and blocked or narrowed arteries.
Cardiac CT scan
Focused on the heart to diagnose coronary artery disease, heart valve issues and structural heart abnormalities.
Bone CT scan

Preparing for a CT Scan
- Wear comfortable, loose-fitting clothing; you may be given a gown to wear during the procedure.
- Leave metal objects, including jewelry, eyeglasses, dentures and hairpins, at home or remove them prior to your exam; you may also be asked to remove hearing aids.
- Do not to eat or drink for several hours before the exam, especially if a contrast material will be used.
- Women should inform their physician and the CT technologist if there is any possibility that they are pregnant or are breast feeding.
- To avoid delays, remember to bring a copy of your prescription.
If you are having a CT interventional procedure, a radiology nurse will call you prior to your appointment to provide you with instructions and answer all of your questions.
