A CT scan is a test that your doctor may order to view an area of interest in cross-section. A good analogy would be to think of your body as being a loaf of bread and every ‘slice' would be a picture on the CT exam. The test involves you lying on a table and moving in and out of a donut shaped hole. X-rays and computers generate the final images for a Radiologist to view or ‘read'.
Types of CT Exams
- Low Dose CT for Lung Cancer Screening
- Heart CT Calcium Score Scan or "Calcium Scoring"
- Sinus or Maxillofacial
- Head or Cranial
- Pelvic & Abdominal CT Scans
- Extremities such as arms, legs, hands, wrists; good for seeing a fracture or ‘break'
- Cardiac Coronary Computed Tomography Angiography (CTA)
Preparation for CT Exams
Oral and IV Contrast:
Depending on which test your doctor has ordered for you to have, we may have to give you an oral contrast to drink which will highlight the digestive tract on the CT exam. Sometimes in addition to this drink or instead of it, we will give you an intravenous contrast which will highlight the arteries and veins on the CT exam. Your doctor and the Radiologist, who is the doctor that reads the CT, will determine which contrast you will receive.
Not all CT Exams require preparation, but for those that do, we have provided instructions in the links above.
