CT - CAT Scan

Our state of the art CT system is specially designed to provide the lowest and safest radiation dose possible.

What Is A Ct Scan?

Also known as a "CAT scan," CT (Computed Tomography) combines multiple X-ray images to produce a two-dimensional cross-section view of anatomy with as much as 100 times more clarity than a conventional X-ray. CT imaging clearly shows soft tissue, like the brain, and dense tissue, like bone. The information gathered during a CT scan is processed by a computer and interpreted by a radiologist to diagnose or rule out disease. Some CT scans require a contrast medium, which can be given intravenously, orally, or both. The contrast agent will be able to highlight certain body parts to enable the radiologist to see any abnormalities. For example, CT scans of the abdomen and pelvis often require the patient to drink a barium-based liquid to outline the intestines for better viewing.

What Will The Exam Be Like?

You will be met by a CT technologist whose primary concern is your care and well-being. This technologist has completed a rigorous course of education and training and works under the close supervision of the radiologist to ensure the most accurate results from your examination. Before starting your CT exam, the technologist will explain the procedure to you and address any concerns you may have. Next, you will be gently positioned and secured on the scan table. It is important that you remain still because even the slightest movement during the exam can blur the picture and result in the need for repeated scans. You will hear humming as the equipment generates the images, and you will feel a slight movement of the table as it gently positions you for each scan. The technologist will have you in full view and constantly communicate with you through a two-way microphone.

How Do I Prepare For The Exam?
  1. Follow any specific instructions provided by your healthcare provider.
  2. Inquire if there are any dietary restrictions you need to follow before the CT scan.
  3. Inform your doctor about any allergies, health conditions, or medications you are currently taking.
  4. Wear comfortable and loose-fitting clothing, as you might be asked to change into a gown.
  5. Leave any jewelry, accessories, or metal objects at home, as they might interfere with the scan
  6. Arrive 15 mins early to complete any necessary paperwork or check-in procedures.
  7. If contrast dye is required, discuss any concerns or history of reactions with your doctor beforehand.
  8. Follow any specific fasting instructions, such as abstaining from food or drink for a specific period.
  9. Inform the technician if you are pregnant or suspect you might be, as some CT scans may not be safe during pregnancy.
