CT

Computed Tomography Imaging

A CT scan, short for computed tomography and also known as a CAT scan, is a medical imaging technique that uses X-rays and advanced computer processing to generate detailed cross-sectional views of the body. MCR uses this especially valuable technology to display different types of tissues, including lungs, bones, soft tissues and blood vessels, all in a single scan.

Common Uses Of CT Scans

CT imaging plays a vital role in diagnosing and treating various medical conditions. At MCR, we frequently use it to:

  • Examine the chest and abdomen
  • Detect and manage cancer
  • Assist in treatment planning for radiation therapy
  • Help guide biopsies and other minimally invasive techniques
  • Evaluate surgical options
  • Diagnose spinal disorders and injuries affecting the skeleton, including the hands and feet
  • Assess injuries to the head, neck and internal organs such as the liver, spleen, and kidneys
  • Identify vascular conditions that could lead to stroke, kidney failure or other life-threatening complications

Preparing For A CT Scan

Our team is dedicated to your time and to your safety. For your convenience, we never want you to have to repeat a scan. To ensure accurate imaging, you can prepare for your scan in the following ways:

  • Wear loose, comfortable clothing on the day of your scan
  • Avoid wearing clothing with metal components like zippers or snaps
  • Remove any jewelry, glasses, hearing aids, dentures or hair accessories
  • Fast (avoid eating or drinking) as directed
  • Always tell your doctor or technologist if there is a possibility you could be pregnant

What To Expect During The Scan

Most CT scans last between 5 and 30 minutes. Patients will lie still on a table with pillows to keep you comfortable. During the test, the table will be moved into the opening of the scanner, which is circular. Please remain still during the scan. However, how much movement, and how noticeable it is, depends on the specific area our team is examining.

While you will be alone in the room, the technologist will monitor you via camera and be able to communicate with you on an intercom. Some facilities may allow a family member or friend to stay with you as long as they wear the protective shielding. Afterwards, you may be asked to wait briefly while our team reviews the images to ensure no additional scans are needed.

Will You Need Contrast?

Sometimes, we will need to use contrast material, which can help improve image clarity, allowing our team to more easily. Contrast material may be:

  • Injected through an IV
  • Taken orally
  • Delivered via an enema

Before receiving contrast, be sure to inform the medical team if you have allergies, particularly to iodine or certain medications, or if you have any medical problems such as asthma, diabetes or kidney, heart or thyroid conditions.

What You Might Feel During The CT Scan

CT scans are non-invasive and painless. However you might experience some mild sensations depending on the contrast:

If you need to drink a contrast liquid, it may have a chalky or slightly unpleasant taste, but it is usually easy to tolerate.

For colon studies, contrast may be administered rectally. This can cause a feeling of fullness or the urge to expel the liquid, but the discomfort is typically mild and brief.

Common side effects of IV contrast injections include a warm sensation or metallic taste that usually disappears quickly and mild itching skin or irritation, which can be managed with medication. Rare, more serious symptoms, such as swelling and difficulty breathing, require immediate action. If you notice these serious symptoms, tell your technologist immediately.

Before receiving contrast, be sure to inform the medical team if you have allergies, particularly to iodine or certain medications, or if you have any medical problems such as asthma, diabetes or kidney, heart or thyroid conditions.
