What Is a CT Scan?
CT, or computed tomography, is a noninvasive diagnostic imaging tool that uses X-rays and computerized 鈥渄etectors鈥 that rotate around the body. The X-rays pass through your body and are absorbed by the detectors. The scanner鈥檚 specialized computer system then creates detailed images of your organs, blood vessels, and soft tissues.
While a traditional X-ray creates a two-dimensional image, a CT scan captures a more detailed three-dimensional image. The advanced level of detail helps doctors view the inside of your body from multiple angles (also called slices).

CT Scan Versus MRI
You may wonder if your doctor will order a CT scan or a different kind of imaging, such as MRI (magnetic resonance imaging). Both techniques produce detailed pictures of organs and tissues inside the body. An MRI uses magnets and radio waves instead of X-rays.
When choosing which diagnostic scan to use, your doctor considers which body part needs imaging. Your doctor will use the details of your case to decide whether CT or MRI is right for you.
Do I Need a CT Scan with Contrast?
Depending on your symptoms and the body area that needs imaging, your CT exam may include contrast or dye. The contrast shows more details of disease in blood vessels and certain organs.
There are two types of contrast used in a CT exam:
- Intravenous or injection 鈥 The contrast substance contains iodine. This dense mineral absorbs the X-rays, creating more detailed views of internal structures.
- Oral contrast 鈥 You swallow a liquid containing barium, a naturally occurring metallic substance. The liquid mixture moves through the body and blocks X-rays from passing through organs like the stomach, intestines, and esophagus. A CT scan with a barium contrast produces highly detailed images to detect disease in these organs.
What Are the Side Effects of Contrast Dye after a CT Scan?
An allergic reaction to the contrast is rare, occurring in only 1 in every 1000 patients. Every patient at U of U 人妻中出视频 undergoes a thorough screening before diagnostic radiology exams. This evaluation ensures we know about preexisting medical conditions, allergies, or pregnancy.
