What Is a CT Scan? 

A computed tomography scan, commonly known as a CT scan or CAT scan, is a quick, painless, non-invasive imaging test that allows doctors to see inside your body. It uses advanced X-ray technology to produce images of blood vessels, internal organs, bones, and soft tissue.

The CT scan is used on areas such as the head, chest, abdomen, and pelvis. The images are taken at different angles and provide cross-sectional views of the scanned tissue. A CT scan is often required when an x-ray is inconclusive as it gives more detailed information.

What is a CT Scan Used For?

A CT scan is used to detect diseases and assess injuries. It examines patients with chronic symptoms such as abdominal pain, chest pain, or difficulty breathing. It also helps to identify various types of cancer.

The physicians at Cochise Oncology use CT scans in cancer treatment to show the size and shape of a tumor and pinpoint its location.

How is a CT Scan Performed?     

The CT scanner is a large donut-shaped machine with a tunnel in the middle. It has a motorized exam table that slides back and forth.

Before the scan, patients have to change into a gown and remove all jewelry. The CT scan may require contrast material, which is given orally or intravenously. The contrast material highlights specific tissues in the images. This makes it easier to distinguish select internal structures and improves the visibility of select blood vessels, organs, or tissues.

You will be positioned on the exam table and required to lie still as you move through the scanner. Several x-ray beams rotate around you during the scan taking pictures from different angles. A special computer program captures and processes the data and creates cross-sectional images of your body.

The images from the CT scan are sent to a radiologist for analysis. CT scans are quick, easy, and painless.

How Long Does a CT Scan Take? 

The length of the CT scan varies based on the area being examined. However, most exams take 20-30 minutes.
