A computerized tomography scan is commonly known as a CT scan. It is an x-ray that views a specific part of your body from various angles and then combines these images to get a complete and comprehensive picture of internal organs, the brain, bones, muscles, blood vessels and nerves. Sometimes a contrast dye is injected to enhance whatever the radiologist and your doctor are looking at.
CT scans are commonly associated with detecting a stroke or brain injury, but it can be used in a number of different ways. CT scans can help:
A CT scan is often combined with a PET scan to see how a treatment, such as a cancer treatment, is working. This ensures that you or your loved one is getting the right treatment or procedure at the right time and to the right area of your body. Learn more about PET scans.
CTA stands for computed tomography angiogram. It is a non-invasive procedure that combines a CT scan with the use of a special dye injected into your bloodstream. An angiogram can also be performed without the use of a CT scan.
A CTA is used to look for any abnormalities in blood vessels located in your brain, heart, lungs, kidneys or other areas of your body. It is commonly used to find the location of an aneurysm, examine blocked or narrowed arteries, find blood clots, identify abnormalities in your brain or to evaluate a tumor. CTAs are commonly used to help diagnose a stroke or heart attack.
A CT or CTA scan is usually an outpatient procedure, which means it can be done at a Banner Health hospital, clinic or at select Banner Imaging locations.
Typically, very little preparation is needed but common preparation includes:
CT scans and CTAs are painless procedures. You will lie on a motorized table that moves through the scanner. You will be asked to remain as still as possible for the remainder of the scan and you may hear buzzing or whirring noises. Most scans take between 5-30 minutes.
For a CTA, you will receive an IV in your arm that will administer the contrast dye used as part of the scan.
Complications are rare. If a contrast dye is used, some people may have an allergic reaction, but it is unlikely. Pregnant women should not have a CT scan.
If you have any questions or concerns about your CT scan or CTA, be sure to talk to your doctor.
