What is a CT Angiogram?
A CT angiogram is a diagnostic imaging test that visualizes blood vessels and tissues.
During this procedure, dye is injected into the bloodstream to enhance the visibility of these structures.
A specialized CT scan, a type of X-ray, captures detailed images of the highlighted blood vessels and tissues.
Why Might I Need a CT Angiogram?
CT angiograms are commonly used to detect:
- Narrowed or Blocked Coronary Arteries: Essential for evaluating heart disease.
- Aneurysms: Irregular bulges in blood vessels.
- Atherosclerosis: Fatty plaque buildup inside blood vessels.
- Pulmonary Embolism: Blood clots widespread into the lungs.
How Does a CT Angiogram Differ from a Traditional Angiogram?
While both tests examine blood vessels, CT angiograms are less invasive.
- Traditional angiograms involve threading a catheter through a major artery to inject contrast dye and using X-ray fluoroscopy for imaging.
- In contrast, CT angiograms use an IV to administer the dye and rely on a CT scanner for imaging, making them less invasive and generally quicker.
What Should I Expect During and After the Test?
- Preparation: Follow your provider’s instructions, including fasting and avoiding caffeine before the test.
- Procedure: You’ll receive an IV for the dye injection and may have electrodes placed on your chest if undergoing a coronary CT angiogram. The scan itself is brief, lasting only a few minutes.
- Aftercare: You can usually resume normal activities on the same day. Stay well-hydrated to aid in flushing the contrast dye out of your system.
Are There Any Risks?
CT angiograms are generally safe.
However, if you have a history of allergic reactions to contrast dye or kidney issues, discuss these with your doctor, as they might require additional precautions or alternative tests.
Pregnant individuals are typically advised against CT angiograms due to radiation concerns.
