A CT Peripheral Angiogram is a medical imaging procedure that uses X-rays and contrast material to visualize the blood flow in the peripheral arteries, which are the blood vessels that carry blood from your heart to your extremities, including your arms and legs. This test can help identify blockages, narrowing, or other abnormalities in these arteries, which can lead to conditions such as peripheral artery disease (PAD).
Before you undergo a CT Peripheral Angiogram, it's important to follow certain guidelines to ensure a smooth procedure and accurate results:

A CT Peripheral Angiogram can help identify a variety of conditions affecting the peripheral arteries, such as peripheral artery disease, aneurysms, arterial injuries, and blood clots. It can also be used to monitor progress after surgery to repair these arteries.
During a CT Peripheral Angiogram, you'll lie on a narrow table that slides into the CT machine. The contrast dye is then injected into a vein, usually in your arm. As the dye travels through your bloodstream, the CT machine will take images of your peripheral arteries.
The procedure typically takes between 30 minutes to an hour, but this can vary depending on the specifics of the procedure and the area being imaged.
The procedure itself is not painful, but you may feel a warm sensation or a slight pinprick when the contrast dye is injected.
After the scan, you should be able to return to your normal activities immediately. You'll be encouraged to drink plenty of fluids to help flush the contrast dye from your body.
Generally, you can expect to receive the results within a few days. However, this can vary depending on your healthcare provider and whether further analysis is needed.
Like all medical procedures, a CT Peripheral Angiogram does carry some risks, including a small risk of radiation exposure and an allergic reaction to the contrast dye. Your doctor will discuss these potential risks with you prior to the procedure.
Allergic reactions to the contrast dye used in a CT Peripheral Angiogram are rare but can occur. If you experience symptoms such as hives, itching, or difficulty breathing after your scan, seek medical attention immediately.
A CT Peripheral Angiogram is a valuable diagnostic tool that can provide vital information about the health of your peripheral arteries. By following the provided instructions and understanding the process, you can feel more confident and comfortable going into your procedure. It's always important to discuss any concerns or questions you may have with your doctor.
