Angiography

Angiography is a medical imaging technique used to visualize the inside of blood vessels and organs, especially the arteries, veins, and heart chambers. It helps detect blockages, narrowing, aneurysms, or other abnormalities in the blood vessels. This test is often done using contrast dye and X-ray imaging, CT (CT Angiography), or MRI (MR Angiography), depending on the clinical requirement.
Angiography, also called an angiogram, is a diagnostic procedure that uses contrast dye and X-ray imaging to examine the arteries and veins in different parts of the body. It helps doctors see how blood is flowing through the vessels and whether there are any blockages, narrowing, or other abnormalities. This test plays a crucial role in diagnosing heart disease, stroke, aneurysms, and peripheral vascular disease.

Types of Angiography

There are several types of angiography based on the area being examined:

  • Coronary Angiography – to visualize arteries of the heart

  • Cerebral Angiography – to examine blood vessels in the brain

  • Pulmonary Angiography – to check arteries in the lungs

  • Peripheral Angiography – to assess blood flow in the limbs

  • Renal Angiography – to examine arteries in the kidneys

  • CT Angiography (CTA) – non-invasive, using CT scan and contrast

  • MR Angiography (MRA) – uses MRI technology and contrast dye

What Are Some Common Uses of the Procedure?

Angiography is commonly used to:

  • Diagnose blocked or narrowed arteries in the heart (coronary artery disease)

  • Detect aneurysms in the brain or other organs

  • Evaluate blood flow in stroke or mini-stroke (TIA) cases

  • Identify blood vessel damage from injuries

  • Assess conditions before or after vascular surgery

  • Plan treatment for tumors, especially if they affect blood supply

  • Monitor blood flow after organ transplants or surgeries

How Do I Prepare for My Angiography?

  • You may be asked not to eat or drink for 6–8 hours before the test

  • Inform your doctor if you’re taking medications, especially blood thinners or diabetes drugs

  • Tell your healthcare provider about allergies, especially to contrast dye, iodine, or shellfish

  • Wear comfortable clothing and remove any jewelry

  • You may need to arrange for someone to drive you home after the test

What Will Happen During My Angiography?

  • The procedure usually takes 30 minutes to 2 hours, depending on the area being examined

  • You will lie on an X-ray table, and a local anesthetic will be applied

  • A thin, flexible tube called a catheter will be inserted into an artery (usually in your groin or wrist)

  • Contrast dye will be injected through the catheter, and X-ray images will be taken

  • You may feel a warm sensation as the dye flows through your vessels

  • After the test, pressure will be applied to the insertion site to prevent bleeding

What Are the Reasons for an Angiography?

Doctors recommend angiography when they suspect:

  • Coronary artery disease (heart blockages)

  • Brain aneurysms or vascular malformations

  • Deep vein thrombosis (DVT) or pulmonary embolism

  • Poor circulation in legs (peripheral artery disease)

  • Kidney-related vascular issues

  • Trauma or injury affecting blood vessels

  • Planning for stent placement, bypass surgery, or angioplasty
