Angiography is a medical imaging technique used to visualize the inside of blood vessels and organs, such as the heart, brain, and kidneys. This procedure helps doctors diagnose and treat a variety of conditions related to the blood vessels, including blockages, aneurysms, and other vascular abnormalities. Through angiography, healthcare providers can access detailed images of blood flow, which are crucial for determining the best course of treatment for patients with vascular issues.
In this comprehensive guide, we will explore how angiography works, its various types, its applications in medicine, and what you can expect if you need to undergo the procedure.
How Does Angiography Work?
Angiography involves injecting a contrast dye (also known as a contrast agent or contrast medium) into the bloodstream, which makes blood vessels appear clearly on X-ray, CT (computed tomography), or MRI (magnetic resonance imaging) scans. These images are recorded in real time, allowing doctors to monitor blood flow and identify issues like blockages, narrowing, or abnormalities in the arteries or veins.
The procedure can be performed in different ways depending on the type of angiography being used:
- Traditional Angiography: This uses X-ray imaging and involves the insertion of a catheter into a blood vessel to inject the contrast dye.
- CT Angiography (CTA): A non-invasive method that uses a CT scan to capture images of blood vessels after the injection of contrast dye.
- MR Angiography (MRA): Uses magnetic fields and radio waves to create detailed images of blood vessels without the need for a catheter.
Types of Angiography
-
Coronary Angiography: This type is used to evaluate the blood vessels of the heart. It’s commonly used to detect coronary artery disease (CAD) or blockages that could lead to a heart attack.
-
CT Angiography: CT angiography (CTA) is particularly useful for visualizing blood vessels in various parts of the body, including the heart, brain, and lungs. It uses a CT scanner to produce cross-sectional images that allow doctors to assess the condition of blood vessels.
-
MR Angiography: Often used for brain, neck, and limb vessels, MR angiography (MRA) offers a non-invasive way to visualize blood vessels with no exposure to radiation.
-
Peripheral Angiography: This type focuses on the blood vessels of the limbs and is useful for diagnosing conditions like peripheral artery disease (PAD).
-
Cerebral Angiography: This is used to examine the blood vessels in the brain and diagnose conditions such as strokes or brain aneurysms.
Applications of Angiography
Angiography plays a key role in detecting and diagnosing several serious conditions, such as:
-
Heart Disease: Coronary angiography is essential for diagnosing heart conditions, particularly when it comes to detecting blockages in coronary arteries that supply blood to the heart.
-
Stroke: Angiography helps doctors identify blockages or abnormalities in the blood vessels leading to the brain, which are key contributors to strokes.
-
Peripheral Artery Disease (PAD): By visualizing the blood flow in the legs and arms, angiography aids in diagnosing PAD, a condition where blood flow is reduced in the peripheral arteries.
-
Aneurysms: Angiography helps in detecting weakened areas of blood vessels that may balloon out, leading to aneurysms.
What to Expect During an Angiography Procedure
If you’re scheduled to undergo angiography, here’s what you can expect:
-
Preparation: Before the procedure, you may be asked to fast for several hours. You should inform the medical team about any allergies (particularly to contrast dye) and any medications you’re currently taking.
-
The Procedure: During the procedure, a small catheter will be inserted into a blood vessel, typically in the groin or arm. The contrast dye will then be injected, and a series of images will be taken to visualize blood vessels.
-
After the Procedure: Once the procedure is complete, you’ll be monitored for a short period to ensure there are no complications. If you had a catheter inserted, you may need to lie flat for a few hours to prevent bleeding.
-
Recovery: Most people can resume normal activities within a day or two, depending on the type of angiography performed.
Risks and Benefits of Angiography
Like any medical procedure, angiography comes with its risks and benefits.
Benefits:
- Helps diagnose and treat various vascular issues.
- Provides clear images of blood flow, which can guide treatment decisions.
- Minimally invasive, particularly in the case of CT and MRI angiography.
Risks:
- Allergic reactions to contrast dye.
- Possible bleeding or infection at the catheter insertion site.
- Exposure to radiation, especially with traditional angiography or CT angiography.
Cost of Angiography in Delhi
The cost of angiography can vary depending on the type of procedure, the healthcare provider, and the location. In Delhi, India, the cost for a standard angiography procedure generally ranges from INR 25,000 to INR 50,000. However, CT angiography and MR angiography may cost slightly more due to advanced imaging techniques and equipment involved.
Here’s a breakdown of typical angiography costs in Delhi:
- Coronary Angiography: INR 25,000 to INR 40,000
- CT Angiography: INR 8,000 to INR 20,000
- MR Angiography: INR 12,000 to INR 35,000
The cost may also vary based on the hospital’s facilities, the doctor’s expertise, and any additional tests or services required.
