Difference Between Angiogram and Angiography – Complete Guide

Heart disease is unfortunately one of the biggest health challenges in India today. Every year, millions of people are advised to undergo tests to check whether their heart arteries are blocked or not. And this is where terms like angiogram and angiography start showing up on doctor prescriptions. Most patients (and families) get confused — Are these two the same thing? Or different? Is one safer than the other? Understanding these words is not just about medical jargon, it’s about making informed decisions for your health and wallet. In this guide, we’ll break down the difference between angiogram and angiography, when each is done, how they work, and what you can expect if your doctor recommends one of them.

Understanding the Basics

What is an Angiography?

Angiography is basically the process or test that doctors use to look inside your blood vessels. A special dye (called contrast dye) is injected into your arteries, and then X-ray images are taken. This allows doctors to see if there are any blockages, narrowings, or other abnormalities in your blood vessels. It’s commonly done for the heart (coronary angiography), but it can also be performed for the brain, kidneys, or legs.

In simple words: angiography = the medical procedure.

What is an Angiogram?

Now here’s where the confusion usually starts. An angiogram is not another test, it is actually the result of angiography. Think of it like this: when you take a photograph, the action of clicking the camera is “photography” and the printed picture is the “photograph”. Same logic applies here — angiography is the action (test), and angiogram is the final image/report your doctor studies.

So, angiogram = the image or film produced after angiography.

Key Difference Between Angiogram and Angiography

To sum it up in plain language:

• Angiography: The medical procedure where a contrast dye is injected, and X-ray images are captured.

• Angiogram: The actual image(s) or report produced from that procedure.

Many Indian patients get mixed up because even some doctors casually interchange the two terms in conversation. But knowing the real difference helps you ask better questions and avoid misunderstandings when planning your treatment.

Types of Angiography in India

Coronary Angiography vs Coronary Angiogram

Coronary angiography is the procedure specifically used to check blockages in the coronary arteries of the heart. This is the most common form performed in India because heart disease is widespread. After the test, the set of images you get — showing the arteries and any blockages — is called a coronary angiogram.

In India, coronary angiography is often recommended if you have chest pain, shortness of breath, or high risk due to family history. The angiogram results help cardiologists decide whether you need lifestyle changes, medication, or more advanced treatment like angioplasty.

CT Angiography vs CT Angiogram

CT angiography is another version that uses advanced CT (computed tomography) scans instead of traditional X-ray fluoroscopy. It is less invasive because it usually doesn’t require inserting a catheter into the artery. However, the results — the CT angiogram — still show the same thing: a detailed map of your blood vessels.

In India, CT angiography is becoming popular in big cities like Delhi, Mumbai, and Bengaluru since it’s quicker, but it may not always be as detailed as conventional angiography for certain patients.

Angiography vs Angioplasty – Key Differences

What is Angioplasty?

Many patients in India confuse angiography with angioplasty because the words sound similar. But the two are very different. Angioplasty is not a test at all — it is a treatment. After a doctor identifies blockages through an angiography, they may recommend angioplasty to open up the blocked artery.

During angioplasty, a small balloon is inserted through a catheter into the blocked artery and inflated to push the plaque aside. In most cases, a stent (a tiny wire mesh tube) is also placed to keep the artery open permanently.

So while angiography helps doctors “see” the blockages, angioplasty helps “fix” them.

Angiography vs Angioplasty – Diagnostic vs Therapeutic

The easiest way to remember:

• Angiography → Diagnosis (to find out if there’s a problem).

• Angioplasty → Treatment (to repair the problem).

A lot of patients, especially in India, first go through angiography. If the results show severe blockages, angioplasty is performed either immediately or after a short gap depending on the situation.

Two Main Types of Angiography

Doctors usually explain angiography in terms of two broad categories:

1. Invasive angiography – where a catheter is inserted into the artery (usually through the wrist or groin).

2. Non-invasive angiography – usually CT angiography, where no catheter is needed, and imaging is done with a CT scanner.

Each has its pros and cons. Invasive angiography provides more accurate and clear results, but it involves a hospital procedure. Non-invasive angiography is easier, faster, and less discomfort, but sometimes not suitable for patients with irregular heartbeats or kidney issues (because of contrast dye).

When is an Angiography Recommended?

Symptoms and Risk Factors

In India, angiography is often advised if a patient has:

• Severe or recurring chest pain (angina).

• Shortness of breath.

• Dizziness or fainting spells.

• Strong family history of heart disease.

• High cholesterol, diabetes, or hypertension that isn’t well controlled.

Because lifestyle changes in India (fast food, sedentary jobs, stress) are causing heart issues at younger ages, doctors now recommend angiography for patients even in their late 30s or 40s if symptoms appear.

Doctor’s Recommendation

Usually, cardiologists suggest angiography if less invasive tests like ECG, echocardiogram, or stress test show abnormal results. It’s considered the “gold standard” for detecting artery blockages.

In private hospitals across India, it’s fairly routine. Some people even get same-day discharge after the test, while others may need to stay overnight if angioplasty is also performed.

The Procedure Step-by-Step

Before the Test

If your doctor has suggested angiography, you’ll usually be asked to fast for a few hours. Certain medications (like blood thinners or diabetes tablets) may need to be adjusted. The medical team will also check kidney function, since the dye used can sometimes affect it. Many patients feel anxious, but honestly, the procedure is far less scary than most people imagine.

During the Test

The test usually happens in a special room called the catheterization lab. You’ll be awake, but local anesthesia will be given at the spot where the catheter is inserted (often wrist or groin). The thin catheter is then carefully threaded up to the arteries. Once the dye is injected, X-ray images are taken. Some patients describe a brief warm sensation, but otherwise it’s painless.

After the Test

You may need to lie flat for a few hours if the groin is used. If the wrist route was taken, recovery is faster. The doctor will go through your angiogram images with you and explain the findings. If blockages are serious, they might recommend angioplasty immediately or schedule it later.

Risks and Safety

Is Angiography Safe?

Angiography is considered very safe, but like any medical test, it carries small risks. Some possible issues are bleeding at the catheter site, allergic reaction to the dye, or irregular heartbeats. In India, complication rates are quite low because the procedure is very common in big hospitals.

CT Angiography vs Conventional Angiography Safety

CT angiography has lower risk since it doesn’t involve a catheter, but radiation exposure is slightly higher. Also, in kidney patients or those allergic to contrast dye, doctors may prefer conventional angiography because it allows for more control.

Cost of Angiography in India

Cost Factors

The cost depends on several factors:

• Government vs private hospital.

• City (Delhi and Mumbai usually costlier than smaller towns).

• Type of test (conventional or CT angiography).

Average Cost Ranges

• Coronary angiography: ₹10,000 – ₹25,000 in most Indian private hospitals.

• CT angiography: ₹8,000 – ₹20,000, depending on the scanner and city.

Government hospitals are usually cheaper, sometimes as low as ₹2,000–₹5,000, but waiting times can be longer.

Alternatives to Angiography

Non-Invasive Tests

Doctors may first recommend ECG, echocardiogram, or a treadmill stress test. These are cheaper and simple, but they don’t give the same accuracy as angiography.

When Angiography Becomes Essential

If symptoms are strong or other tests are inconclusive, angiography becomes essential because it shows the real picture of blood flow.

FAQs – Answering Real Patient Questions

Is an angiography the same as an angiogram?

No. Angiography is the process, angiogram is the image/result.

What is the difference between angiography and angiogram?

Angiography = the procedure; Angiogram = the output image.

What is the difference between angiogram and angioplasty?

Angiogram is diagnostic, angioplasty is therapeutic (to fix the blockage).

What are the two types of angiography?

Invasive angiography and non-invasive angiography (like CT angiography).

Conclusion

Understanding the difference between angiogram and angiography is crucial, especially for Indian patients where heart disease is growing rapidly. Remember: angiography is the test, and angiogram is the result. Angioplasty, on the other hand, is a treatment done only if blockages are found.

These procedures are common, safe, and available across India — from big metro hospitals to smaller regional centers. If your doctor recommends one, don’t panic. The knowledge you’ve gained here can help you ask the right questions and feel more confident about the process.

Heart health is no joke. But the good news is — with timely angiography and the right treatment, many lives are being saved every single day.
