If your cardiologist has recommended an MPI scan, you're likely looking for detailed information on what the test is, how it works, and where to get it done in Bangalore. This guide will walk you through everything you need to know about the Myocardial Perfusion Imaging (MPI) scan, its purpose, procedure, cost, and the best centers offering it in the city.
What is an MPI Scan?
An MPI (Myocardial Perfusion Imaging) scan, also known as a nuclear stress test or cardiac perfusion scan, is a non-invasive imaging test used to assess the blood flow to the heart muscle. It helps doctors evaluate:
Coronary artery disease (CAD)
Areas of the heart with poor blood supply
Heart function after a heart attack
Effectiveness of angioplasty or bypass surgery
How Does the MPI Scan Work?
The test uses a small amount of radioactive tracer (like Technetium-99m or Thallium) injected into the bloodstream. A gamma camera then captures images of the tracer in the heart muscle during rest and stress conditions (either through exercise or medication that simulates exercise).
Types of MPI Scans
1. Stress MPI Scan (Exercise or Pharmacological) – Assesses heart function under stress.
2. Rest MPI Scan – Shows how the heart is functioning when the body is at rest.
3. Two-Phase MPI Scan – Combines both rest and stress phases for comparison.
Preparation for MPI Scan
Before the Scan:
Avoid caffeine and certain medications 24 hours before the test.
Do not eat or drink (except water) for 4–6 hours prior.
Wear comfortable clothes and shoes if an exercise test is being conducted.
Inform your doctor if you are pregnant, diabetic, or asthmatic.
During the Scan:
The procedure takes around 2–4 hours depending on whether it's a single or two-phase scan.
You may walk on a treadmill or receive medication to stimulate your heart.
The radioactive tracer is injected, and the gamma camera takes detailed images of your heart.
Cost of MPI Scan in Bangalore
The cost of an MPI scan in Bangalore typically ranges from ₹7,000 to ₹15,000, depending on:
Whether it is a single-phase or dual-phase scan
The hospital or diagnostic center
If a pharmacological agent is used for stress induction
Some hospitals may also offer packages or accept insurance coverage for cardiac evaluations.
Why Choose an MPI Scan?
An MPI scan is highly effective in:
Detecting hidden heart issues
Guiding treatment decisions like angioplasty or surgery
Monitoring the progress of heart disease
Preventing sudden cardiac events in at-risk individuals
Final Thoughts
An MPI scan is a critical diagnostic tool for evaluating heart health, especially if you're experiencing chest pain, breathlessness, or have a history of heart disease. In Bangalore, you have access to some of the best nuclear medicine and cardiology centers equipped with the latest technology and experienced professionals. Always consult your cardiologist to choose the right center and understand what to expect before and after the scan.
