Myocardial Perfusion Imaging (MPI) is a non-invasive imaging test that evaluates how well blood flows through your heart muscle. This advanced diagnostic tool can identify areas of the heart muscle that aren’t receiving adequate blood supply and assess the heart muscle’s pumping efficiency. MPI is commonly referred to as a nuclear stress test.
How Does MPI Work?
MPI involves the use of a small amount of radioactive material, called a radiotracer, which is injected into your bloodstream. This radiotracer travels to your heart and emits gamma rays, which are detected by a specialized camera to create detailed images of your heart muscle during rest and stress conditions.
Types of MPI
There are two main types of MPI: Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET).
Single Photon Emission Computed Tomography (SPECT):
Procedure: A gamma camera rotates around your body to capture images of the heart from different angles.
Usage: SPECT is widely used and provides high-quality images that help in diagnosing coronary artery disease and assessing heart function.
Positron Emission Tomography (PET):
Procedure: PET scans use a different type of radiotracer and a special camera to produce detailed images and measurements of blood flow.
Usage: PET scans are known for their higher resolution and accuracy compared to SPECT, making them particularly useful in more complex cases.
What Can MPI Detect?
MPI provides comprehensive information about your heart’s health, including:
- Blood Flow: Identifying areas with reduced blood flow, which may indicate coronary artery disease or blockages.
- Heart Muscle Function: Assessing how well the heart muscle is pumping and identifying any damage from previous heart attacks.
- Stress Response: Evaluating how your heart responds to stress, either through exercise or medication that mimics exercise effects.
The MPI Procedure
MPI is performed in a controlled medical setting and involves several key steps:
- Preparation: You will be given instructions on how to prepare, which may include fasting for a few hours before the test.
- Rest Imaging: The radiotracer is injected, and after a short waiting period, images of your heart at rest are taken.
- Stress Imaging: You will either exercise on a treadmill or receive a medication to increase your heart rate. Once your heart reaches a target rate, another dose of the radiotracer is injected, and stress images are captured.
- Analysis: The images are compared to evaluate blood flow differences between rest and stress conditions, helping to identify any issues.
