📖About Myocardial Perfusion Imaging
Myocardial perfusion imaging, commonly known as a nuclear stress test, evaluates blood flow to the heart muscle both at rest and under stress to detect areas of reduced perfusion caused by blocked coronary arteries. A radioactive tracer is injected and a gamma camera captures images that reveal how well blood reaches different regions of the heart. It is a key non-invasive tool for diagnosing coronary artery disease and assessing the extent of damage after a heart attack. The test also helps guide decisions about angioplasty, bypass surgery, or medical management.

Comprehensive health cover for individuals & families from ₹299/month. Cashless treatment at 14,000+ hospitals across India.
🔬How the Treatment is Performed
- 1Rest images are taken first after injecting a small tracer dose, followed by a stress phase using treadmill exercise or a pharmacological agent that simulates exercise for patients unable to walk. A second tracer dose is given at peak stress and images are captured again. The two sets of images are compared by a cardiologist to identify areas of reduced blood flow.
📝Pre-Treatment Preparation
- 1Consult a Nuclear Medicine specialist to confirm suitability for Myocardial Perfusion Imaging
- 2Complete all pre-treatment investigations as directed — blood tests, imaging, ECG, or specialist clearance
- 3Disclose all current medications, supplements, and allergies to your treating physician
- 4Fast (nil by mouth) for 6–8 hours if the treatment involves anaesthesia or sedation
- 5Arrange for a responsible adult to accompany you, especially for procedures requiring sedation
- 6Follow all specific pre-treatment instructions issued by your care team regarding diet or medication changes

⚠️Possible Side Effects & Risks
- 1Flushing or chest tightness from stress medication, mild radiation exposure, injection site bruising, rare arrhythmia during stress phase, headache from pharmacological stress agents
🩹Recovery & Aftercare
- 1No recovery time is needed and patients return to normal activity the same day. Increased fluid intake is recommended to help clear the tracer from the body faster. A cardiologist reviews the combined rest and stress images to determine if further intervention such as angiography is required.
Treatment Journey — What to Expect
Before Treatment
Pre-treatment workup, consent signing, and preparation as instructed by your care team. Baseline tests and imaging completed.
During Treatment
Myocardial Perfusion Imaging is administered over 2-4 hours (rest and stress phases). Vital signs monitored. Your specialist manages any immediate side effects.
