ADENOSINE MYOCARDIAL PERFUSION SCAN

About Adenosine Myocardial Perfusion Scan

Adenosine Myocardial Perfusion Scan is a specialized nuclear medicine cardiac imaging examination used to evaluate blood flow to the heart muscle. The test uses a radioactive tracer and gamma camera imaging along with adenosine, a medication that produces pharmacological stress when exercise-based stress testing is not suitable or when pharmacological stress is clinically indicated.

The examination can provide information about myocardial perfusion at rest and/or under stress conditions according to the prescribed cardiac imaging protocol.

What Does an Adenosine Myocardial Perfusion Scan Evaluate?

This examination evaluates blood flow to different regions of the heart muscle. It can help identify areas where myocardial perfusion is relatively reduced during stress or at rest.

The findings may help doctors assess the distribution of blood flow within the myocardium and correlate the results with symptoms, cardiac history and other investigations.

Why Is an Adenosine Myocardial Perfusion Scan Performed?

A doctor may recommend an adenosine myocardial perfusion scan when evaluation of coronary blood flow and myocardial perfusion is clinically required.

It may be considered for selected patients with suspected or known coronary artery disease, chest symptoms, abnormal cardiac investigations or when assessment of myocardial blood flow is required as part of a cardiac evaluation.

How Is an Adenosine Myocardial Perfusion Scan Performed?

A radioactive myocardial perfusion tracer is administered according to the prescribed nuclear medicine protocol. Adenosine is administered under appropriate medical supervision to produce pharmacological stress and increase coronary blood flow.

Gamma camera images are then acquired to evaluate the distribution of the tracer within the heart muscle. Depending on the prescribed protocol, imaging may include stress and resting phases for comparison.

Heart rate, blood pressure and the patient's clinical condition may be monitored during the pharmacological stress portion of the examination.

Preparation for Adenosine Myocardial Perfusion Scan

Preparation requirements can vary depending on the cardiac imaging protocol. Patients should follow the specific fasting, medication and other instructions provided by the nuclear medicine or cardiac imaging team.

Certain medications, including some medicines that affect heart rate or coronary blood flow, may need specific instructions before the examination. Patients should not stop any medication unless directed by their treating doctor or the medical team performing the test.

Patients should inform the medical team about heart disease, asthma or breathing problems, current medications, pregnancy or possible pregnancy, breastfeeding and other relevant medical conditions before the examination.

Benefits of Adenosine Myocardial Perfusion Imaging

Adenosine myocardial perfusion imaging provides functional information about blood flow to the heart muscle during pharmacological stress.

It can be useful when an exercise-based stress test is not appropriate or when pharmacological stress is specifically required. The results can complement other cardiac investigations when interpreted as part of a complete clinical assessment.

Understanding the Adenosine Myocardial Perfusion Scan Report

The report may describe myocardial tracer distribution during stress and rest, including areas of relatively reduced perfusion. The findings may be assessed for patterns that could be consistent with reversible or persistent perfusion abnormalities.

The results should be interpreted together with symptoms, medical history, ECG findings, cardiac imaging and other relevant investigations. The treating cardiologist or qualified specialist can determine the clinical significance of the findings.

Frequently Asked Questions

What is an Adenosine Myocardial Perfusion Scan?

An Adenosine Myocardial Perfusion Scan is a nuclear medicine cardiac imaging examination that evaluates blood flow to the heart muscle using a radioactive tracer and adenosine-induced pharmacological stress.

Why is adenosine used during myocardial perfusion imaging?

Adenosine increases coronary blood flow and produces pharmacological stress, allowing myocardial perfusion to be assessed without requiring exercise-based stress in appropriate patients.

Does an Adenosine Myocardial Perfusion Scan use radiation?

Yes. The examination uses a small amount of radiation from the myocardial perfusion radiotracer. Imaging is performed using a gamma camera according to the prescribed protocol.

Is adenosine myocardial perfusion imaging suitable for everyone?

No. Suitability depends on the patient's medical history, symptoms, medications and clinical condition. The referring doctor and medical team determine whether pharmacological stress imaging is appropriate.

How should I prepare for an Adenosine Myocardial Perfusion Scan?

Preparation varies according to the protocol and may include fasting and specific medication instructions. Patients should follow the instructions provided by the nuclear medicine or cardiac imaging team.

How much does an Adenosine Myocardial Perfusion Scan cost in Hyderabad?

The listed price for the Adenosine Myocardial Perfusion Scan at Focus Diagnostics is ₹28,000.
