Official Description

Myocardial imaging, positron emission tomography (PET), perfusion study (including ventricular wall motion[s] and/or ejection fraction[s], when performed); single study, at rest or stress (exercise or pharmacologic), with concurrently acquired computed tomography transmission scan

Common Language Description

A myocardial imaging, positron emission tomography (PET), perfusion study is a sophisticated non-invasive imaging technique designed to evaluate the heart's muscle perfusion and blood flow. This procedure utilizes radioactive tracers, known as nucleotides, which are injected into the patient's bloodstream. These tracers enable the creation of detailed three-dimensional images that illustrate how blood flows through the heart during various states of activity, such as at rest or under stress. The PET myocardial perfusion imagery (PET-MPI) not only assesses blood flow but also facilitates a wall motion study, which measures the pumping efficiency of the left ventricle and calculates the ejection fraction, or the volume of blood pumped out with each heartbeat. In cases of coronary artery disease or damage to the heart muscle, the perfusion of cardiac muscle may be compromised, leading to impaired function. The PET-MPI procedure is conducted in a specialized environment equipped with a gamma ray detecting scanner that integrates both PET and computed tomography (CT) capabilities into a single unit. During the procedure, the patient is positioned on a movable table, and an intravenous (IV) line is established for tracer administration. Electrocardiogram (EKG) leads are attached to monitor the heart's electrical activity, ensuring synchronization with the imaging process. The imaging process begins with the acquisition of CT data, followed by the injection of the radioactive tracer, after which the table moves through the scanner again to capture PET-MPI data. The uptake of the tracer varies in different tissues based on blood flow, allowing for the identification of narrowed coronary vessels, damaged tissue, and scar tissue, which manifest as distinct patterns and colors on the resulting images. The combination of PET and CT data enhances the accuracy of localizing areas of damage or disease by correcting for soft tissue attenuation using a CT map. Additionally, performing the PET-MPI/CT scan during stress—either through physical exercise or pharmacological stimulation—can yield further insights into cardiac function and perfusion dynamics.

1. Indications

The myocardial imaging, positron emission tomography (PET), perfusion study is indicated for the evaluation of various cardiac conditions. The following are the explicitly provided indications for this procedure:

  • Coronary Artery Disease - To assess the presence and severity of coronary artery disease, which can lead to reduced blood flow to the heart muscle.
  • Heart Muscle Damage - To evaluate areas of the heart that may have been damaged due to previous myocardial infarctions or other cardiac conditions.
  • Assessment of Ejection Fraction - To measure the ejection fraction of the left ventricle, which is crucial for determining the heart's pumping efficiency.
  • Wall Motion Abnormalities - To identify any abnormalities in the motion of the heart walls, which can indicate underlying cardiac issues.

2. Procedure

The procedure for a myocardial imaging, positron emission tomography (PET), perfusion study involves several detailed steps to ensure accurate imaging and assessment of cardiac function. The following outlines the procedural steps:

  • Step 1: Patient Preparation - The patient is positioned on a movable table within the imaging suite. An intravenous (IV) line is established for the administration of the radioactive tracer. Electrocardiogram (EKG) leads are placed on the patient to monitor heart activity throughout the procedure.
  • Step 2: Initial CT Data Acquisition - The first pass through the scanner is performed to acquire computed tomography (CT) data. This initial scan provides a baseline anatomical map of the heart and surrounding structures.
  • Step 3: Injection of Radioactive Tracer - Following the initial CT scan, the radioactive tracer is injected through the established IV line. This tracer is crucial for visualizing blood flow during the subsequent imaging phase.
  • Step 4: PET Data Acquisition - After the tracer injection, the table moves through the scanner again, this time with a slower transit time to capture the positron emission tomography (PET) data. This step records how the tracer is distributed in the heart muscle, reflecting blood flow and perfusion.
  • Step 5: Stress Testing (if applicable) - If the study is performed under stress, the patient may either exercise on a treadmill or bicycle until an optimal heart rate and blood pressure are achieved, or a pharmacological agent such as adenosine, regadenoson, dipyridamole, or dobutamine is administered to stimulate the heart. The scanning process is repeated to acquire both CT and PET data during this stress phase.

3. Post-Procedure

After the completion of the myocardial imaging, positron emission tomography (PET), perfusion study, the patient may be monitored briefly to ensure there are no immediate adverse reactions to the radioactive tracer or the stress testing. The results of the imaging will be analyzed to assess cardiac perfusion, wall motion, and ejection fraction. Patients are typically advised to resume normal activities unless otherwise instructed by their healthcare provider. Follow-up appointments may be scheduled to discuss the findings and any necessary further evaluations or treatments based on the results of the study.
