Myocardial Perfusion Scanning looks at blood flow patterns to the heart walls. The test is important for evaluating the presence and extent of suspected or known coronary artery disease, as well as previous injury to the heart from a heart attack.
You are given radioactive compound and a gamma camera is used to detect rays given off from this that collects in parts of the heart where there is good blood flow. This allows your cardiologist to plan any further treatment you may need. Myocardial Perfusion Scanning requires two scans. Firstly a stress test is used to evaluate changes in blood flow to the heart during maximal monitored exercise.
The radioactive compound is administered through a cannula in the arm which circulates to the heart, visualising regions of the heart that are not receiving adequate blood flow. After one minute, exercise is stopped and ECG and Blood pressure are monitored until they return to pre-test readings. An hour later, a further scan is performed in the Nuclear Medicine Department to assess the heart in its resting state. The two scans are compared to see if there is a difference in the blood supply to the heart at rest and at exercise.
