What is involved and why?
The heart acts like a pump inside the body and requires an adequate blood supply to function well. This test assesses the changes to blood supply within your heart during rest and under stress. There are a number of reasons for your doctor to request this test such as; a heart attack, investigating shortness of breath, chest pain , heart rhythm irregularities, high risk factors for heart disease, analysing cardiac stents or preoperative risk assessment. Myocardial perfusion scan (MPS) is a two-part, non-invasive procedure where a safe amount of radioactive tracer (99mTc-MIBI) is injected into a vein in the arm and a gamma camera is used to scan the heart. The test demonstrates whether your heart muscle is receiving enough blood and also if your heart is pumping adequate blood supply to the rest of your body. The information from these results will assist your doctor in understanding the cause of your symptoms and providing the best course of treatment.
