Research summary
Myocardial perfusion imaging is a standard test used to look at the blood flow to the heart muscle. It involves stressing the heart using either exercise on a treadmill or using drugs which mimic exercise. During the exercise, a small dose of radioactivity (Technetium-99m) is injected into a tap placed in an arm vein. Pictures (scans) are taken with special cameras that rotate around the patient but do not enclose or touch. The aim of this study is to compare the quality of images taken immediately after exercise with those taken at 40 minutes as is recommended in the summary of product characteristics (SmPC) for the radiotracer given. From preliminary studies, we have found that with treadmill exercise, there is sufficient clearance of the radioactive tracer from the liver to provide very good quality images.
