What is the purpose of Exercise tomographic thallium-201 imaging in patients with severe coronary artery disease and normal electrocardiograms?
The purpose of Exercise tomographic thallium-201 imaging in patients with severe coronary artery disease and normal electrocardiograms is to assess the presence of coronary artery disease, which can lead to myocardial ischemia and eventual heart attack. This imaging technique uses thallium-201 radioisotopes to measure the blood flow through the heart muscle. It is used to diagnose coronary artery disease when other diagnostic techniques, such as electrocardiography (ECG) and exercise stress testing, are inconclusive. The results of the imaging can help healthcare providers determine the best treatment plan for the patient. This can include lifestyle changes, medications, and/or surgical interventions.
