Thallium Stress Test

A Thallium Stress Test is a diagnostic procedure used to assess blood flow to the heart. It involves injecting a small amount of radioactive substance (thallium) into the bloodstream, followed by imaging to evaluate heart function during rest and stress.

This test detects coronary artery disease, assesses the impact of previous heart attacks, and evaluates blood flow within the coronary arteries. It helps healthcare providers identify areas of reduced blood flow or blockages.

Patients typically undergo physical exertion on a treadmill to simulate stress conditions. Alternatively, pharmacological stress agents may be used. A gamma camera captures images of the heart during rest and stress, providing valuable insights into myocardial perfusion.
