Role of Nuclear Stress Tests in Assessing Heart Function and Blood Flow

A nuclear stress test is a medical procedure that helps doctors evaluate the blood flow to the heart and assess its overall function. It is a non-invasive test that uses a small amount of radioactive material, called a tracer, to produce images of the heart during rest and exercise. This test is often recommended for patients who may have underlying heart conditions or are experiencing symptoms such as chest pain or shortness of breath.

During a nuclear stress test, the patient is injected with a radioactive tracer, usually through a vein in the arm. The tracer is then absorbed by the heart muscle and emits gamma rays that can be detected by a special camera. The patient is then asked to undergo activities that mimic exercise, such as walking on a treadmill or receiving medication that simulates the effects of exercise. The camera captures images of the heart at rest and during exercise, allowing doctors to compare the blood flow and function of the heart under different conditions.
