These gamma rays are then detected by a specialized PET scanner, creating detailed images that can be analyzed by medical professionals.
PET scans are widely used in the field of oncology to detect and monitor cancerous tumors. They can also be employed to evaluate heart and brain function, as well as diagnose certain neurological disorders.
Exploring Stress Tests
Now that we have a basic understanding of PET scans, let’s shift our focus to stress tests. A stress test, also known as a cardiac stress test or exercise test, is a procedure performed in combination with a PET scan to evaluate the heart’s function and blood flow during physical exertion. It helps identify potential heart-related issues that may not be apparent during rest.
During a stress test, the patient will typically walk or run on a treadmill while their heart rate and blood pressure are monitored. The level of intensity gradually increases, simulating the stress that would occur during physical activity. At the peak of the test, the radiotracer is injected, and the PET scanner captures images of the heart’s blood flow.
By comparing the PET scan images obtained during rest and exercise, doctors can assess any discrepancies in blood flow to the heart muscle. This information is vital in diagnosing conditions such as coronary artery disease, identifying blocked or narrowed arteries, and determining the overall health of the heart.
