Positron Emission Tomography (PET)
Positron Emission Tomography (PET) is a medical imaging technique that helps doctors see how well the heart is working. During a PET scan, a small amount of a radioactive substance is injected into the patient's body. This substance emits positrons, which are positively charged particles. A special camera detects these emissions to create detailed images of the heart. PET scans show blood flow and metabolic activity, helping doctors diagnose conditions like coronary artery disease or assess heart function after a heart attack. It provides valuable insights that help guide treatment decisions.

Positron emission tomography (PET) is a medical imaging technique used to observe metabolic processes in the body. It involves injecting a small amount of a radioactive substance, called a tracer, that emits positrons. When these positrons encounter electrons in the body, they produce gamma rays. A special camera detects these rays and creates detailed images showing how organs and tissues are functioning. PET scans are especially useful for diagnosing conditions like cancer, heart disease, and neurological disorders, as they help doctors understand how well various parts of the body are working, not just their structure.
