Positron Emission Tomography (PET) Scanners is a sort of imaging technique that is used to assess how your tissues and organs function at the cellular level. It entails injecting a radiotracer, a short-acting radioactive material that is absorbed by physiologically active cells. Then you are placed in a tunnel-like apparatus that detects and converts the emitted radiation into three-dimensional images. A PET scan can detect and assess the severity of a wide range of diseases, including cancer, heart disease, and brain disorders, by finding anomalies in a cell's metabolism.

Positron Emission Tomography (PET) Scanners offers a wide range of diagnostic applications, although it is usually done if your doctor suspects cancer or suspects that cancer has spread. It is commonly used to evaluate your heart's condition prior to bypass surgery, especially if other imaging tests are unclear. It is also frequently ordered if early Alzheimer's disease is suspected or to assess the brain prior to surgery to treat intractable seizures.
