PET scanning- demonstrate functions of tissue cells

There is a technique known as PET scanning which is frequently used in nuclear medicine as an imaging device, which depicts the basic physiological functions of the cells under the study, and at the same time it primarily focuses on metabolism.

It is basically recommended by the doctors to detect the symptoms of serious diseases such as-

• In detecting the symptoms of cancer and determining the expanse of spread of the tumor cells in the entire body of a human being.

• It also helps in noticing the functioning of the human brain and the heart along with analyzing the quality of blood flowing across these organs. It further supports to evaluate and study the effects of myocardial infarction and ischemia on the patient after cardiac surgery is being done.

• One more thing to notice is that imaging technology of this device is also used to make out the management protocol for various brain abnormalities, central nervous disorders and seizures.

You should be familiar with the philosophy of PET scanning as this imaging technique contains a radioactive material called the radiotracer is injected into the body, which accumulates around the organ which is under examination. It is the concentration of the radioactive material which depends upon the metabolic activity, and at last this process supports in detecting the location of tumor in the body.
