A positron emission tomography (PET) scan is a pioneering imaging test that comes to your aid by revealing how the organs and tissues in your body are functioning. A PET scan in Patna makes use of a radioactive drug known as a tracer to put this activity on display. Time and again, a PET scan can carry out an accurate diagnosis of disease before it gets captured by means of other imaging tests.

· The tracer can be passed through your body by means of inhalation, swallowing, or injection depending on the particular organ or tissue that needs to be studied.

· The accumulation of the tracer is more in the areas of your body that have aggravated levels of chemical activity which, every so often, signify the spots where the occurrence of the disease has taken place.

Why is a PET scan done?
