There are some functional differences between PET/CT scanning and MRIs. PET/CT scan determines the spread of malignancy and its extent but full body MRI provides an internal organ view in 3D format. PET/CT scan combines ability of nuclear imaging and also shows functional attribute of internal organs. It greatly helps doctors in determination and staging of malignancies. A radioactive matter, which is also called radiotracer, is put in the body of the patient which then accumulates around affected organ of the body for the purpose of examining the organ while getting PET scan done. The tracer then emits gamma rays on these affected areas and also provides affected organs details with their chemical activity and metabolic activity. The metabolic activity determines the matter’s concentration and helps in identifying and staging of tumor location.
PET scanning is helpful in diagnosing many types of fatal diseases and getting this done is a very costly in some countries. Some countries of the world are well known as international destination of medical tourism they offer this facility at one third of the price which is charged in developed countries. People looking for affordable PET scans go to these countries and save their money.
