Due to the high cost, this advanced facility is only available in some best hospitals of renowned countries, PET scanning is known as position emission tomography scanning and it performs essential imaging function while being useful in detecting some deadly diseases such as cancer. It helps in determining the tumor cell spread by mapping the brain and heart functionality and analyzing blood flow in brain and heart. It also helps in the study and evaluation of ischemia and myocardial infarction effects on the sufferers after heart surgery. It determines management protocols of the brain abnormalities, disorder in the central nervous system and seizures. There is a functional difference between MRIs and PET/CT scanning. PET/CT scan is able to determine the malignancy spread and its extent whereas full body MRIs provide the internal organ view in the 3D formats but PET/CT scanning combines the ability of nuclear imaging apart from showing the functional attributes of the internal organs. It provides great help to the doctors in determining and staging of the malignancies. A radioactive matter called radiotracer is inserted in the patient’s body which then gets accumulated around the affected organs of the body for examining them while doing PET scan. The radiotracer emits gamma rays on the affected area and provides the affected organs details with the chemical and metabolic activity of the organ. The metabolic activity of the organ determines radioactive matter’s concentration and provides help in identification and staging of the tumor location. PET scanning is extremely helpful in the diagnosis of many deadly diseases and getting PET scan done is a costly thing. There are some countries in the world which are known as international destination for medical tourism which offer these types of scans at one third price of what costs in the developed countries like US and UK. People in search of affordable PET scan visit these countries to save their money.
