PET Scans – Useful in Treating Many Ailments
PET and CT scans are different from MRI in functionalities. PET Scans and CT scan is very influential in determining the spread and extent of malignancies when we compare them with full body MRIs. MRI provides the view of our internal organs in 3D formats but PET and CT scan combines the capability of nuclear imaging and also shows the internal organ's functional attribute. The doctors get helped in the determination and staging of malignancies.
During performing PET scans, a radiotracer, which is a radioactive matter, is inserted in the body and it gets accumulated around affected organs for examining purpose. The traces emit some gamma rays on the area and provide the details of the organ which is affected with its metabolic and chemical activities. The metabolic activity determines the concentration of the radioactive matter and it helps in identifying and staging of the exact tumor location.
PET Scans are very helpful in diagnosing some serious diseases and are very expansive. In the world, many countries have different rates of performing this type of scan. A full body CT scan costs one-third in the international medical tourism destination than what it costs in the countries like USA and UK. Many people needing PET scan come to these countries to save the money.
