PET CT scan is a modern era type of imaging tests which is utilized for investigating cases like Epilepsy, Cancer, Heart diseases as well as Alzheimer's Disease. PET scan stands for Positron Emission Tomography which shows the changes at the cellular level which cannot be revealed with the aid of MRI and CT scans. This type of imaging test ensures that the patient can resume with their daily routine after the procedure is completed.

It is also known as nuclear imaging, nuclear scans and radionuclide imaging. This technique is helpful in finding out the extent to which the cancer has spread in other words it helps in determining the stage of the cancer. The procedure is an outdoor one and with this, it can also be found out if the treatment is working effectively.

A PET scan can also be combined with a CT scan. It shows the areas that have increased cell activity. CT scan can provide more details about the same. It makes it easy for the doctors to point out the tumour. But there is more exposure to radiations in these tests.
