The PET Scan involves the uptake and use of glucose that has been radioactively labeled and injected.
what is an MRI?
PET scans create finely detailed, three-dimensional images of the inside of the body.
The images can clearly display the body portion under investigation, along with any aberrant areas, and they can draw attention to how well-functioning specific bodily processes are.
To get even more comprehensive images, PET scans and CT scans are frequently combined. It's called a PET-CT scan.
Sometimes they are paired with an MRI scan (known as a PET-MRI scan).
Why are PET scans used?
Instead of just displaying the physical appearance of particular body organs, a PET scan can also reveal how well they are functioning.
When examining proven cases of cancer, PET scans are very useful for figuring out how much the cancer has spread and how well it is responding to treatment.
PET scans are occasionally used to aid in the planning of procedures like a brain operation for epilepsy or a coronary artery bypass graft.
They can also aid in the diagnosis of some disorders, such as dementia, that impair the brain's ability to function normally.
