A Positron Emission Tomography (PET) scan is a safe examination that provides doctors with unique imaging of the human body. Although there are similar tests such as an MRI or CT scan, the PET scan acquires imaging of the chemical and other changes in the brain that those other tests are unable to show. These incredibly detailed images allow a doctor to monitor an individual’s brain activity and can provide the ability to diagnose a problem, apply the best treatment, and see the effects of the treatment.
PET scans are commonly used for the evaluation and diagnosis of cancer, neurological disorders, and heart diseases.
A few of the neurological (brain) disorders that PET scans have been of diagnostic value are complex partial epilepsy, dementia, strokes, and brain tumors.
Complex Partial Epilepsy:
Numerous individuals are drug resistant in the US alone. For this reason, a CT scan and MRI are performed after required surgery. After the CT and MRI scan, a PET would help identify any epileptogenic foci.
PET scanning reveals a glucose use characteristic pattern in Alzheimer’s disease. However, PET imaging isn’t a diagnosis for Alzheimer’s disease and still requires other methods of diagnosis.
Tumors in the brain:
PET scanning is successfully able to grade brain tumors by monitoring their response to treatment to differentiate between the courses of recurrent tumors and radiation necrosis.
Although the use of PET imaging has been vastly used for monitoring multiple neurological disorders and has been validated as clinically useful, it’s role in further mental illnesses require more investigation.
When making use of a PET scanner in a facility, it is vital to make use of the best equipment to ensure that patients retrieve the right results through the machine while maintaining their comfort. GE PET scanners are some of the best pieces of equipment in the market for PET scanning procedures and ensure optimal results.
