It is estimated that 472,000 people are living with dementia in Australia, with Alzheimer’s disease accounting for about two-thirds of cases.
Currently, there is no known cure for Alzheimer’s disease, and there is no definitive way to prevent it. However, researchers are exploring various methods for detecting the disease early on and slowing its progression. One of these methods is through the use of FDG PET CT scans.
Medicare have made the decision to offer a rebate for an FDG Study of the brain which is performed to assist with the diagnosis of Alzheimer’s disease. This rebate will now be available as long as the criteria are met, applicable not more than 3 times per lifetime.

FDG PET/CT scans are not limited to Alzheimer’s disease but can also help detect other forms of dementia.
It works by measuring the concentration of glucose in the brain to reveal how different parts of the brain are using energy. With different forms of dementia associated with reduced brain activity in specific parts of the brain, the scan can reveal patterns as to what may be causing the cognitive impairment.
In addition to identifying individuals at risk for Alzheimer’s disease, FDG PET/CT scans can also help researchers understand the underlying mechanisms of the disease. This can lead to the development of new treatments and preventative strategies in the future.
A FDG PET/CT scan is a non-invasive medical imaging procedure that uses a combination of positron emission tomography (PET) and computed tomography (CT) to produce detailed images of the body. FDG stands for fluorodeoxyglucose, which is a radioactive tracer that is injected into the body prior to the scan.
The FDG PET/CT scan usually takes about 30-60 minutes to complete. However, it does involve exposure to a small amount of radiation from the radioactive tracer. The risks associated with the scan are generally low, but individuals who are pregnant or breastfeeding should avoid the procedure unless absolutely necessary.
