PET/TC and neurological diseases

The PET/CT methodology uses powerful magnetic fields and radioactive isotopes to evaluate the processes of the brain while a person is at rest or performing a specific activity. The PET/CT is therefore a fundamental test in neurological diseases, including Parkinson’s and Alzheimer’s.

Individual studies try to identify the underlying parts of the nervous system that are presumably involved only in certain mental and psychological phenomena (for example the parts of the brain that are active or inactive during different types of processes such as memory, learning, perception, and emotion).

The PET/CT programme for neurological diseases includes:

1. Differential diagnosis and early detection of dementia.

2. Localisation of epileptic foci in patients with refractory epilepsy for pre-surgical purposes.

3. Diagnosis and management of tumours of the central nervous system.

▪ Initial tumour evaluation

▪ Differential diagnosis between malignant and benign lesions

▪ Assessment of degree of malignancy, prognosis, and response to treatment; differential diagnosis of recurrence in brain tumours treated with radiotherapy and/or radiosurgery

▪ Early detection of the malignisation of benign tumours

▪ Study and assessment of various psychiatric disorders
