PET in Clinical Neurology.

PET in clinical neurology is most useful when complemented by meticulous clinical information and other investigational modalities such as MRI. Its major applications in clinical neurology are localization of seizure foci in potential candidates for epilepsy surgery, especially where other imaging findings are negative or inconclusive, and as an adjunct to clinical diagnosis in equivocal cases of dementia and Parkinsonian syndromes. When effective neuroprotective agents become available in the future, PET will have an additional role of identifying individuals at risk for developing neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease, as early treatment may prevent or delay development of the disease.
