Correct: A — it does not distinguish Parkinson disease from the Parkinson-plus syndromes, since presynaptic dopaminergic loss is common to all of them. Option B is wrong because it is neither a screening test nor a monitor of treatment response; option C is wrong because it does separate Alzheimer disease, where binding is normal, from dementia with Lewy bodies, where it is reduced; option D is wrong because separating parkinsonism from essential tremor is its principal clinical use.
