Usefulness of combining 123I-FP-CIT-SPECT striatal asymmetry index and cardiac 123I-metaiodobenzylguanidine scintigraphy examinations for diagnosis of parkinsonisms

The combined use of striatal asymmetry index on DAT-SPECT and cardiac MIBG scintigraphy might offer useful clues for the differential diagnosis of the early phase Parkinson's disease from other parkinsonian syndromes.
