title: Improved cardiac iodine-123 metaiodobenzylguanidine accumulation after drug therapy in a patient with Parkinson's disease.
abstract: A 72-year-old woman with Parkinson's disease and autonomic dysfunction underwent I-123 MIBG cardiac imaging to study sympathetic neuronal integrity. This revealed a defect in the infero-posterior wall. Tc-99m sestamibi myocardial perfusion imaging revealed no abnormalities. On follow-up I-123 MIBG SPECT, the defect was less prominent and the parkinsonian symptoms were ameliorated by drug therapy. Cardiac I-123 MIBG imaging may be a promising new method for evaluating drug therapy in patients with Parkinson's disease.
