Parkinson’s disease (PD) is a relatively common neurological disorder in the elderly. However, only 76% of patients considered clinically to have PD are confirmed to have PD after postmortem examination (Hughes et al., 1993). The most common atypical form of parkinsonism is multiple system atrophy (MSA) (Hughes et al., 1994). MSA is clinically characterized by a combination of parkinsonian, aut...
BACKGROUND AND PURPOSE: Progressive changes in the substantia nigra pars compacta and locus ceruleus of patients with Parkinson disease and Alzheimer disease visualized by neuromelanin MRI and cardiac postganglionic sympathetic nerve function on I-metaiodobenzylguanidine scintigraphy have not been fully evaluated. We compared the diagnostic value of these modalities among patients with early Pa...
BACKGROUND Heart Rate Recovery (HRR) reflects the capacity of the cardiovascular system to reverse the vagal withdrawal caused by exercise. Scintigraphy with metaiodobenzylguanidine (I(123) MIBG) evaluates innervation and cardiac adrenergic activation. The association of these two methods is not well established. OBJECTIVE To evaluate the association between HRR and washout rate (WO) of I(123...
BACKGROUND Left ventricular (LV) systolic dysfunction has been reported in humans with subarachnoid hemorrhage (SAH), and its underlying pathophysiology remains controversial. Possible mechanisms include myocardial ischemia versus excessive catecholamine release from sympathetic nerve terminals. METHODS AND RESULTS For 38 months, echocardiography and myocardial scintigraphy with technetium se...
UNLABELLED The purpose of this study was to investigate myocardial uptake of 123I-metaiodobenzylguanidine (MIBG) in patients with pure autonomic failure (PAF), which has pathologic features in common with idiopathic Parkinson's disease (IPD) and dementia with Lewy bodies (DLB). METHODS Six patients with PAF, 130 with IPD, 21 with DLB, 9 with corticobasal degeneration (CBD), 11 with progressiv...
