Reduced 125I-meta-iodobenzylguanidine uptake and norepinephrine transporter density in the hearts of mice with MPTP-induced parkinsonism.
Uptake of (123)I-meta-iodobenzylguanidine ((123)I-MIBG) is markedly reduced in the hearts of patients with Parkinson's disease. Although the mechanism of this reduction is unclear, (12)(5)I-MIBG… Expand
