Magnetic Resonance Imaging in Parkinson's Disease

Steven J. Huber, PhD; Donald W. Chakeres, MD; George W. Paulson, MD; Rohit Khanna

Arch Neurol. 1990;47(7):735-737.


Abstract

• Magnetic resonance imaging was utilized to examine changes in the pars compacta associated with Parkinson's disease. We found a reduction in average width of the pars compacta in advanced- but not early-stage patients. Conversely, a significant difference in width (right minus left) was observed in early- but not late-stage patients. Width asymmetry may be a sensitive magnetic resonance imaging indicator for the early detection of Parkinson's disease when there is a predominance of unilateral clinical symptoms.
