Abstract Abstract: Objective: To evaluate the diagnostic value of dorsolateral putaminal abnormality on magnetic resonance imaging(MRI) for differentiating parkinsonism-predominant multiple system atrophy(MSA-p) from Parkinson's disease(PD). Methods: Teen patients with MSA-p, 20 patients with PD were included. All subjects were examined with 3.0T MRI using the conventional and diffusion-weighted protocol. Putaminal atrophy, hypointensity on diffusion-weighted imaging(DWI) associated with a slit-like T2-hyperintense rim on the dorsolateral putamen were evaluated in each item. Results: Putaminal atrophy was found in 60% (6 of 10) of the MSA-p group, in only 10%(2 of 20) of the PD group. Dorsolateral putaminal abnormalities were seen in MSA-p(n=8) group, and none in PD group. The slit-like T2-hyperintense rim and the hypointensity on DWI in the dorsolateral putamen were seen in 80%(8/10) of the MAS-p group, which is significantly higher than PD group(0/20). The specificity and sensitivity of the dorsolateral putaminal abnormality for distinguishing MSA-p from PD was 100% and 80%, respectively. Conclusions: The signal changes including slit-like T2-hyperintense rim associated with hypointensity on DWI in the dorsolateral putamen are specific signs for differentiating MSA-p from PD.
