Diagnostic accuracy of Magnetic Resonance Parkinsonism Index in differentiating progressive supranuclear palsy from Parkinson's disease and controls in Indian patients.
Abstract
An assessment of the sensitivity and specificity of magnetic resonance (MR) imaging measurements of midbrain, pons, middle cerebellar peduncles (MCPs), and superior cerebellar peduncles (SCPs) and MR Parkinsonism Index (MRPI) in differentiating progressive supranuclear palsy (PSP) from Parkinson's disease (PD) and controls was performed. The correlation of these MR imaging measurements with the duration and severity of disease in the Indian patients using the PSP rating scale (PSPRS) was also performed.
