Abstract

There is currently no definitive diagnostic test for Parkinson’s disease. A hypointense appearance of nigrosome-1 on MRI has been proposed as a biomarker for Parkinson’s disease. Current clinical practice involves a subjectively rating the appearance of nigrosome-1 on susceptibility-weighted images.1 The aim of the current study was to develop and test a simple method for quantifying nigrosome-1 in clinical settings. We hypothesised that area of nigrosome-1 hyperintense signal exhibits higher inter-rater reliability than subjective rating of nigrosome-1 appearance.
