The majority of misdiagnoses are related to the differential diagnosis of PD with atypical parkinsonian disorders (APD), such as multiple system atrophy–parkinsonian type (MSA-P), progressive supranuclear palsy (PSP), or corticobasal degeneration, as well as essential tremor (ET) and other forms of parkinsonism (drug-induced, vascular, functional).engMR imaging protocolParkinson's diseaseParkinsonian syndromesjournal article10.1002/mds.282041531-8257
