Abstract

Background: The new classification of progressive supranuclear palsy (PSP) subtypes necessitates identifying radiological biomarkers to support the clinical diagnosis.

Objective: The goals was to test if magnetic resonance imaging (MRI) morphometry, diffusion tensor imaging (DTI), susceptibility-weighted imaging (SWI), or [18F]fluorodeoxyglucose (^18FFDG)-positron emission tomography (PET) differentiates PSP subtypes from each other or Parkinson's disease (PD).

Methods: Midbrain/pons (M/P) area ratio, middle/superior cerebellar peduncle (MCP/SCP) width ratio, magnetic resonance parkinsonism indices (MRPI and MRPI2) and midbrain antero-posterior (AP) diameter were measured. Region of interest-based DTI, SWI, and ^18FFDG-PET analyses were performed.

Results: Four PSP subtypes (n = 85) and 24 PD were studied. MRI morphometry and DTI could differentiate PSP-Richardson syndrome (PSP-RS) from PSP-parkinsonism, PSP-postural instability, and PD (area under curve >0.7). SWI did not differentiate among PSP subtypes or PD. ^18FFDG-PET distinguished PSP from PD.

Conclusions: MRI morphometry and DTI differentiated PSP-RS from the other common PSP subtypes and PD and may be tested as a radiological marker of PSP-RS in larger studies.

期刊介绍： Movement Disorders Clinical Practice- is an online-only journal committed to publishing high quality peer reviewed articles related to clinical aspects of movement disorders which broadly include phenomenology (interesting case/case series/rarities), investigative (for e.g- genetics, imaging), translational (phenotype-genotype or other) and treatment aspects (clinical guidelines, diagnostic and treatment algorithms)
