Substantia Nigra Radiomics Feature Extraction of Parkinson’s Disease Based on Magnitude Images of Susceptibility-Weighted Imaging

Abstract: BackgroundIt is reported that radiomic features extracted from quantitative susceptibility mapping (QSM) had promising clinical value for the diagnosis of Parkinson’s disease (PD). We aimed to explore the usefulness of radiomics features based on magnitude images to distinguish PD from non-PD controls.MethodsWe retrospectively recruited PD patients and controls who underwent brain 3.0T MR including susceptibility-weighted imaging (SWI). A total of 396 radiomics features were extracted from the SN of 95 PD pati… Show more

“…The sensitivity and specificity of radiomics analysis for the diagnosis and progression prediction has been demonstrated in multiple diseases 18 20 . This approach is widely used in oncological applications, however it is less frequently used in neurological disorders, with few studies performed in PD 21 24 .…”

“…Intra-and inter-observer correlation coe cients (ICCs) were employed to quantify observer agreement in the extraction of radiomics features from the VOIs. [24] Then ROIs on SWI were linearly registered to individual T1WI and the quality of the registrations was manually assessed. Co-registration procedure was performed using advanced normalization tools (ANTs).…”

“…Parkinson’s disease (PD) is the second most common progressive neurodegenerative disease, affecting 1% of the population over 60 years ( Lin et al, 2020 ; Ren et al, 2021 ), and it is becoming more and more prevalent and associated with increased mortality ( Shu et al, 2021 ). The clinical symptoms of PD are heterogeneous, presenting a variety of motor symptoms (e.g., static tremor, bradykinesia, or rigidity) and non-motor symptoms (e.g., sensory and autonomic dysfunction, cognitive deficits, or disorders of mood) ( Kim et al, 2017 ; Amoroso et al, 2018 ; Lin et al, 2020 ; Sheng et al, 2021 ).…”
