Abstract

Multiple Sclerosis (MS) is considered a neurodegenerative disease that can cause multiple injuries within the Central Nervous System (CNS). MS can be diagnosed and qualitatively investigated with nuclear Magnetic Resonance (MR). In this study, a radiomics analysis is carried out considering 30 patients who underwent through MR studies consisting of T1-weighted (T1W), T2-weighted (T2W), Fluid Attenuated Inversion Recovery (FLAIR), and post-contrast administration T1W (T1WKS) images. Since radiomics features can vary greatly in relation to experimental extraction conditions, a first analysis is conducted by calculating the average percentage variations among features as the intensity bin size varies. A second analysis relates to the implementation of the predictive model based on the clinical outcome, namely the Expanded Disability Status Scale (EDSS) of MS. To this aim, the extracted features are reduced, selected, and then used to build the predictive model based on a machine learning algorithm, namely the Linear Discriminant Analysis (LDA). The k-fold strategy is used to split data into training and validation sets. Performance metrics of each model associated with the four MR images (T1W, T2W, FLAIR, and T1WKS) as the bin size varies resulted in optimal predictive values close to 80%.
