Current diagnostic methods lack sufficient accuracy and consistency, highlighting the need for reliable segmentation tools integrated with advanced deep learning techniques.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose<\/jats:title>\n                    <jats:p>To develop and evaluate the multi\u2010stage severity assessment system (MSAS), a novel deep learning\u2010based framework designed for precise segmentation and accurate stratification of MD severity using 2D magnetic resonance imaging (MRI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>MSAS was developed using pixel\u2010level manual segmentation on MRI datasets from 189 patients (development cohort) and validated using an independent external test set of 70 patients. The framework integrates sequence\u2010level prediction and slice\u2010level segmentation, utilizing histogram of oriented gradients (HOG), support vector machine (SVM), YOLO\u2010V5, and gradient\u2010weighted class activation mapping (Grad\u2010CAM) techniques. Performance was rigorously evaluated using intersection over union (IoU), dice coefficient, accuracy, mean average precision (mAP), and area under the curve (AUC) metrics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>MSAS demonstrated strong performance, achieving an overall accuracy of 0.971 and an AUC of 0.995. Vestibular region detection yielded mean average precision (mAP) scores of 0.887 (internal set) and 0.877 (external set). For segmentation, dice coefficients were 0.940 (internal) and 0.941 (external), with consistent IoU values of 0.889 across datasets. Enhanced interpretability was achieved through slice attention maps and Grad\u2010CAM visualizations, effectively assisting clinical decision\u2010making.<\/jats:p>\n                  <\/jats:sec>\n
