  1. According to axial and sagittal T2-weighted images (T2WI) of the lumbar spine, the networked medical imaging remote Workstation AW 4.3 (GE Healthcare International) was used to import, interpret, and process DICOM images from MRI scans to categorize and obtain measurements of the following MRI parameters: protrusion diameter (PD), disc degeneration degree (Pfirrmann classification), endplate degeneration degree (Modic changes and total endplate score), and Schmörl’s node diameter (SND)
