Aurora: Open-Access Web Application for Structured Neuroradiology Report and Score Calculation

Aurora (https://aurora-report.com/) is an open-source Web application that introduces structured, standardized reporting for neuroimaging, currently focused on dementia and movement disorders. Developed by and for radiologists and neuroradiologists, Aurora provides a stepwise workflow to support evaluation and reporting. It includes validated atrophy scales such as medial temporal lobe atrophy, global cortical atrophy, entorhinal cortex atrophy, and Koedam posterior atrophy, as well as a systematic approach to describe small vessel disease based on Standards for Reporting Vascular Changes on Neuroimaging, version 2 criteria. Each section offers literature-based guidance and annotated examples for scoring. The platform features built-in calculators for atrophy and movement disorder metrics, including midbrain and pons measurements, midbrain-to-pons ratio, Magnetic Resonance Parkinsonism Index (MRPI), and MRPI version 2.0. Aurora generates structured reports in English (US) or Portuguese (PT). To our knowledge, it is the first freely available platform to unify standardized reporting and calculation for dementia and movement disorders.
