# Aperivue

> Aperivue builds free, educational radiology tools and content: RADS scoring calculators
> with structured, PACS-ready report generation, plus a medical-AI blog and open-source skills.
> Created by Yoojin Nam, M.D., a radiologist. These tools are for education and research only
> and are not medical devices; they do not replace professional clinical judgment.
