CXR Learning Web Site

100 Normal Chest X-Rays

- developed by David G. Chu, MD -

Welcome! This website was created to help introduce medical students to chest radiology. One of the most difficult things to learn when first reading Chest X-Ray (CXR) films is what is "normal" and what is really "active disease." This website aims to help students become comfortable with accepting artifacts of blood vessels as "normal," with the hopes that students will then more easily identify "abnormal" signs of active disease.

We have assembled 100 "normal" Chest X-Rays that were given the Diagnosis of "No Active Disease" (NAD) at the Hospital of the University of Pennsylvania (HUP). By reading this series of Normal CXR, students will learn to appreciate the range of "normal" markings, the basics of CXR reading, and how patient age and sex influence differentials. Use the Navigation Bar to the right to either begin the Learning Module from the begining or jump to any case within the module.
