In this lecture from This is Why, Dr. Busti will teach you how to quickly and confidently tell AP vs PA chest X-ray (CXR) views apart so you don’t get misled by magnified hearts or a widened mediastinum. In this video, we break down chest X-ray projection step by step and show you how to spot whether a film is AP or PA view just by looking at the image itself—skills you can use on your next shift or exam.

This teaching video is designed to help clinicians who want practical, bedside chest X-ray interpretation skills. We’ll connect the physics of X ray projection (AP vs PA) with real-world decisions, like when you can and cannot trust the heart size on a portable chest X-ray.

You’ll learn how to:
What AP and PA mean in chest X-ray views and why projection matters
How to recognize AP chest X-ray vs PA chest X-ray using simple visual clues
Why the heart often looks “enlarged” on AP portable CXR
How scapula position, patient posture, and inspiration help you identify the view
Common pitfalls in how to read chest X ray and avoid overcalling cardiomegaly

If you’re looking for chest X-ray basics, how to interpret chest X ray, or a concise refresher on frontal chest X ray positioning, this video will help build your foundation in radiology chest X ray and medical imaging education. The goal = make medical education easy and clinically relevant.
