In this lecture from This is Why, Dr. Busti will make the identification of the heart borders and heart chambers on a chest x-ray easy. Dr. Busti will walk step-by-step through how to identify the cardiac silhouette, locate the heart borders, and understand where the right atrium, left atrium, right ventricle, left ventricle, left atrial appendage, and apex of the heart sit on a standard PA chest x-ray (CXR). You’ll see how to connect real heart xray images with the underlying heart anatomy. You’ll learn how to: - Identify normal heart borders on a chest xray - Recognize which heart chambers form the right and left heart borders - Understand where the right ventricle and left atrium actually sit on a CXR - Use the silhouette sign to localize lung pathology next to the heart - Apply a simple, repeatable approach to chest xray interpretation

In this lecture from This is Why, Dr. Busti will walk step-by-step through rib anatomy on a portable AP chest x ray (CXR), so you can quickly recognize posterior vs anterior ribs, assess inspiratory effort, and improve your overall chest x-ray interpretation skills. You’ll learn how to: Spot posterior ribs and anterior ribs on a standard AP chest x ray Use rib counting to judge film quality and inspiration Apply rib levels as landmarks when describing lung findings Avoid common mistakes when reading portable chest x rays in the ER, ICU, and inpatient units If you’re looking for a clear, visual guide to how to read a chest x ray, CXR for beginners, and how to count ribs on a chest x-ray, this session is for you. The goal = make medical education easy and clinically relevant.

Mastering chest X-ray positioning is the first step to safe and accurate chest X-ray interpretation. In this video, “How to Check Patient Positioning on a Chest X-Ray,” Dr. Busti walk through a simple, practical checklist so you can quickly decide if a CXR is good enough to interpret—or if positioning errors (rotation, poor inspiration, clipping) are misleading you.You’ll learn how to:Tell PA vs AP views and why it matters for heart size and mediastinumSpot patient rotation using the clavicles and spinous processesAssess inspiration on a chest X-ray (how many ribs is “good enough”?)Check centering and coverage so the lung apices and costophrenic angles aren’t cut offAvoid common mistakes that lead to false positives and missed pathologyThe goal = make medical education easy and clinically relevant.Chapter Table of Contents00:00 Chest X-Ray Positioning: Why It Matters for CXR Quality02:35 What Proper Chest X-Ray Positioning Actually Means08:00 Common Chest X-Ray Positioning Errors That Degrade Image Quality09:02 Key Anatomical Landmarks for Chest X-Ray Positioning11:10 How Poor Positioning Impacts Chest X-Ray Interpretation14:35 Applying Chest X-Ray Positioning Principles in Clinical Practice
