When the lungs look "too white" on a chest X-ray, there are only a handful of major possibilities. In this episode of Don't Miss That Radiology we introduce a simple framework to approach pulmonary opacities by asking one key question:

Is it blood, water, cells, or pus?

We'll cover

• Pulmonary hemorrhage (blood)
• Pulmonary edema (water)
• Pulmonary neoplasms (cells)
• Pneumonia (pus)

Practical imaging clues to help narrow the differential
A framework you can apply on exams and in clinical practice

We will also learn several signs including the silhouette sign, spine sign, air bronchogram sign, batwing sign and the marshmallow fluff sign

We'll finish it off with one of my favorite mnemonics for cavitary lesions. Spoiler alert the mnemonic is the word cavitys!!!

In this episode of Don't Miss That: Radiology 101 Podcast, we introduce the chest X-ray by focusing on some of the most important and potentially life-threatening findings every medical student, resident and clinician should recognize.

Topics include

• Misplaced lines and tubes
• Pneumothorax
• Pneumomediastinum
• Fre subdiaphragmatic air
• Pleural effusions

Rather than covering a complete chest X-ray interpretation method (coming soon), this episode highlights the critical emergencies that require immediate recognition. With July 1 and new interns starting, I thought this was timely. Learn practical radiology pearls that will help you identify these high yield findings with confidence.

Let’s learn the radiology of bowel obstruction and ileus. We will learn the rule of 3 for bowel pathology as well as the differential of small/large bowel obstruction. We’ll have fun while we learn some helpful signs and practice the law of burps and farts.
