🫁 ILD on Chest X-ray in 65 Seconds | High-Yield Radiology for FCPS, NEET-PG, USMLE & PLAB
Can you diagnose Interstitial Lung Disease (ILD) on a plain CXR in under a minute? 🩻⚡
This reel breaks down the 5 classic radiographic signs of ILD every medical student, house officer, and post-grad aspirant MUST know before their next exam or ward round:
✅ Bilateral lung volume loss
✅ Reticular (net-like) opacities
✅ Shaggy heart border sign
✅ Elevated hemidiaphragms (restrictive pattern)
✅ Esophageal dilatation from bilateral traction/fibrosis
⚠️ EXAM TRAP: Up to 10% of ILD patients have a completely NORMAL Chest X-ray! If your patient has progressive exertional dyspnea + bilateral fine Velcro crackles, don't let a normal CXR fool you — the next best step is always HRCT chest.
🧠 Quiz for you: Which ILD classically shows normal lung volumes or hyperinflation INSTEAD of restriction? Drop your answer in the comments 👇

Does blood flow to the heart occur in systole or diastole? This is one of the most asked questions in cardiac cycle physiology.

In this video, we explain when coronary blood flow occurs, why coronary circulation is different from other organs, and why most blood flow to the left ventricle happens in diastole.

You will learn:
• What is coronary blood flow and coronary circulation • Blood flow to heart in systole vs diastole • Why coronary arteries are compressed during systole • Why tachycardia causes myocardial ischemia • Difference between left and right coronary artery flow
This video is important for medical students, nursing students, USMLE, FCPS, and anyone studying cardiac physiology, cardiovascular system, and cardiac cycle.

Many students confuse systemic blood flow with coronary blood flow. Remember: Systemic organs get blood in SYSTOLE, but your heart muscle gets blood in DIASTOLE. Watch till the end to understand why.

How to measure heart diameter on Chest X-Ray? What does more than 50% heart diameter mean?

In this video, I will explain the Cardiothoracic Ratio (CTR) - the gold standard to diagnose cardiomegaly on a PA chest X-ray.

Normal Values:
Adults: CTR < 0.50 (50%
A CTR > 50% suggests cardiomegaly but does NOT confirm heart failure. It can be due to chamber enlargement, pericardial effusion, cardiomyopathy. Always correlate clinically and confirm with Echocardiography.
