Kerley A And B Lines !!exclusive!!

Radiographically, Kerley B lines represent fluid or cellular buildup in the peripheral interlobular septa. When the pulmonary capillary wedge pressure rises above 15–20 mmHg—often due to left-sided heart failure—fluid leaks into these spaces, making them visible on an X-ray.

In summary, Kerley A and B lines are vital clues in thoracic imaging. Kerley B lines, in particular, serve as a reliable "red flag" for interstitial pulmonary edema, guiding clinicians toward a prompt diagnosis of cardiac or lymphatic distress. kerley a and b lines

Kerley A and B lines are important radiological signs on chest X-rays, indicating interstitial lung disease or edema. Accurate interpretation of these lines, in conjunction with clinical history and other radiological findings, aids in the diagnosis and management of various pulmonary conditions. Kerley B lines, in particular, serve as a
