Kerley B Lines On X Ray [best] Page

The lungs are divided into small structural units called . These lobules are separated by thin walls of connective tissue known as interlobular septa . Normally, these septa are too thin to be seen on an X-ray. However, when they become thickened due to fluid accumulation (edema), lymphatic congestion, or fibrosis, they become visible as the distinct horizontal "B lines". Primary Causes and Clinical Significance

Kerley B lines can be caused by a range of conditions, including: kerley b lines on x ray

Kerley B lines are short, horizontal lines at the lung periphery, typically seen at the costophrenic angles on a chest X-ray. They are a sign of interstitial edema, which is the accumulation of fluid in the interstitial tissue of the lungs. These lines represent interstitial thickening and are often associated with various cardiopulmonary conditions. The lungs are divided into small structural units called
