Chest Radiography: AP view
Kerley B lines (red arrows) are thickened horizontal linear opacities in the subpleural region, which meet the pleura at right angles.
Kerley A lines (yellow arrows) are longer lines coursing diagonally toward the hila in the inner half of the lungs.
Other findings:
1) Pulmonary venous congestions : visible at first intercostal space, vessels are more than 3mm in diameter.
2) Loss of clarity of major vessels: Perihilar haze. Undefined outline of vessels
This is due to leakage of fluid into the interstitium from pulmonary veins. Lymphatics converge to hilar and absorb fluid.
3) Pleural Effusion may be visible.
