X-Ray Showing Effect of Therapy
on Kerley's Lines

chf00027.jpg The left film shows Kerley B lines in the retrosternal area (red arrowheads) before treatment (left). With treatment of CHF (low sodium diet, diuretics, ACE inhibitors and digoxin), the patient improved and the Kerley B lines are no longer visible (film on the right). For extra credit, name the long line highlighted by the blue arrowheads.
