What is a cardiac silhouette?

Sir, exactly what is cardiac silhouette? Is it visible on chest x ray? What is its diagnostic use?

submitted by Abhinav from Parbhani, India on 8/12/2011


by Texas Heart Institute cardiologist, Benjamin Y. Cheong, MD    

Benjamin Y. Cheong, MDCardiac silhouette refers to the edge or outline of the heart that is visible on chest x-ray. This is what the radiologist sees on the chest x-ray when he interprets the film. Cardiac silhouette, itself, is not a pathology.
