<P> Chest X-rays are frequently used to aid in the diagnosis of CHF . In a person who is compensated, this may show cardiomegaly (visible enlargement of the heart), quantified as the cardiothoracic ratio (proportion of the heart size to the chest). In left ventricular failure, there may be evidence of vascular redistribution ("upper lobe blood diversion" or "cephalization"), Kerley lines, cuffing of the areas around the bronchi, and interstitial edema . Ultrasound of the lung may also be able to detect Kerley lines . </P> <Ul> <Li> <P> Congestive heart failure x-ray . </P> </Li> <Li> <P> Congestive heart failure with small bilateral effusions . </P> </Li> <Li> <P> Kerley b lines . </P> </Li> </Ul> <Li> <P> Congestive heart failure x-ray . </P> </Li> <P> Congestive heart failure x-ray . </P>
