On the left a patient with CHF.
There is an increase in heart size compared to the old film.
Other signs of CHF are visible, such as redistribution of pulmonary flow, interstitial edema and some pleural fluid.
On a supine film the cardiac silhouette will be larger due to magnification and high position of the hemidiafragms.
Exact measurements are not that helpful, but comparison to old supine films can be of value. #Clinical #Radiology #CXR #CHF #Exacerbation #Comparison #RadiologyAssistant
