CT will also demonstrate signs of congestive heart failure.
On the image on the left notice the following:
Thickened septal lines due to interstitial edema
Subtle ground glass opacity in the dependent part of the lungs (HU difference of 100-150 between the dependent and non-dependent part of the lung).
Bilateral pleural fluid.
In a patient with a known malignancy lymphangitic carcinomatosis would be high in the differential diagnostic list. 
Ground glass opacity is the first presentation of alveolar edema and a precursor of consolidation. #Clinical #Radiology #CTChest #CHF #KerleyB #Kerley #Intersitial #Edema #IntersitialEdema #Septal #RadiologyAssistant
