radiodense -
\white pattern solid fluid
infiltrate -
\any ill defined radio density
consolidation -
\solid white area
hyperlucency -
\extra pulmonary air
vascular markings -
\Lymphatic vessels lung tissue ( increased markings in CHF, decreased markings with
pneumothorax)
diffuse -
\spread throughout
opaque -
\fluid/solid
Fluffy infiltrates (Kurley A) -
\pulmonary edema (cardiogenic)
butterfly/bat wing -
