Heart Size
In an adult, a good quality film will show a normal cardiothoracic ratio of 0.5. Conditions causing a ratio >0.5 are cardiomegaly (dilation and hypertrophy), pericardial effusion, small lung volumes or pectus excavatum. However, a ratio of <0.5 cannot rule out heart enlargement, because the lungs could also be hyperinflated.
Calcifications
Evaluate for Calcifications
Calcified areas are dense. Look for these regions in valves, vessels (coronary arteries) pericardium and walls of the LV (aneurysm/posterior infarct). To find valves on a lateral film draw a lline from the carina to the xiphoid and then draw lines to divide the heart into thirds. The valves should fall at the junction of these lines.
