Q
  1. A chest X-ray is performed in a Posteroanterior projection because -
A

The heart is closer to the film; thus it is smaller on the image.

31
Q
  1. Which reconstructions are ideal for the detection of pulmonary nodules on CT of the chest?
A

32
Q

33
Q
  1. What is located in the interlobular septas of the lungs?
A
