  • The 1 mm collimation gives the most accurate slice profile of lesion densitomery. This is therefore chosen to evaluate an SPN. Recent work suggests that degree of enhancement with IV contrast may be helpful, and will be the subject of a pending protocol.
  • 3D lung images are ideal for volume displays of the lung.
