According to the guidelines, follow-up imaging for patients with a single, solid, noncalcified nodule should occur as follows:

  • Less than 6 mm - No routine follow up; if high-risk, an optional CT scan can be considered in 12 months; this CT scan may be warranted based on suspicious morphology and/or upper lobe location of the nodule
  • From 6-8 mm - CT scan at 6-12 months, followed by consideration for a repeat CT scan at 18-24 months but, if high-risk, then proceed with a repeat CT scan at 18-24 months
  • Greater than 8 mm - Consider PET-CT, CT scan at 3 months, biopsy, or a combination of tests
