Solid Indeterminate Pulmonary Nodules Less Than or Equal to 250 mm³: Application of the Updated Fleischner Society Guidelines in Clinical Practice

Table 2

2017 Fleischner Society management protocol for single solid indeterminate pulmonary nodules ≤ 250 mm³.

Nodule volume	Patient risk status
	Low risk	High risk
< 100 mm^3	No routine follow-up	Optional CT at 12 months
100-250 mm^3	Initial CT at 6-12 month, then consider CT at 18-24 months	Initial CT at 6-12 month, then CT at 18-24 months

High-risk patients with nodules < 100 mm³ with a suspicious morphology and/or an upper lobe location should repeat CT at 12 months.
