Learning objectives Lung-RADS is a quality assurance tool designed to standardize lung cancer screening CT reporting and management recommendations, reduce confusion in lung cancer screening CT interpretations, and facilitate outcome monitoring. Each exam should be coded 0-4 based on the nodule with the highest degree of suspicion. A negative screen is defined as categories 1 and 2; a positive screen is defined as categories 3 and 4. A negative screen does not mean that an individual does not have lung cancer. Lung-RADS...
Read more Background Nodule Measurement: To calculate nodule mean diameter, measure both the long and short axis to one decimal point in mm, and report mean nodule diameter to one decimal point. The long and short axis measurements may be in any plane to reflect the true size of the nodule. Volumes should be reported to the nearest whole number in mm³.Growth: An increase in mean diameter size of > 1.5 mm, within a 12-month interval. A ground glass nodule (GGN) that demonstrates...

No lung nodules OR Nodule with benign features:Complete, central, popcorn, or concentric ring calcifications OR Fat-containingLung RADS 2: Benign - Based on imaging features or indolent behavior Juxtapleural nodule: < 10 mm (524 mm3) mean diameter at baseline or new. Solid; smooth margins; and oval, lentiform, or triangular shape Solid nodule: < 6 mm (< 113 mm3) at baseline OR New < 4 mm (< 34 mm3) Part solid nodule:< 6 mm total mean diameter (< 113 mm ) at baseline.Lung RADS 3:...
Read more Conclusion The timing of follow-up imaging is from the date of the exam being interpreted. For example, 12-month screening LDCT for Lung-RADS 2 is from the date of the current exam. Also note that management of 4A lesions follows a stepped approach based upon follow-up stability or decrease in size. Category 3 or 4 nodules with additional imaging findings that increase the suspicion of lung cancer, such as spiculation, lymphadenopathy, frank metastatic disease, a GGN that doubles in size in 1...
