Correct!
1.  The chest CT shows that the nodule is stable

The left lower lobe nodule has remained stable, and no new surrounding opacities are evident, nor is cavitation seen. The repeat chest CT (Figure 6) was performed according to a solitary pulmonary nodule enhancement protocol.

Which of the following represents a correct statement regarding the characteristics and interpretation of this study? (Click on the correct answer to be directed to the 9th of 17pages)

1. The nodule shows enhancement ˃15 HU, which is indicative of malignancy
2. The value of the solitary pulmonary nodule lies in its ability to diagnose malignancy within a solitary pulmonary nodule when enhancement is identified
3. The subtraction image shows increased density suggesting enhancement
4. The nodule shows no evidence of enhancement of 4 post-contrast time points, suggesting a benign etiology
5. The study is non-diagnostic
