Abstract
Purpose: We wanted to evaluate the potential role of dynamic incremental computed tomography (CT) for making the diagnosis of malignant solitary pulmonary nodule (SPN) by investigating the dynamic enhancement patterns. Materials and Methods: Forty patients with presumed malignant SPN (diameter 16.2 seconds, and the average degree of maximum contrast enhancement was 66.422.17 HU. Most primary lung cancer showed rapid contrast enhancement with slow washout. The differences of the enhancement patterns among the histopathologic subtypes were not statistically significant (p > 0.05). Conclusion: Dynamic incremental chest CT was useful for making the diagnosis of malignant SPN that showed an established dynamic contrast enhancement pattern regardless of the histopatholgic subtypes.
