Abstract:
Objective To investigate enhanced CT scanning in differentiation of solitary pulmonary nodule and relationship between the degree and pattern of enhancement and vascularity. Methods 11 patients with surgically confirmed pulmonary carcinoma and 13 patients with inflammatory nodules and 6 patients with tuberculoma were studied with plain chest CT sean and enhanced scanning after injection of 100 ml iodinated contrast medium to observe the enhancement degree and pattern of the lesion before the surgery. Vaseularity of specimens of 11 carcinoma and 13 inflammatory nodules and 6 tuberculoma were examined pathologically and correlated with degree of enhancement. Results The pulmonary carcinoma and inflammatory nodules showed a significantly higher degree of enhancement than tuberculoma. But the carcinoma and the inflammation showed no differences in degree and pattern of enhancement. The degree of enhancement was positively correlated with the number of blood vessles. The vascularity of carcinoma and inflammation was far richer than that of tuberculoma. Conclusion The results suggested that the enhanced CT scanning are distinctively different between carcinoma and tuberculoma,whereas little different between carcinoma and inflammation. Vascularity of the lesion plays an important role in the manifestation of enhancement.
