摘要: 目的探讨增强CT扫描鉴别诊断肺内孤立性结节的意义以及强化程度与富血管度的关系。方法病理证实的肺癌11例、炎性结节13例、结核瘤6例,术前行CT平扫和以2.5 ml/s速率注入碘造影剂100 ml后增强扫描,观察病灶强化程度及强化形态,并计算以上30例病灶的手术切除标本的血管数目,与术前增强CT扫描强化程度做相关分析。结果恶性肿瘤的强化程度明显高于结核(P<0.01)。两者的强化形态也不同。恶性肿瘤与炎症强化程度无显著差异(P>0.05),两者强化形态亦无明显不同。观察手术切除标本,病灶强化程度与富血管度有相关性。结论CT平扫不能鉴别肺内孤立性结节的性质。增强CT扫描肿瘤与结核的强化程度及强化形态均不同,可以进行鉴别。但恶性肿瘤与炎性结节强化程度无显著差异,强化形态也相似,故不易鉴别。病灶强化程度反映其富血管度。 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.
