摘要
目的:探讨肺内孤立性结核球的16排螺旋CT动态增强的表现及临床应用价值。方法:对9例肺内孤立性结核球经CT进行增强前后对病灶进行连续动态扫描,层厚5 mm。结果:9例肺内孤立性结核球中8例强化不明显,其CT强化净值均小于15Hu,平均(10±5)Hu,时间密度曲线为平坦型;1例肺内孤立性结核球呈周边环形强化,其兴趣区(即中央部分)无强化,周边强化部分CT强化值大于15 Hu,平均(23±6)Hu。结论:病灶兴趣区的CT强化净值及时间密度曲线对结核球的诊断有比较重要的提示,16排螺旋CT动态增强扫描可以提高肺内孤立性结核球诊断的正确率,病灶轻度强化、不强化或包膜样强化可提示结核的诊断。
Objective：To explore the features and clinical application value of 16-slice spiral CT dynamic enhanced scanning in the patients with intrapulmonary solitary tuberculoma.Methods：CT strengthening continuous dynamic scanning was performed on the lesions in 9 cases of intrapulmonary solitary pulmonary tuberculoma with layer thickness of 5mm.Results：Among 9 cases,8 cases of aggrandizement were not obvious with the CT enhancement value of less than 15Hu,average（10±5）HU,the time density curves were flat;1 case showed a solitary tuberculoma demonstrating the peripheral ringlike enhancement,the interest area（the central part） had no enhancement,and the CT enhancement value in peripheral enhancement part was greater than 15HU,average（23 ± 6）.Conclusion：Spiral dynamic CT technique may improve the accuracy of diagnosing intrapulmonary solitary tuberculoma.The mild enhancement,no enhancement and/or capsule enhancement in lesions were suggestive of tuberculosis.
