| 目的 评价同层动态CT增强对直径≤2 cm肺癌的定性价值。方法 随机选择直径≤2 cm的肺癌23例,静注对比剂100 ml后,行肺结节的同层动态增强扫描。结果 直径≤2 cm肺癌增强后,除15 s外,不同时间段的CT值与平扫相比有明显统计学差异(P<0.05); 13例肺癌的三维重建中,血管形态异常以增多、增粗为主,占84.6%(11/13例)。结论 同层动态CT增强扫描有利于直径≤2 cm肺癌的定性诊断;动态CT增强与三维重建相结合,可提高直径≤2 cm 肺癌的定性准确率。 |

| Purpose To investigate the value of dynamic enhanced CT on peripheral bronchogenic carcinoma (diameter≤2 cm). Methods Single-location dynamic enhanced CT was performed in 23 peripheral bronchogenic carcinoma (diameter ≤2 cm)) after injection iodinated contrast 100 ml. Three-dimensional reconstruction of vessels were done in 13 patients. Results Compared with pre-enhancement scan, significant enhancement was found respectively at the series time except 15 second after injection of contrast material 100 ml in bronchogenic carcinoma (diameter≤2 cm). Three-dimensional reconstruction found there were increased number of vessels (11/13,84.6%). Conclusion Single-location dynamic CT is helpful to the differential diognosis of peripheral bronchogenic carcinoma(diameter≤2 cm). Single-location dynamic CT together with three-dimensional reconstruction of vessels can improve the dignosis of peripheral bronchogenic carcinoma (diameter≤2 cm). |
