非钙化性孤立性肺结核瘤在胸片上很难与周围性肺癌鉴别。增强CT可以为鉴别良、恶性结节提供有益的信息。作者回顾性分析了过去7年间,11例手术切除并证实了的12个非钙化性结核瘤病灶,每个病灶直径均小3cm。11个结核瘤病灶做了动态增强扫描,另1个病灶做了静滴增强扫描。做CT动态增强扫描时,100ml碘对比剂以1～2ml/s的速率经肘前静脉输入,在注射开始后20～25s内,从肺尖扫描到肺底,层厚5～10mm,层距10mm,扫描时间1s,扫描床移动时间2s,在一次屏住呼吸时获得8帧层面的阁像,在第一次扫描20s后再做第二次扫描,
Noncalcifying solitary pulmonary tuberculosis is difficult to differentiate from peripheral lung on a chest radiograph. Enhanced CT can provide useful information for the identification of benign and malignant nodules. The authors retrospectively analyzed 11 surgically resected and confirmed 12 noncalcified tuberculoma lesions over the past seven years, each measuring 3 cm in diameter. 11 tuberculoma lesions were dynamically enhanced scan, the other one made an intravenous infusion enhancement scan. Do CT dynamic contrast-enhanced scan, 100ml of iodine contrast agent at the rate of 1 ~ 2ml / s by the antecubital vein input within 20 ~ 25s after the start of the injection, scanning from the lung apex to the bottom of the lung, layer thickness 5 ~ 10mm, layer spacing 10mm, scan time 1s, scan the bed movement time 2s, 8 frames at a time to hold the breath of the Court, in the first scan after 20s to do a second scan,
