摘要
目的探讨多层螺旋CT低剂量扫描在监测早期肺癌动态进展的价值。方法对300例早期肺癌患者密切随访,分析其普通CT及低剂量CT图像特点。结果 (1)在直径小于5 mm,5～10 mm及大于10 mm的早期肺癌诊断中,普通CT与低剂量CT诊断符合率间无统计学差异(P>0.05)。(2)随访过程中,31例病灶无明显变化,90例病灶径线变大。其中12例病灶出现转移。结论多层螺旋CT低剂量扫描能够早期发现肺癌病灶,对受检者辐射损伤小,具有较高的应用价值。
Objective To investigate the value of multislice spiral CT （MSCT） low dose scanning in the monitoring of dynamic progress of patients with lung cancer at early stage. Methods 300 patients with lung cancer at early stage were closely followed-up, and their ordinary CT and low-dose CT image characteristics were analyzed. Results 1. In the diagnosis of early lung cancer respectively for the diameter less than 5mm, 5-10mm and greater than lOmm, there was no significant difference between the ordinary CT scan and the low-dose CT scan diagnosis （P 〉 0. 05 ）. 2. In the follow-ups, there were 31 lesions without significant change, and 90 lesions became larger, 12 lesions of which had metastasis. Conclusion Muhisliee spiral CT scanning can relatively detect lung cancer lesions earlier and eanse smaller radiation damage.
