16层螺旋CT低剂量肺部体检的临床应用价值

Clinical value of low-dose lung screening with 16-slice CT scanner in physical examination

目的:探讨16层螺旋CT小毫安低剂量肺部体检的临床应用价值。方法:运用16层螺旋CT扫描速度快,覆盖面积广,可设小毫安低剂量肺部普查的有利条件,对114例受检者行肺部扫描,扫描条件为120 kV,20～50 mA,并进行标准(std)与肺模式(lung)2种方式重建。结果:114例受检者中,发现病变41例。结论:16层螺旋CT小毫安低剂量肺部普查值得推广。

Objective To evaluate the value of low-dose lung screening with 16-slice CT scanner in physical examination. Methods Lung screening was performed in 114 cases with a 16-slice spiral CT scanner. The scan parameters were 120KV, 20-50mA. The reconstructive modes were standard mode and lung mode. Results 41 cases with lung diseases were detected with low-dose 16-slice spiral CT. Conclusion Low-dose 16-slice spiral CT is good for lung scanning in physical examination.
