多层螺CT 16层在肺动脉栓塞中的诊断价值

Multi-slice Spiral CT16 in Diagnosis of Pulmonary Embolism in Value

目的对比分析16层螺旋CT和单层CT的临床诊断差异。方法选取于该院2010年1月—2012年1月就诊的PE患者20例,将患者随机分为实验组和对照组,每组10人,实验组的患者接受16排螺旋CT扫描检查,对照组的患者接受飞利浦单层螺旋CE扫描检查,对检查结果进行回顾分析。结果实验组栓塞检出率为34.99%;对照组栓塞检出率为12.77%,两组差异有统计学意义(P<0.05);和单层CT相比,16层螺旋CT的三维重建图更为清晰地显示动脉血管的走向、分支等细节。结论 16层螺旋CT的临床诊断准确率高,为临床提供可靠治疗依据。

Objective Compare the differences of clinical diagnosis between 16-slice CT and single-layer CT. Methods Chose 20 PE patients in our hospital from January of 2010 to January of 2012, the patients were randomly divided into experimental and control groups, 10 in each group, patients in experimental group received the PHILIPS16-slice spiral CT scan whereas the patients in control group received the PHILIPS single layer spiral CT scan. The results were analyzed retrospectively. Results The em- bolism detection rates of experimental group and control group are 34.99% and 12.77% respectively, the difference is statistically significant, P〈0.05; 16-slice spiral CT 3D reconstructions clearly showed the direction of the arteries, branches, and other details compared with single layer CT. Conclusion The 16 slice CT is more accurate in clinical diagnosis of pulmonary embolism and is worthy of promoting in clinical use.
