CT扫描对肺栓塞的影像诊断价值

The value of CT scan on diagnosis of pulmonary embolism

目的探讨CT扫描对肺栓塞(PE)的影像诊断价值。方法将PE患者26例作为观察组,另选择同期26例健康体检者作为对照组,2组均行CT扫描检查,以肺动脉血管造影检查为金指标,计算CT扫描检测的敏感度,比较2组栓塞指数。结果 CT扫描与肺动脉血管造影诊断PE的敏感度比较差异无统计学意义(P>0.05)。观察组栓塞指数为(55.3±19.8)%高于对照组的(20.9±10.6)%,差异有统计学意义(P<0.05)。结论 CT扫描速度快、敏感、无创,对肺栓塞早期诊断有一定价值。

Objective To evaluate the va/ue of CT scan on diagnosis of pulmonary embolism（PE）. Methods 26 cases patients with PE were as observation group, the same period 26 cases of healthy persons were as control group, two group underwent CT scan, pulmonary angiography was the gold standard to calculate the sensitivity of CT scan detection, compared embolism index of two groups. Results CT scan and pulmonary angiography in diagnosis of PE showed no significant difference （ P 〉 0.05 ）. Embolism index of observation group [ （ 55.3±19.8 ） % ] was greater than that of control group [ （ 20.9 ±10. 6） % ], the difference was statistically significant （ P 〈 O. 05 ）. Conclusion CT scan in diagnosis of PE is fast, sensitive, noninvasive. On early diagnosis of PE has some value.
