胸部CT平扫在肺栓塞诊断中的临床价值

The clinical analysis of Chest CT scan in Pulmonary Thromboembolism

目的探讨胸部CT平扫在肺栓塞(PE)诊断中的临床价值。方法对55例PE患者均行胸部CT平扫检查,按栓塞面积分为大面积、次大面积PE35例和非大面积PE20例。结果本组患者CT表现中,非梗死性肺渗出影表现率较高,而典型楔形影、马赛克征等的表现率较低。大面积、次大面积PE与非大面积PE的各CT表现率比较差异均无统计学意义(P>0.05)。结论 PE的胸部CT平扫以非特异性改变为主,易误诊,但仍可为PE的诊断与治疗提供重要依据。

Objective To study the function of Chest CT scan in pulmonary thromboembolism, Methoos 55 cases in our hospital who were diagnosed with puhnonary embolism by CT pulmonary angiography （CTPA） were selected to explore the role of chest CT scan in the diagnosis of pulmonary embolism. Results In pulmonary embolism, non-infarct lung effusion was frequent,typical wedge shape and mosaic signs were rare, and there were no significant differences（ P 〉 O. 05 ）. Conclusion Through Chest CT scan based non-specific changes may easily lead to the misdiagnosis of pulmonary embolism,it still provide an important basis for the diagnosis and treatment of pulmonary embolism.
