| 目的研究核素肺吸入、灌注显像对鉴别貌似炎症的急性肺栓塞及真正肺部炎症的价值。消除由于误诊耽误最佳溶栓时机的危险。方法对14例伴有胸痛、咳嗽或发热的急性肺栓塞及10例肺部炎症患者进行核素肺吸入灌注显像。以其损伤肺段当量数占被检肺段的百分比及其形态学改变对两种疾病在两种显像中的表现进行比较分析。并与X线胸片进行对比。结果急性肺动脉栓塞肺灌注显像示以肺段分布的异常放射性缺损区,损伤肺段当量数占被检肺段的27%;吸入显像基本正常,仅占0.4%.反之,肺部炎症则示吸入损伤明显,按或不按肺段分布,占被检肺段的40%;灌注显像占24%,部位与吸入像匹配,多为放射性减低。急性肺栓塞的X线胸片为正常、血管纹理减少或非特异改变；而肺部炎症则改变明显。结论急性肺动脉栓塞尤其貌似炎症者核素显像诊断价值较高。肺部炎症动态观察X线胸片诊断价值较高。但核素显像亦有能区别于栓塞的特点。肺栓塞合并炎症者,核素显像、特别是动态观察具有独特价值。灌注显像损伤范围可大于吸入影像损伤范围,病变呈以肺段形态分布的放射性缺损。 |

| Purpose Study value of differential diagnosis on acute pulmonary embolism of seemingly infection and real pulmonary infection with radionuclide pulmonary perfusion and ventilation imaging, in order to achieve the goal of proper therapy in time. Methods 14 Patients ill with acute pulmonary embolism with chest pain,cough or fever and 10 patients ill with pulmonary infection were tested by perfusion and ventilation imaging. The method of evaluation was to calculate percentage about damage equivelants of pulmonary segment. And take the radionuclide imaging compared with chest X ray film.Results On acute pulmonary embolism, damage equivelants of pulmonary segment were 27% in perfusion imaging and 0.4% in ventilation imaging.Perfusion and ventilation imaging were mismatch. Ventilation and chest X ray film were normal. Pulmonary infection damage equivelants of pulmonary segment were 24% in perfusion and 40% in ventilation imaging. Perfusion and ventilation were match almost. Chest X ray film was abnormal.Conclusion The valuable method about diagnosis on acute pulmonary embolism and pulmonary embolism accompanied with infection were radionuclide imaging and the valuable method about diagnosis on pulmonary infection was chest X ray film. |
