急性肺血栓性栓塞的核素显像诊断与疗效判断(附10例报告)

Diagnosis and therapeutic evaluation of acute pulmonary embolism with radionuclide imaging

目的评价核素显像对急性肺血栓性栓塞的诊断与疗效评价的价值。方法对１０例临床确诊或可疑为肺栓塞的患者进行核素肺灌注、肺通气、肺血栓灶以及双下肢深静脉显像，４例与肺动脉造影或电子束ＣＴ结果对照。８例患者溶栓后复查肺灌注显像，２例患者复查肺血栓灶显像。结果肺灌注显像＋下肢深静脉显像对急性肺栓塞诊断的阳性率为１００％，与Ｘ线检查结果基本一致，溶栓后复查提示肺血流均有明显改善乃至恢复正常。结论核素显像对诊断急性肺栓塞以及判断疗效是一种准确、可靠的无创性手段。

Purpose To evaluate the diagnosis value of pulmonary radionuclide imaging for acute pulmonary embolism (APE) Methods 10 patients with suspected APE underwent pulmonary perfusion, ventilation, thrombus imaging and radionuclide venography, four out of them underwent pulmonary angiography and electron beam CT as well, in order to obtain more reference data All 10 patients were reexamined with pulmonary perfusion or thrombus imaging after thrombolysis Results The diagnostic positive rate of pulmonary imaging was 100%, which was accordant with the results of X-ray Pulmonary images after thrombolysis showed that the pulmonary blood flow perfusion was improved, even returned to normal Conclusions Radionuclide imaging is an effective and noninvasive method for diagnosing APE and evaluating therapeutic efficiency of thrombolysis
