摘　　要：为探讨肺灌注/通气显像对静脉注射毒品者肺栓塞的早期诊断,9例患败血症心内膜炎,急性脑梗塞患者用核素肺灌注、肺通显像进行观察,并与X线胸片、超声心动图结果进行对照,结果显示9例患者中,8例肺灌注呈双肺多节段稀蔬缺损,与通气显像不匹配,与通气显像不匹配,核医学诊断为急性肺栓塞1例溶栓治疗入病人肺灌注显像明显改善,与临床症状一致,从而证实灌注与肺通气显像联合运用对此类病人急性肺栓塞的早期诊断极有价值,并可做为溶栓治疗疗疗效的观察指标 另外也提示临床医师对静脉注射品者肺栓塞应有足够警惕.Purpose: To explore radionuclide lung scanning used for early diagnosis of acute pulmonary embolism in intravenous drug addicts. Methods: We performed observation with ventilation - perfusion lung scans and compared than with the findings of chest film and echocardiogram. Results:7 of 8 pativants appeared multiple scgmcntal less dense defects bilaterally on the lung perfusion imaging whieh mismatched with ventilation imaging and be diagnosed as acute pulmonary embolism in nuclear medicine. After treating with thrmobolytic therapy, lung perfusion imaging was markedly improved corresponding with clinical symptoms in one patient. Conclusion : Combination of ventilation - perfusion lung scan had great value for early diagnosis in patients with a-cute pulmonary embolism,and it also could be used as an index to observe the effect of thromboltyic therapy. We suggested that clinical physicias should be with caution in intravenous drug addicts to develop acute pul-monary embolism.
