【摘要】 目的评价放射性核素肺灌注显像在诊断急性肺动脉栓塞中的价值。方法对临床怀疑有急性肺动脉栓塞的25例患者进行了放射性核素肺灌注显像,同时行双下肢深静脉显像。结果25例患者中有23例出现不同程度的多发肺段血流灌注异常,其中41个肺段出现放射性缺损区,84个肺段出现放射性稀疏区。25例患者6例双下肢深静脉血栓形成。结论放射性核素肺灌注显像是诊断急性肺动脉栓塞的一种无创伤性的有效的检查方法。更多还原

【Abstract】 Objective To evaluate the clinical value of radionuclide pulmonary perfusion imaging in diagnosing acute pulmonary embolism.Methods Radioactive pulmonary perfusion imaging was performed in 25 patients clinically suspected for acute pulmonary embolism,meanwhile,imaging of deep veins of lower limb was taken.Results Multiple segments of abnormal blood perfusion were found in 23 of 25 patients,among them,radioactivity defects were found in 41 segments,radioactivity rarefied areas were found in 84 segments.Deep venous thrombosis was detected in 6 patients.Conclusion Radionuclide pulmonary perfusion imaging is a non-invasive and effective method in diagnosing acute pulmonary embolism.更多还原
