| 目的 探讨99Tcm-MAA动态-全身-局部肺灌注显像对原因不明呼吸困难的诊断价值。方法 收集因原因不明呼吸困难行99Tcm-MAA动态-全身-局部肺灌注显像的19例患者，以出院诊断为标准，分析患者显像结果。结果 共13例患者确诊为肺内分流，其中9例患者诊断为肝肺综合征，另4例患者包括1例遗传性毛细血管扩张症、3例肺内分流原因未明。所有患者均排除肺栓塞。结论 99Tcm-MAA动态-全身-局部肺灌注显像，可同时诊断或排除肺内分流及肺栓塞，可在临床推广使用。 |

| Objective To investigate the differential diagnostic value of 99Tcm-MAA dynamic-whole body-local lung perfusion imaging in unexplained dyspnea. Methods Nineteen patients with unexplained dyspnea underwent 99Tcm-MAA dynamic-whole body-local lung perfusion imaging. The imaging results were analyzed based on the discharged diagnosis. Results A total of 13 patients were diagnosed as intrapulmonary shunt, 9 of them were diagnosed as hepatopulmonary syndrome, the other 4 patients included 1 case of hereditary telangiectasia and 3 cases of intrapulmonary shunt were with unknown causes. All patients were excluded from pulmonary embolism. Conclusion 99Tcm-MAA dynamic-whole body-local lung perfusion imaging can simultaneously diagnose or exclude pulmonary shunt and pulmonary embolism, and can be widely used in clinical practice. |
