| 目的探讨肺灌注显像判定肺心病患者肺动脉高压的程度及其意义。方法对28例肺心病患者及10例正常受试者行99mTc—MAA单光子发射计算机断层测定，测量肺灌注显像上、下肺野核素计数比值，同时应用超声检测收缩期三尖瓣返流压力阶差（the tricuspid valve regurgitation pressure gradient biggest，TRPG）估测肺动脉压（pulmonary artery pressure，PAP）作对照。结果肺动脉压力轻度升高时，肺上、下肺野核素计数比值高于正常对照组，组间存在有显著差异（P〈0．01），且肺上、下肺野核素计数比值与超声检测肺动脉压值呈正相关（r=0．82．t=7．31，P〈0．01）。结论肺灌注显像属先进的无创性技术，可应用来判定肺动脉高压的程度，联合心脏超声检测在肺心病的诊治上有重要意义。 |
