目的：探讨Ｘ线平片（ＣＲＸ）、放射性核素肺通气／灌注（Ｖ／Ｑ）扫描和肺动脉造影（ＣＰＡ）及ＤＳＡ，尤其前者在肺栓塞诊断中的作用。材料和方法：对经证实的１２９例肺栓塞病例的上述影像学表现进行分析。结果及结论：ＣＲＸ诊断ＰＥ的阳性提示率达７２％是一种非常实用的筛选手段；Ｖ／Ｑ扫描及ＣＰＡ／ＤＳＡ仍是诊断—确诊方法。
Objective: To investigate the role of X-ray plain film (CRX), radionuclide pulmonary ventilation / perfusion (V / Q) scan and pulmonary angiography (CPA) and DSA, especially in the diagnosis of pulmonary embolism. Materials and Methods: The above imaging findings of 129 confirmed cases of pulmonary embolism were analyzed. RESULTS AND CONCLUSION: The positive rate of CRX in diagnosing PE was 72%, which was a very practical screening method. V / Q scan and CPA / DSA were still the diagnostic-confirmatory method.
