作者描述了CT在诊断和治疗肺栓塞中的临床应用和经济价值。并与肺动脉造影和通气灌注扫描进行了比较。作者收集20例CT诊断为肺栓塞的患者,年龄20～80岁,平均63岁,男女各10例,其中13例原有肺部疾患,7例有恶性病变,4例有血管疾病,除3例外均有呼吸困难和胸痛症状。CT扫描前,11例行肺通气灌注扫描,其中6例诊为“肺栓塞可能性大”,4 The authors describe the clinical application and economic value of CT in the diagnosis and treatment of pulmonary embolism. And compared with pulmonary angiography and ventilation perfusion scan. The authors collected 20 cases of CT diagnosed as pulmonary embolism patients, aged 20 to 80 years, mean 63 years, 10 males and 10 females, of which 13 cases of original lung disease, 7 cases of malignant lesions, 4 cases of vascular disease, except 3 Exceptions were dyspnea and chest pain symptoms. Prior to CT scans, 11 patients underwent lung perfusion perfusion scan, of which 6 were diagnosed as having a “high probability of pulmonary embolism” 4
