深静脉血栓是一种世界范围的严重临床疾患,必须准确检测,该文目的是评价在肺动脉CT成像基础上附加间接CT静脉成像检查怀疑肺栓塞的患者是否有深静脉血栓的临床优势。作者前瞻性选择1998年5月～1999年3月期间541例怀疑肺栓塞病人行肺动脉CT成像及CT静脉成像。男性233例,女性308例。年龄18～98岁,平均65岁。通过臂静脉以3ml/s注射对比剂140ml。延迟28s后进行螺旋CT扫描。扫描从下肺静脉直至主动脉弓,层厚
Deep venous thrombosis is a worldwide serious clinical condition and must be accurately examined. This paper aims to evaluate the clinical advantages of additional CT indirect venography in detecting pulmonary embolism in patients suspected of having pulmonary embolism based on pulmonary computed tomography. The authors prospectively selected 541 cases of suspected pulmonary embolism during May 1998 ~ March 1999 pulmonary artery CT imaging and CT venography. 233 males and 308 females. Age 18 ~ 98 years old, average 65 years old. The contrast agent 140 ml was injected through the arm vein at 3 ml / s. Spiral CT scan was performed after 28s delay. Scan from the lower pulmonary vein until the aortic arch, layer thickness
