影像引导下经皮穿刺肺活检已成为一种常规的诊断技术,可借助透视及断面影像技术完成,其中CT应用最为广泛。作者比较了螺旋扫描与连续层面扫描在操作时间、病理结果、合并症的发生率及病人照射量等方面的差异。 作者研究了48例病人的50个肺内病变,男性32例,女性16例,年龄29～79岁。CT扫描采用具有螺旋扫描功能的第四代CT机。由2人操作,一位是具有穿刺经验的高年放射医师,一位是正在接受培 Image-guided percutaneous lung biopsy has become a routine diagnostic technique that can be performed with fluoroscopic and cross-sectional imaging techniques, of which CT is the most widely used. The authors compared the differences in the time of operation, the pathological findings, the incidence of comorbidities, and the amount of patient exposure between helical and continuous scan. The authors studied 50 lung lesions in 48 patients, 32 males and 16 females, aged 29 to 79 years. The CT scan uses a fourth generation CT scanner with helical scanning. Operated by 2 people, one is a senior radiologist who has a puncture experience and one is undergoing training
