目的 探讨螺旋CT扫描对肺动脉血栓栓塞的诊断价值 ,重点分析平扫的影像学特点。方法 对 16例CT平扫误诊病例进行回顾性分析。结果 16例患者CT平扫均有阳性发现 ,敏感性为 10 0 %。其中误诊肺炎合并胸腔积液 11例 ;胸腔积液 3例 ;机化性肺炎 1例 ;周围型肺癌 1例。结论 CT平扫可提供肺栓塞存在与否的有力证据 ,简便、安全、敏感可靠 ,在有条件的地方 ,应将其作为替代平片的首选检诊方法。
Objective To investigate the diagnostic value of spiral CT in the diagnosis of pulmonary thromboembolism and focus on the imaging characteristics of plain scanning. Methods Retrospective analysis of 16 cases of CT misdiagnosis. Results 16 cases of CT scan were positive, the sensitivity was 10%. Including misdiagnosis of pneumonia with pleural effusion in 11 cases; pleural effusion in 3 cases; 1 case of avascular pneumonia; 1 case of peripheral lung cancer. Conclusion CT scan can provide strong evidence of the existence of pulmonary embolism, simple, safe, sensitive and reliable, where conditions permit, it should be used as the preferred method of screening for plain film.
