目的:对螺旋CT用于肺栓塞诊断中的价值进行研究,为临床诊断提供指导。方法:对2013年9月-2014年9月间我院呼吸内科就诊的疑似肺栓塞患者进行筛选,选取符合研究的84例为研究对象,分别采用普通CT和螺旋CT进行检查,并按检查结果进行诊断。就检出率,直接征象等数据进行组间比较。结果:普通CT组肺栓塞检出率为45.2%低于螺旋CT组88.1%的肺栓塞检出率,且具有显著差异性(P<0.05);在中心型充盈缺损、部分充盈缺损、完全阻塞、附壁充盈缺损等肺栓塞直接征象的组间比较中螺旋CT组均显著优于普通CT组(P<0.05)。结论:螺旋CT检测用于肺栓塞的检测中具有检出率高,直接征象明显等优势,适于临床推广使用。
Objective: To study the value of spiral CT in the diagnosis of pulmonary embolism and provide guidance for clinical diagnosis. Methods: From September 2013 to September 2014, we conducted a screening of suspected pulmonary embolism patients in our hospital for respiratory medicine. 84 patients who were eligible for the study were selected as subjects and examined by ordinary CT and spiral CT respectively. According to the test results Diagnose. On the detection rate, direct signs and other data for comparison between groups. Results: The detection rate of pulmonary embolism in common CT group was lower than that of spiral CT group (45.2%), which was significantly lower than that of spiral CT group (88.1%) (P <0.05). In central filling defect, partial filling defect and complete obstruction , And the direct signs of pulmonary embolism such as filling defect in the inferior wall of the spiral CT group were significantly better than the normal CT group (P <0.05). Conclusion: The detection of spiral CT in the detection of pulmonary embolism has the advantages of high detection rate and obvious direct signs, which is suitable for clinical application.
