摘要
目的分析多层螺旋CT(MSCT)及后处理技术在急性阑尾炎诊断中的价值核心思路。方法选取北京市朝阳区双桥医院2018年7月-2020年7月收治的112例疑似急性阑尾炎患者作为观察对象,实施多层螺旋CT平扫、增强扫描和三维重建。疾病诊断时,对照组将单纯轴位像作为主要依据;研究组将轴位结合多平面重建作为主要依据。观察并对比两组患者的临床诊断结果。结果经MSCT扫描轴位像CT图诊断,对照组放射科医师发现94例阑尾炎患者,7例误诊,11例漏诊。经MSCT扫描轴位像CT图与多平面重建(MPR)图结合诊断,研究组放射科医师发现104例阑尾炎患者,3例误诊,5例漏诊。在5分制可信度积分中,研究组确诊的阑尾炎患者共有96例,对照组确诊的阑尾炎患者共有66例。研究组可信度明显高于对照组,组间比较差异有统计学意义(P<0.05)。研究组的诊断敏感性、诊断特异性、诊断准确性均明显高于对照组,组间比较差异有统计学意义(P<0.05)。结论在急性阑尾炎诊断时采用多层螺旋CT及后处理技术,能显著降低漏诊率和误诊率,增强鉴别诊断能力的同时,还能提高诊断信心。
Objective To analyze value of multi-slice spiral CT(MSCT)and post-processing technology in diagnosis of acute appendicitis.Methods The paper chose 112 patients with suspected acute appendicitis from July 2018 to July 2020 in Chaoyang District Shuangqiao Hospital as observation objects,and carried out multi-slice spiral CT plain scan,enhanced scan and three-dimensional reconstruction.During disease diagnosis,control group was treated with simple axial image as main basis;research group with axial position combined with multi-plane reconstruction as main basis.Clinical diagnosis results between two groups were observed and compared.Results MSCT axial image CT diagnosis showed,radiologists in control group found 94 cases of appendicitis,7 cases were misdiagnosed and 11 cases were missed.Combined diagnosis of MSCT axial image CT and multiplanar reconstruction(MPR)showed,radiologists in study group found 104 cases of appendicitis,3 cases were misdiagnosed and 5 cases were missed.5-point reliability scores showed,96 cases with appendicitis were confirmed in study group and 66 cases with appendicitis in control group.Credibility of study group was significantly higher than control group,difference between groups was statistically significant(P<0.05);diagnostic sensitivity,specificity and accuracy of study group was 98.00%,75.00%and 92.86%respectively;diagnostic sensitivity,specificity and accuracy of control group was 86.00%,41.67%and 83.93%respectively.Diagnostic sensitivity and accuracy of study group was significantly higher than control group,difference between two groups was statistically significant(P<0.05).Conclusion Multislice spiral CT and post-processing technology can reduce missed diagnosis and misdiagnosis rate,enhance ability of differential diagnosis,and improve diagnostic confidence significantly in diagnosis of acute appendicitis.
