【摘要】 目的 探讨分析多层螺旋CT(MSCT)三维重建图像融合技术在气管及主支气管憩室诊断中的价值。方法 回顾性选取2021年4月至2024年3月在本院就诊疑似气管及主支气管憩室患者97例,均于术前完善MSCT检查,并采用三维重建图像融合技术[多平面重组(MPR)、容积重现(VR)、最小密度投影(minMIP)]进行后处理,以手术病理结果 作为金标准,分析MSCT三维重建图像融合技术对气管及主支气管憩室的诊断效能,记录气管及主支气管憩室影像学特征;并比较常规横轴位与MSCT三维重建图像融合技术对憩室与气管支气管之间通道的检出率。结果 手术病理诊断结果 显示,97例疑似患者中有84例为气管及主支气管憩室,13例为非气管及主支气管憩室。术前MSCT确诊气管及主支气管憩室82例,准确度为93.81%,敏感度为97.62%,特异度为69.23%,阴性预测值为81.82%,阳性预测值为95.35%,Kappa值为0.715。82例气管及主支气管憩室患者憩室大小不一,直径范围为12～48mm,平均直径为(30.05±2.45)mm,多位于气管右后侧,MSCT特征以单发憩室、单开口型、憩室内无分隔、与气管支气管相通、憩室壁菲薄、憩室内壁光滑为主。常规横轴位与MSCT三维重建图像融合技术对憩室与气管支气管之间通道的检出率对比有差异(P<0.05)。结论 MSCT三维重建图像融合技术对气管及主支气管憩室有较高的诊断价值,可为临床诊断提供可靠的影像学资料。更多还原

【Abstract】 Objective To explore the diagnostic value of multi-slice spiral CT(MSCT) three-dimensional reconstruction image fusion technique in tracheobronchial dive rticulum.Methods A total of 97 patients with suspected tracheobronchial diverticulum in the hospital were retrospectively enrolled between April 2021 and March 2024.All underwent MSCT examination before surgery and aftertreatment by three-dimensional reconstruction image fusion technique [multiplanar recombination(MPR),volume reconstruction(VR),minimum density projection(minMIP)].Taking pathological results as the golden standard,diagnostic efficiency of MSCT three-dimensional reconstruction image fusion technique for tracheobronchial diverticulum was analyzed.The imaging characteristics of tracheobronchial diverticulum were recorded.The detection rate of channel(between diverticulum and tracheal bronchus) by routine tra nsverse view and MSCT three-dimensional reconstruction image fusion technique was compared.Results The results of pathological diagnosis showed that in the 97patients with suspected tracheobronchial diverticulum,there were 84 positive cases and 13 negative cases.MSCT showed that there were 82 cases with tracheobronchial diverticulum,and its diagnostic accuracy,sensitivity,specificity,negative predictive value,positive predictive value and Kappa value were 93.81%,97.62%,69.23%,81.82%,95.35%,and 0.715,respectively.The size of diverticulum in the 82 patients was different,with diameter range and average diameter of 12～48mm and(30.05±2.45) mm,most of diverticulum was located on the right posterior side of trachea.The main MSCT characteristics included single diverticulum,single-opening type,no separation in dive rticulum,communication with trachea and bronchus,thin diverticulum wall and smooth diverticulum wall.There were significant differences in detection rate of channel(between diverticulum and tracheal bronchus) by routine transverse view and MSCT three-dimensional reconstruction image fusion technique(P<0.05).Conclusion MSCT three-dimensional reconstruction image fusion technique has high diagnostic value for tracheobronchial diverticulum,which can provide reliable imaging data for clinical diagnosis.更多还原
