摘　　要：目的:探讨如何改进螺旋CT仿真内窥镜检查技术,以提高腺样体肥大患者三维成像质量。方法:利用螺旋CT仿真内窥镜技术对32例腺样体肥大患者进行检查,合理调整扫描参数、控制成像方向,形成三维鼻咽前视位及后视位仿真内镜影像,将螺旋CT检查情况与术中或鼻内窥镜结果进行统计比较。结果:本组腺样体肥大患者全部完成CTVE检查,CTVE前视位与NE检查后鼻孔阻塞程度结果进行统计学一致性分析,配对卡方χ2=4.000,P=0.261(>0.05),Kappa检验值为0.806(>0.75)。提示2组数据一致性较好,诊断方法无显著性差异。结论:利用螺旋CT仿真内窥镜技术对腺样体肥大患者检查时合理调整扫描参数、控制成像方向,可取得对临床有价值的三维重建影像。Objective To investigate how to make the inspecting technology better to further improve the adenoids hypertrophy patients＇ 3D image quality.Methods CTVE technology was used to conduct an examination toward 32 cases of adenoid hypertrophy.The scanning parameters were adjusted properly,then after controlling the imaging direction,the 3D images of the nasopharynx were formed in the virtual NE＇s front and rear position.The result of CT inspection were calculated and compared with that of CTVE technology or NE.Results All the adenoid hypertrophy patients were inspected by CTVE in this group.The statistical consistent analysis was performed about the posterior naris obstruction＇s extent inspected by CTVE at the front position and NE respectively,withχ2 value of 4.000,P value of 0.261（0.05） by Mateχ2 Test,and the value of 0.806（0.75） by Consistency Test kappa.Two groups of the statistics had a good consistency,and the diagnosis with various methods had no significant difference.Conclusion When inspecting the adenoidal hypertrophy patients by CTVE,the scanning parameters have to be adjusted properly,and the image direction has to be controlled,then the 3D reconstruction image can be achieved,which plays an important role in clinic.
