摘要:

目的 探讨多层螺旋CT的各向同性扫描对于翼腭窝结构及其相关通道的完整显示,多平面重组(MPR)步骤,及其临床应用价值。 方法 运用Siemens 16 CT扫描仪行鼻窦螺旋CT检查,选取 100名无翼腭窝及其通道病变的成人,由工作站进行容积显示(VR)、最大密度投影(MIP)及多平面重组 (MPR),观察翼腭窝结构及其通道的形态、走行。 结果 圆孔、翼管、蝶腭孔、翼腭管、腭鞘管、犁鞘管在其最佳辨认方位上显示率分别为99%、98%、99%、96%、96%、85%。 结论 多层螺旋CT能多方位而且直观地显示翼腭窝骨性结构及其通道,能为早期发现相关病变及为制订临床治疗方案提供影像学依据。

Abstract:

Objective To explore Multi-slice spiral CT Isotropic Scanning features of the pterygopalatine fossa (PPF)and its communications,the method of reconstruction by multiplanar reformation (MPR), study the  Clinical value.  Method Multi-slice spira CT images of Siemens 16 were performed in 100 adult patients for paranasal sinusitis without abnormality in PPF communications.All original images were transferred to workstation for image processing.According to the shape and appearance of the PPF communications,the best depictive multiplanar reformation(MPR)、maximum intensity projection(MIP)、volume rendering(VR) images were acquired for study.To observe the structure of the pterygopalatine fossa and the channel.  Results The visualization rates of the foramen rotundum,the  pterygoid canal ,the sphenopalatine foramen,the pterygopalatine canal,the palatovaginal canal and the vomerovaginal canal were 99%、98%、99%、96%、96% and 85% respectively.  Conclusion Images of Multi-slice spiral CT could accurately demonstrate the shape of the PPF communications and their adjacent structures,and provide scientific and objective foundation for early detection and the formulation of clinical treatment programs.
