目的：报告使用三维(3D)磁共振成像(MRI)检查腭咽闭合结构的可行性。利用收集的3D MRI数据，研究性别对正中矢状面腭咽闭合结构和提腭帆(提上提肌)肌肉形态的影响。参与者在仰卧位休息时，进行了全头3D MRI扫描。比较不同性别腭咽闭合结构和提肌形态的基本解剖参数。结果：详细介绍了3D MRI的成像方案和数据分析方法。根据这些数据，只有提肌的长度显示出显著的性别差异：男性参与者的提肌长度显著长于女性参与者。结论：本研究成功地展示了3D MRI在主要腭咽闭合结构中的应用，并为健康成年人存在的解剖变异提供了额外的数据。
Purpose: To report the feasibility of using a 3-dimensional (3D) magnetic resonance imaging (MRI) protocol for examining velopharyngeal structures. Using collected 3D MRI data, the authors investigated the effect of sex on the midsagittal velopharyngeal structures and the levator veli palatini (levator) muscle configurations.Method: Ten Caucasian healthy adults (5 women and 5 men) participated. A whole-head 3D MRI scan was obtained while participants were at rest in the supine position. Basic anatomic parameters of the velopharynx including midsagittal velopharyngeal structures and levator muscle configurations were compared between sexes.Results: Detailed information on the 3D MRI protocol and data analysis method was introduced in the study. On the basis of the data, only the length of the levator muscle showed a statistically significant sex difference: Male participants had significantly longer levator muscles than those of female participants.Conclusions: The present study successfully demonstrated the use of 3D MRI in quantifying major velopharyngeal structures and provided additional data on the anatomic variations that exist in healthy adult individuals.
