对MRI扫描在研究腭咽闭合功能中的价值的初步研究结果进行了讨论。MRI在无创方面比鼻内窥镜有潜在的优势，在避免辐射方面比视频透视有潜在的优势。然而，它需要昂贵的设备和患者合作，这限制了它在年轻患者中的使用。对10名正常志愿者和15名语音障碍患者进行了静息和持续发音时的腭咽口MRI检查。确定了最佳扫描平面。在正中矢状面、冠状面和水平面上，在硬腭水平和提升器轴线平面上获得图像。计算机辅助测量可以测量腭咽闭合、咽后壁前移、咽后壁上提、咽后壁伸展和咽外侧壁的内侧运动。MRI在腭咽闭合不全的研究和手术修复中具有潜在的应用价值。
The results of a pilot study into the value of MRI scanning in investigation of velopharyngeal function are discussed. MRI offers potential advantage over naso-endoscopy in being noninvasive and over video fluoroscopy in avoiding radiation. However, it requires costly equipment and patient cooperation, which limits its use in young patients. Ten normal volunteers and 15 patients with speech problems underwent MRI of the velopharyngeal port at rest and during sustained phonation of word /a/. Optimal planes for scanning were determined. Images were obtained in mid-sagittal, coronal and horizontal planes at the level of the hard palate and in the plane of the levator axis. Computer assisted measurements were possible of the velopharyngeal closure, forward movement of posterior pharyngeal wall, velar lift, velar extensibility and medial movement of the lateral pharyngeal wall. MRI has a potential role in investigation of velopharyngeal incompetence and planning its surgical repair.
