Chiari malformations are a spectrum of anomalies associated with a reduction of posterior cranial fossa volumes and CSF while conserving overall brain volume. Chiari I malformations refer to a greater than 5 mm herniation of the cerebellar tonsils down through the foramen magnum.

chiari畸形是由于后颅窝容积及脑脊液减小而与正常的脑容积不匹配造成的一系列的异常病变的统称。chiariI型畸形是指小脑扁桃体下疝超过枕骨大孔5mm以上。

Methods:The depth of the anterior and posterior rims of foramen magnum and the angle between medulla oblongata and upper spinal cord on midsagittal SE or FSE T1WI were measured in 320normal Chinese individuals and in 36patients with basilar impression.

随机选取320例没有颅颈交界区相关的临床症状及体症，MRI扫描无明显颅骨破坏性病变和颅颈交界区畸形的正常国人和36例颅底凹陷症患者的颅脑MRI图像，于正中矢状面SE或FSE T_1WI图像上测量枕大孔前、后缘中点深度和延髓-上颈髓轴线夹角数值。正常人按性别、年龄分16组，每组20例。

Purpose:To determine the normal ranges of the depth of the anterior and posterior rims of foramen occipital magnum and the angle between medulla oblongata and the upper spinal cord on midsagittal MRI in normal Chinese idividuals and patients with basilar impression,to study their clinical significance and to provide normal reference in diagnosing basilar invagination by MRI.

目的：利用颅脑正中矢状面MRI自旋回波或快速自旋回波T_1WI图像测量颅颈交界区正常的中国人和颅底凹陷症患者枕大孔前、后缘中点深度和延髓-上颈髓轴线夹角数值，评价其正常值范围，探讨其发育规律及临床意义，为MRI诊断颅底凹陷症提供直接的参考标准。
