Abstract
Magnetic resonance imaging of 30 normal volonteers' posterior fossae was performed on a CGR Magniscan machine with a magnetic field strength of 0.5 Tesla. We chose the inversion recovery signal with a Tr of 2,000 ms, a TE of 21 ms and an inverse time of 500 ms. This sequence gives a better definition of the grey matter, the white matter and the CSF. To study the brain stem we suggest 8 horizontal and 3 sagittal sections.
摘要
对30名正常志愿者的后颅窝进行了磁共振成像，使用的是磁场强度为0.5特斯拉的CGR Magniscan机器。我们选择了反转恢复信号，其重复时间（Tr）为2000毫秒，回波时间（TE）为21毫秒，反转时间为500毫秒。该序列能更好地显示灰质、白质和脑脊液。为研究脑干，我们建议采用8个水平切面和3个矢状切面。
