| 中文摘要: |
| T1加权三维磁化强度预备梯度回波序列(T1WI-3D-MP RAGE)属于快速容积扫描技术,具有较高的空间分辨率和时间分辨率,信噪比高,伪影小,对脑内结构(如白质、灰质和脑脊液)的对比度良好,能三维显示人脑内部精细解剖结构,有利于显示小病灶及其细节,对神经系统疾病的诊断具有重要价值,同时也是获取正常人脑的三维可视化图谱的重要方法,因此,对临床、科研和教学具有重要意义。 |
| 英文摘要: |
| Three-dimensional magnetization prepared rapid acquisition gradient echo sequences (T1WI-3D-MP RAGE) is a small-flip-angle, gradient-recalled-echo sequence with a 3D Fourier transform acquisition technique that has been implemented with 180° inversion recovery preparation pulse. This sequence considerably improved delineation of grey and white matter and small anatomical structures of brain due to its relatively temporal and spatial resolution, a relatively high signal-to-noise ratio (SNR), three-dimensional data acquired and post-processing capabilities. It has very important role not only in diagnosis of central nerves system but also a vital Methods to get the digitized human brain atlas. |
