应用3．0TMRI技术对于神经精神疾病患者海马各部体积的测量

The application of 3.0 TMRI in voluminal changes of hippocampus locations in nervous and mental diseases

目的：探讨各类神经精神疾病所导致海马各部位的体积改变。方法：应用3．0T磁共振常规序列计算各类神经精神疾病海马各部体积。结果：颞叶癫癎组病人双侧海马头及海马总体积均小于正常组；同组癫癎病人双侧海马各部及总体积相差不大。抑郁症病人组内，左侧海马尾部及左侧海马总体积均小于右侧，与正常组比较，双侧海马尾部、左侧海马体部及双侧海马总体积均小于正常组。精神病组双侧海马各部及海马总体积相差不大，双侧海马头部、体部及海马总体积均小于正常组。结论：应用3．0TMRI技术能够清晰界定海马各部并能测量体积。

Objective：To investigate voluminal changes in various hippocampus volume caused by nervous and mental diseases. Methods：3.0 TMRI routine sequence method was used to calculate the volume of various parts of hippocampal volume in nervous and mental diseases. Results：The bilateral hippocampal head and total hippocampal volume of the temporal lobe epilepsy group were smaller than that of the normal group. There was almost no difference in bilateral hippocampal volume and total volume of patients with epilepsy in the same group. The tail and left hippocampal volume on the left side was smaller than on the right side in patients with depression,and their bilateral hippocampal tail, the hippocampal volume on the left side and bilateral hippocampal volume were all smaller than those in the normal group. Bilateral hippocampal volume of different parts and total hippocampal volume in patients with mental disorder were similar and their bilateral hippocampal body, head and total volume were smaller than in the normal group. Conclusion：3.0 T MRI can clearly measure the volume of various parts of the hippocampus and the volume.
