目的：在磁共振成像基础上对冠状位正常成人海马结构进行测量，了解海马体积的正常值，为临床相关疾病的诊断提供参考数据。方法：对68例正常成人颅脑进行3D-fSPGR 序列扫描，利用软件对胼胝体嘴部后缘与胼胝体压部后缘间进行冠状位图像10等分，并逐层勾勒海马结构的面积，然后计算体积，数据通过 SPSS 17．0软件分析。结果：正常成人海马结构绝对体积左侧为（2319．63～2610．73）mm3、右侧为（2447．52～2749．50）mm3，相对体积左侧为（2319．87～2602．47）mm3、右侧为（2443．96～2755．89）mm3。海马结构平均体积与年龄不存在相关性（r＝0．084，P＝0．549），右侧海马结构绝对体积在青年组性别差异显著（t＝2．500，P＝0．029），海马结构绝对体积左、右两侧差异存在显著性（t＝2．571，P＝0．022），相对体积左、右两侧差异存在显著性（t＝2．600，P＝0．021），女性右侧海马结构绝对体积中年组与青年组之间差异有显著性（P＝0．038）。结论：正常成人海马结构体积的大小与年龄、性别无关，海马结构体积右侧大于左侧。
目的：在磁共振成像基礎上對冠狀位正常成人海馬結構進行測量，瞭解海馬體積的正常值，為臨床相關疾病的診斷提供參攷數據。方法：對68例正常成人顱腦進行3D-fSPGR 序列掃描，利用軟件對胼胝體嘴部後緣與胼胝體壓部後緣間進行冠狀位圖像10等分，併逐層勾勒海馬結構的麵積，然後計算體積，數據通過 SPSS 17．0軟件分析。結果：正常成人海馬結構絕對體積左側為（2319．63～2610．73）mm3、右側為（2447．52～2749．50）mm3，相對體積左側為（2319．87～2602．47）mm3、右側為（2443．96～2755．89）mm3。海馬結構平均體積與年齡不存在相關性（r＝0．084，P＝0．549），右側海馬結構絕對體積在青年組性彆差異顯著（t＝2．500，P＝0．029），海馬結構絕對體積左、右兩側差異存在顯著性（t＝2．571，P＝0．022），相對體積左、右兩側差異存在顯著性（t＝2．600，P＝0．021），女性右側海馬結構絕對體積中年組與青年組之間差異有顯著性（P＝0．038）。結論：正常成人海馬結構體積的大小與年齡、性彆無關，海馬結構體積右側大于左側。

Objective To investigate the volume of hippocampal formation in normal adult using coronal magnetic resonance imaging. Methods 3D-fSPGR sequence was used to depict the brain in 68 healthy adult. The volume of hippocampus was calculated by drawing the outline of 10 coronal hippocampal formation images acquired equally form posterior border of rostrum corpus callosum to anterior border of the splenium. Data were analysed using the SPSS 17.0 software. Results In the coronal plane images of normal adult brain, the absolute volume of left and right hippocampal formation were 2 319.63-2 610.73 mm3 and 2 447.52-2 749.50 mm3 respectively . The relative volume of left and right hippocampal formation were 2 319 . 87-2 602 . 47 mm 3 and 2 443.96-2 755.89 mm3. There were no correlation between hippocampal volume and age (r = 0.084, P = 0.549. Significant gender differences (t=2.500, P=0.029) were observed between absolute volume of right hippocampal formation in the youth group. There were significant differences in the absolute volume (t = -2.571, P = 0.022), relative volume (t = 2.600, P = 0.021) among the right and left hippocampal formation. Significant absolute volume differences (P = 0.038) were observed between the middle-aged group and the youth group among the hippocampal formation of women. Conclusion No significant differences were observed in age, gender among the hippocampal volume of normal adult, and there was a significant difference between the left and right hippocampal formation volume.
