摘　　要：目的利用3.0T磁共振探寻显示伏隔核的最佳方式。方法对32名健康志愿者进行头部常规及容积扫描。将容积扫描图像进行不同角度重建,分为12组。对各组重建伏隔核图像进行打分评价并分析。结果男女性别间分值差异无统计学意义,与前后连合连线垂直的90°组与其它角度组间的差异均有统计学意义(P<0.05)。结论3.0T磁共振可以较好显示伏隔核,扫描伏隔核最佳方案应为垂直于前后连合连线的冠状位扫描。Objective To search for the best way in displaying the nucleus accumbens by means of 3.0T MRI scanner. Methods 32 healthy volunteers underwent the routine and volume MR imaging examination of brain, and then the volume images were reconstructed and classified into 12 groups based on the different reconstructing angles. The reconstructed images of each group were scored according to the degrees of whether the nucleus accumbens was completely displayed or not. Results Between male and female, the display of the nucleus accumbens had no statistical significance, but it did has significant difference between the group with the reconstructing angle 90° and other groups（P〈0.05 ）. Conclusion 3.0T MRI can display the nucleus accumbens effectively and excellently. The best method to show the nucleus accumbens is the coronal scan, its plane should be vertical to the line between anterior - posterior commisure.
