To assess the effects of age and gender on the interuncal distance measured from MR images.
High-field strength MR images (axial) of 75 volunteers, 21-82 years old and free of neurologic disorders, were used to measure the interuncal distance.
The interuncal distance increased with age (r = 0.66, P < .0001). The mean (SD) interuncal distance for all subjects was 21.4 (4) mm with a range of 12 to 29 mm.
The interuncal distance in healthy subjects is unlikely to exceed 30 mm. Our data may be of clinical significance in view of a previous report stating that the interuncal distance may be enlarged in pathologic hippocampal degeneration, such as in patients with Alzheimer disease.
评估年龄和性别对从磁共振成像（MR）测量的大脑脚间距离的影响。
对75名年龄在21至82岁且无神经系统疾病的志愿者的高场强MR图像（轴位）进行大脑脚间距离测量。
大脑脚间距离随年龄增加（r = 0.66，P <.0001）。所有受试者的平均（标准差）大脑脚间距离为21.4（4）mm，范围为12至29 mm。
健康受试者的大脑脚间距离不太可能超过30 mm。鉴于之前有报告称在病理性海马退变（如阿尔茨海默病患者）中大脑脚间距离可能增大，我们的数据可能具有临床意义。
