| 目的：研究正常人垂体后叶短T1高信号与垂体后叶内神经分泌颗粒含量的相关性。方法：用5例头部标本行垂体MR成像及垂体标本电镜观察, 测量垂体后叶信号强度比与电镜下垂体后叶单位面积内神经分泌颗粒、脂滴的量, 并进行相关与回归分析。结果：5例垂体后叶均呈短T1高信号；电镜下, 垂体后叶含丰富的神经分泌颗粒, 而脂滴少。 |

| Purpose:To study the correlation between posterior pituitary high signal and neurosecretory granules in the posterior lobe of pituitary gland.Methods:MR images of pituitary gland were performed on five cranial cadavers.Then observed by electron microscopic.The signal intensity ratio of posterior pituitary gland and the amount of neurosecretory gland were measured;analysed with correlation and regression.Results:Posterior pituitary high signal were seen in five cases;There were abundnt neurosecretory granules in the posterior lobe of pituitary gland.but a few lipid droplets.Conclusion:Posterior pituitary high signal seen on T1 weighted MR images is attributed to neurosecretory granules,and having linear positive correlation. |
