Objective To evaluate MRI diagnostic value in central diabetes insipidus, and discuss its pathogenesis.
目的评价MRI对中枢性尿崩症的诊断价值，探讨中枢性尿崩症的发病机理。
Central diabetes insipidus is usually idiopathic, but can also be caused by head trauma or tumors of the brain.

AIM: to observe the effects of supraoptic ADH neurons and central diabetes insipidus (CDI) in Wistar rats at different times after hypophysectomy.
目的：观察大鼠垂体切除后不同时段对下丘脑视上核adh神经元的影响及尿崩情况。
Conclusion Minirin is equal to pituitrin in water deprivation test for the diagnosis of central diabetes insipidus. Minirin replacing pituitrin in water deprivation is feasible.
结论垂体后叶素和弥凝两种药物在诊断中枢性尿崩症方面结果一致，用禁水-弥凝试验替代禁水-加压素试验是可行的，而且临床操作更加方便。
