MR imaging is the premier imaging modality for diagnosing the various forms and causes of hydrocephalus. Although CT is satisfactory for imaging in the axial plane, MR imaging is capable of imaging in any plane to better demonstrate any cause of observation. MR imaging also is more sensitive than CT to interstitial edema (transependymal flow of cerebrospinal fluid [CSF]) and to the hyperdynamic CSF flow seen with shunt-responsive normal-pressure hydrocephalus (NPH). MR imaging also is sensitive to the presence of deep white matter ischemia that may contribute to the cause of the idiopathic form of NPH.
磁共振成像（MR成像）是诊断脑积水各种形式及病因的首要成像方式。虽然CT在轴位成像方面令人满意，但MR成像能够在任何平面进行成像，以便更好地显示任何观察到的病因。MR成像对间质性水肿（脑脊液[CSF]经室管膜流动）和分流反应性正常压力脑积水（NPH）中所见的脑脊液高动力流动也比CT更敏感。MR成像对深部白质缺血的存在也很敏感，而深部白质缺血可能是特发性NPH病因的一个因素。
