Neuroimaging and functional examination in hydrocephalus: a comment.

All the papers were of a high scientific standard, giving us clearly defined information that will be applicable in the diagnosis and further management of infantile hydrocephalus. Particularly interesting subjects were the comparison of CT and MRI in the evaluation of hydrocephalus and cine MRI, which allows evaluation of the CSF dynamic flows. CBF measurements with xenon CT/CBF imaging or transcranial Doppler examinations of CBF velocity are used much more for evaluation of the shunt indications for shunting and also for definition of the outcome of shunting procedures. Although measurements of physiological CSF parameters are important, studies on the pathophysiology of hydrocephalus should be focused on the changes in CBF in hydrocephalus patients. The key points and conclusions presented by each author are discussed and the prospects mentioned for the future in neuroimaging and functional examination in hydrocephalus.
