Summary
The diagnostic value of cerebrospinal fluid (CSF) flow measurements in patients with normal pressure hydrocephalus (NPH) was studied using two MRI [double phase encoded (DOPE) and fast Fourier flow (FFF)] techniques. Of 40 patients with the clinical symptoms of NPH, 19 were considered to require a ventricular shunt. Fourteen of these showed abnormal DOPE findings with a reflux pattern at the level of the foramina of Monro with velocities between 0.8 mm and 4 cm/s and increased velocities within the third and fourth ventricle. The FFF results with increased aqueductal flow velocities and hence pulsatility found in all patients examined did not differ from the findings in atrophic hydrocephalus (n = 2). The flow studies seem to improve the prediction of the therapeutic response and should be combined with the diagnostic removal of CSF and epidural or intraventricular pressure measurements.
