Diversion of CSF in hydrocephalus by shunting is often necessary. However, shunting is associated with high failure rate (40% in the first year). The decision to place or revised a shunt is based on symptoms and radiographic imaging of ventricular size. Because symptoms often may not be specific and ventricular size may not correlate with abnormal ICP there is a need for a diagnostic test to assist in the treatment decision. We reports early experience from the first application of an MRI-based measurement of ICP in hydrocephalus. Patients with symptoms suggestive of elevated ICP or shunt malfunction underwent MR-ICP and were retrospectively evaluated with respect to the short-term outcome to assess its predictive values.
