MRA finds value in hydrocephalus interventions

November 1, 2008 Diagnostic Imaging. Vol. 30 No. 11 MRA finds value in hydrocephalus interventions Imaging research from the University Medical Center Utrecht, the Netherlands, suggests that measuring with MRI the intracranial pressure of infants with progressive hydrocephalus helps physicians to determine the right time for surgical intervention. According to a study published in the Journal of Neurosurgery: Pediatrics (2008;2[3]:163-170), the clinical signs of raised intracranial pressure associated with hydrocephalus can be unreliable and even misleading, mak-ing it difficult to tell if a shunt system is needed to divert excess cerebro-spinal fluid. Adding to the uncertainty, after sutures close in infants, actual intracranial pressure does not always correlate with ventricular size or clinical signs or symptoms.
