Safety of the adjustable pressure ventricular valve in magnetic resonance imaging: problems and solutions.

P Fransen1, G Dooms, C Thauvoy.   

Abstract

We performed magnetic resonance imaging in 30 patients with hydrocephalus with Sophy adjustable pressure valves (PAVS). A pressure check following the MRI study showed a significant proportion with pressure valve changes, which could easily be readjusted by percutaneous manipulation. The value of the PAVS and its safety during MRI examinations are discussed.
