Safety of the Adjustable Pressure Ventricular Valve in Magnetic-resonance-imaging - Problems and Solutions

Primary tabs

Fransen, P. Dooms, Grégoire [UCL] Thauvoy, Christian [UCL]

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.
