The effect on medical metal implants by magnetic fields of magnetic resonance imaging.

M Mesgarzadeh, G Revesz, A Bonakdarpour, R R Betz.   

Abstract

Forces and torques, due to a 0.3 Tesla magnetic field were evaluated on ten hip prostheses and ten hemostat clips. Measurements were performed with an instrument utilizing the movement of a laser beam caused by the deflection of a cantilever. The results indicate effects, if any, to be smaller than the instrument's sensitivity which, at its highest, was 7 mg of force and 125 mg.cm of torque.
