MRI Safety information for:

MEDTRONIC, INC.

Bone-screw internal spinal fixation system, non-sterile

The LIBERTY™ Posterior Spinal System was not directly tested; the CD HORIZON™ Spinal System was selected to represent that system due to similarity of materials and a configuration at least as challenging to MRI imaging as the LIBERTY™ Posterior Spinal System. Bench top testing of the worst case system, the CD HORIZON™ Spinal System resulted in classifying the system MR-Conditional in 1.5 Tesla and 3.0 Tesla MRI systems.
