This policy does not cover patients with internal fixation devices i.e. orthopaedic implants fixed to the bone and entirely held within the body.
This policy considers 1.5T and 3T MRI scanning of patients with external fixation devices i.e. devices which are fixed to bone but also extend beyond the surface of the patient’s skin.
NHSL Policy: The NHSL Policy will be as per GGC Policy, which states:
“Until recently external fixation devices were considered to be a contraindication for MRI. However, there have recently been products brought onto the market which are MR Conditional. Therefore, if a patient presents for MRI with an external fixation device. The make and model of the fixation device must be established. The MRI safety status must then be confirmed e.g. from manufacturers instructions from use (IFU). If the External fixation device is MR Conditional, ensure you can satisfy the MR conditions for safe scanning before you proceed.
Guidance for all health professionals involved with patients with Hoffmann 3 devices having MRI scans can be found here. Extra care must be applied when determining the make and model of the external fixation device and the specific MR conditions. For example, the Standard Hoffmann 2 external fixation device is MR Unsafe, whereas, the Hoffmann 2 MRI and Hoffmann 3 MRI are MR Conditional.
