    Study Notes

    Guidelines for Breast Tissue Expanders and Preventing Excessive Heating and Burns in MRI Procedures

    Breast tissue expanders and mammary implants are used for various procedures, including breast reconstruction and cosmetic augmentation.

    Different breast tissue expanders have different injection ports, with some containing magnetic ports that may cause discomfort or artifacts during MRI procedures.

    A recent investigation found that the Integra Breast Tissue Expander with a remote port can safely undergo MRI at 3-Tesla or less with the conditions used for the evaluation.

    MR imaging is generally safe, but certain conductive materials and objects can cause excessive heating and burns during MRI procedures.

    Over a ten-year period, 419 thermal injuries associated with MRI were reported in the US, some caused by skin-to-skin contact points or direct contact with transmit body radiofrequency coils.

    To prevent excessive heating and burns, patients should change into a gown or non-metallic attire, and insulation material should be used to prevent skin-to-skin contact points.

    Insulating material should also be placed between the patient's skin and the transmit RF coil used for the MR procedure.

    Electrically conductive devices, equipment, and accessories should be thoroughly tested and determined to be safe or otherwise acceptable for MR procedures.

    Conductive materials should be positioned to prevent the formation of conductive loops and cross points, and should not be placed across external metallic prostheses.

    Patients should not wear clothing items with metal-based fibers during MR procedures, and should be closely monitored for any sensations of heating or unusual sensations.

    Adopting and regularly practicing these guidelines will ensure patient safety, especially as more conductive materials and electronically-activated devices are used in association with MR procedures.
