Skin-port tissue expander

Diagnostic testing with Magnetic Resonance Imaging (MRI) is contraindicated in patients with magnetic injection/drain port expanders in place. The MRI equipment could cause movement of the magnetic injection/drain port and/ or expander, and result in not only patient discomfort, but also expander displacement, requiring revision surgery. In addition, the magnet could interfere with MRI detection capabilities.
