The microtransponder (Qid®) is MRI-safe. The device is “MRI conditional”, meaning that it has been demonstrated to pose no known hazards in a specified MRI environment with specified conditions of use.
Qid® may create an imaging void during MRI (known as an artifact effect) that can block visualization of a small area of minor breast tissue near it. In special cases, alternative imaging techniques such as ultrasound, tomosynthesis, digital compression mammography, subtraction contrast mammography, and/or scintimammography can be used to better visualize the region obstructed by Qid®.
