The Value of MRI-Guided Biopsy

With its lack of ionizing radiation, MRI is not only a safe tool for biopsy guidance, but one of the most sensitive imaging modalities available to delineate abnormalities in soft tissue and bone marrow.

The technology’s multi-planar capability is helpful in performing biopsies in non-axial planes without the need for image reformatting.

Other imaging modalities are capable of evaluating structures similar to the way that MRI does, but MRI is also able to provide data useful in assessing functions such as temperature or velocity that are potentially crucial in monitoring an intervention.

Since the start of our Interventional MRI Program in April 2008 we have performed several hundred biopsies and other interventions.

We are continuously adding to our tools and techniques, such as tumor ablation and radioembolization, enabling us to provide an increasingly wide array of interventions. As part of our commitment to evolving and improving what we can offer patients, for example, we are collaborating with General Electric to design a new set of dedicated interventional surface coils that can facilitate MRI-guided interventions and improve visualization.
