MRI, or Magnetic Resonance Imaging, is a technique for displaying internal organs and tissue. Unlike x-rays, it does not use x-ray beams but instead works on magnetic fields and radio waves. During the procedure, the patient lies on a so-called "bore" inside the machine. It is important to remain absolutely still and breathe regularly so the image is not distorted.
The benefit of this technique is that it provides very exact and differentiated views of all body tissue, particularly boneless parts, such as soft tissue, organs, joint cartilage, meniscus and the brain. Even minimal changes in the body, such as small inflammation sites can be detected using this method. This is why magnetic resonance imaging is used in the case of an inconclusive breast cancer diagnosis, to gather additional information or confirm the presence of the tiniest, non-palpable lumps that are invisible using other methods. Magnetic resonance imaging is also the most appropriate way of examining patients with breast implants.
