Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is the gold standard imaging modality for soft tissues. It produces detail cross-sectional images of soft tissue and bone anatomy, including muscles, tendons, ligaments, brain and organs, without the use of ionizing radiation. In addition to orthopedic imaging, MRI is also used for heart, brain and breast. MRI uses gadolinium contrast in many exams to highlight tissues and blood vessels, which enhances images and offers better diagnostic quality. It can also be used in conjunction with PET scans. How does MRI work? MR creates images by using powerful magnets to polarize hydrogen atoms in water (the body is made of of more than 80% water) so they face in one direction. A radiofrequency pulse is then used to ping these atoms, causing them to wobble, or resonate. The MRI coils detect this and computers can assemble images from the signals. Basic MRI scans will focus on the resonance of fat and water in two different sequences, which highlight and contrast different features in the anatomy.

Time in nature changes kids' brains on a structural level, imaging data show

Cardiologists make history, perform world’s first ventricular ablation guided by real-time MRI

“MRI images provide a better view of the anatomy of the heart and the instruments used for treatment, but also of the changes made to the treated cardiac tissue,” one cardiologist explained. “Unlike X-ray images, the entire area surrounding the heart can be seen, including the blood vessels and valves."

Reducing MRI scan times could add thousands of exam slots, generating up to $22M in new revenue per practice

That’s according to a new retrospective study led by the University of California, San Francisco, and Siemens Healthineers, published Tuesday in Radiology.
