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.

Vermont tests elimination of payer pre-approvals for MRIs

The Green Mountain State is in the news for more than the entry of Independent Sen. Bernie Sanders into the 2016 race for president. A pilot healthcare-delivery project there experiments with removing a rule currently requiring patients to get pre-approval from their health plans for MRIs.

Got an EMR? Get an enterprise-wide ‘clinical imaging health record’

At a time when 85% of physicians are viewing diagnostic images via electronic medical records, the opportunity is ripe to realize true enterprise imaging. More of those docs should be saying goodbye to walled-off image silos and hello to a centralized, always-open image depot.

We’re all MRU experts now

The medical imaging community is buzzing over the GE MRI recall—by now, no other words are needed to name it—and the chatter will probably continue for a long time to come.

GE recalls thousands of MRIs

GE is recalling almost 13,000 MRI units, as the FDA has deemed them potentially deadly.

New York radiology practice replaces two MR systems with one; Significantly grows volumes

Sponsored by Hitachi Healthcare Americas

Serving the community of upstate New York’s Capital Region, Adirondack Radiology Associates (ARA) recently expanded patients’ access to state-of-the-art, high-field open bore MR imaging technology, replacing two systems, an older low-field open system and a closed 1.5T system, with the Hitachi Oasis high-field open MR at their Saratoga Imaging Center. Since the installation, ARA has experienced an increase in procedure volumes and patient satisfaction as well a reduction in costs.

Battling Burns in MRI

While MRI is often considered one of the safer imaging modalities due to its lack of ionizing radiation, other dangers remain for patients, with thermal burns being a chief concern.

Among the many requirements a hospital must meet to achieve and maintain the designation of Critical Access Hospital (CAH), the hospital must be fairly remote and furnish 24-hour emergency care services seven days a week, using either on-site or on-call staff.
