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
New findings published in Biological Psychiatry provide insight into the connection between time spent outside and improvements in neurodevelopment.
Calcified carotid plaques more likely to rupture than previously believed, MRI findings suggest
Ruptured plaques can lead to the formation of blood clots that significantly increase the risk of stroke.
FDA approves expanded use of 'powerful' lung imaging tool
The approval will make around 1 million more patients eligible to receive the specialized contrast, which enhances the evaluation of lung ventilation.
Prenuvo reveals early findings from elective whole-body MRI clinical trial
The Redwood City, California-based radiology group has enrolled 1,011 “mostly asymptomatic” individuals who underwent whole-body MRIs as part of its “real world” Polaris study.
Study challenges use of MRI in spontaneous deep intracerebral hemorrhage
Spontaneous ICH carries a heightened risk of mortality, making locating its origin in a timely manner critical to outcomes.

Hospital for Special Surgery pediatric MRI

MSK team achieves 0% sedation rate for pediatric MRI

Almost 2,000 children underwent musculoskeletal MRI over an eight-year stretch at the Hospital for Special Surgery, and not a single one of them needed sedation to get through the exam.

John Simon, MD, CEO of SimonMed Imaging, said imaging had greatly advanced for noninvasive detection of disease and it may be time for imaging to play a greater role in annual physicals, and especially in executive physical exams.

Should more imaging be included in physicals?

John Simon, MD, CEO of SimonMed Imaging, says imaging has considerably advanced for noninvasive detection of disease and it may be time for it to play a greater role in annual physicals, especially in executive physical exams.
