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.

AI turns low-quality MRI scans into helpful heart images
A team of biomedical engineers, radiologists and cardiologists has developed a new AI model capable of restoring low-quality cardiac MRI scans.
New AI-enabled, helium-free MRI system earns FDA clearance
The scanner requires just 0.7 liters of liquid helium for cooling—a fraction of the more than 1,500 liters standard systems need to operate safely.
Low dose GBCA effective, safe for pediatric imaging
Although gadopiclenol is approved for adults and children ages 2 and older, there is limited data on its use in the pediatric population.
Bayer seeks FDA approval for gadoquatrane, its latest low-dose GBCA
The investigational agent uses 60% less gadolinium without sacrificing image quality, according to recent clinical trial findings.
Signs of Alzheimer's evident on imaging up to 15 years prior to symptom onset in Down syndrome population
By identifying these structural changes prior to the onset of symptomatic neurodegeneration, providers may be able to initiate preventive therapies sooner.
