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.

fMRI shows low dose of methylene blue improves short-term memory

Methylene blue has been around for nearly a century and is mostly used to treat methemoglobinemia. New data, however, suggests that a single dose of methylene blue enhances the response of brain regions that control attention and short-term memory.

MRI findings measuring loneliness could enhance early detection of Alzheimer's

MRI scans done on patients measured if loneliness is associated with levels of amyloid proteins in the brain, which researchers suggest could be an indication of preclinical Alzheimer’s disease and ultimately aid in intervention research.

Fetal MRI: A possibility at last

Researchers form several Boston-area universities have developed an MRI algorithm that can account for the constant movement of the fetus and mother, possibly giving clinicians the ability to measure levels of chemicals in the placenta and fetal organs--an important diagnostic marker.

"This was an unneeded burden, which was solely adding to the administrative hassles of medicine," said American Society of Nuclear Cardiology President Larry Phillips.

SCAI and four other major healthcare organizations signed a joint letter in support of intravascular ultrasound. 

The newly approved AI models are designed to improve the detection of pulmonary embolisms and strokes in patients who undergo CT scans.
