Magnetic Resonance Imaging (MRI)

MRI creates images from the magnetic resonance created in hydrogen atoms when they are polarized and an electromagnetic pulse is used to knock them off axis. This section includes MR analysis software, MRI scanners, gadolinium contrast agents and related magnetic resonance imaging accessories.

#coronavirus #COVID19 #pandemic Face masks may contain metallic components, both visible and hidden, which in the magnetic resonance imaging (MRI) environment may pose a hazard. The role of face masks in infection control is recognized and their use should not be avoided as simple practices can avoid these hazards.

The first known study exploring optimal outpatient exam scheduling through a model algorithm was shown to yield shorter wait times for magnetic resonance imaging (MRI) for patients and reduced costs. A collaboration including experts at Lahey Hospital & Medical Center (LHMC) and at the Thayer School of Engineering at Dartmouth College worked to identify sources of delays for MRI procedures at LHMC in order to develop a mathematical model to optimize scheduling.

(b) 3D MRI brain vascular map using Dotarem (gadolinium-based contrast agent). Resolution is low and microvessels are not visible. (c) For 3D reconstruction, multiple slices of MRI images of the rat heart were obtained after injection of SAIO. Rat coronary arteries (180 microns) which are 10 times thinner than human coronary arteries were successfully visualized. Coronary arteries supply blood to the heart muscle and the blockage or narrowing of such arteries causes myocardial infarction or angina, but visualizing these arteries was impossible due to the limited resolution of current MRI contrast agents.
