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.

Simulations by Rice University engineers have revealed details about the molecular interactions between gadolinium contrast agents used in MRI scans and their liquid environment. In this model, green gadolinium is surrounded by blue chelate ions, themselves surrounded by water (gray oxygen and red hydrogen atoms). Thiago Pinheiro dos Santos/Rice University

Figure 1. Group analysis on susceptibility-weighted imaging exhibiting higher susceptibility-weighted imaging values in the COVID group when compared to healthy controls. Three significant clusters were found primarily in the white matter regions of the pre-frontal cortex and in the brainstem. The clusters (a) and (b) are observed bilaterally in the cerebral white matter near the orbitofrontal gyrus, whereas (c) lies in the midbrain region.
