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.
People who live in rural America may deserve the same quality healthcare as anyone living in the U.S., but it is not...
Scientists at Rice's Laboratory for Nanophotonics added iron chelates (blue) and fluorescent dye (red) to multi-layered gold nanomatryoshkas to create particles that can be used for disease therapy and diagnostics. The "theranostic" nanoparticles have a core of gold (left) that is covered by silica containing the diagnostic iron and dye, which is covered by an outer shell of gold. The particles are about 20 times smaller than a red blood cell, and by varying the thickness of the layers, LANP scientists can tune the nanomatryoshkas to convert light into cancer-killing heat.

Contrast agents improve every kind of medical image from computed tomography (CT) to magnetic resonance imaging (MR...
Access to healthcare by rural-living Americans can be difficult.
A new artificial-intelligence-based approach to image reconstruction, called AUTOMAP, yields higher quality images from less data, reducing radiation doses for CT and PET and shortening scan times for MRI. Shown here are MR images reconstructed from the same data with conventional approaches, at left, and AUTOMAP, at right. Athinoula A.
