Mini magnets injected into the body, microscale magnetic particles (top) could yield colored magnetic resonance images
Magnetic resonance imaging (MRI) is a clinical workhorse, producing exquisitely detailed 3-D pictures of tumors, blood vessels, bones, and structures deep inside the body. MRI images are in shades of gray, and their contrast is based on how much water is in the part of the body under study. Now physicists have fabricated miniature magnetic particles that could brighten MRI with a rainbow of colors that convey a wealth of information about the disease states and behavior of tissues in the body.
