Published in Medical Imaging Week, December 8th, 2007
Research findings, 'Positive contrast visualization of iron oxide-labeled stem cells using inversion-recovery with ON-resonant water suppression (IRON),' are discussed in a new report. "In proton magnetic resonance imaging (MRI) metallic substances lead to magnetic field distortions that often result in signal voids in the adjacent anatomic structures. Thus, metallic objects and superparamagnetic iron oxide (SPIO)-labeled cells appear as hypointense artifacts that obscure the underlying anatomy," scientists writing in the journal Magnetic Resonance In Medicine report.
"The ability to illuminate these structures with positive contrast would enhance noninvasive MR...
