By controlling the size and lattice distortion of CaF2 nanocrystals, we accelerated their longitudinal relaxation, addressing the issue of unacceptable scanning time in MR imaging.
As a promising F-19 MRI tracer, the relatively slow lattice-spin relaxation of CaF2 nanocrystals leads to an unacceptable scanning time in MR imaging, hampering their application. We herein controlled the size and lattice distortion of CaF2 nanocrystals and showed that the shortened interplanar spacing pronouncedly sped up the longitude relaxation.
