Cellular
imaging is an important and growing field in magnetic resonance. The ability
to non-invasively detect the trafficking and accumulation of cells in vivo has
broad implications for both a better understanding of biological processes
and the development of novel treatments for numerous conditions. Here explore
using post processing techniques called Phase map cross-correlation Detection
and Quantification or PDQ for detection and quantification of single
MPIO-labeled cells in vivo. PDQ uses phase information to calculate a
magnetic dipole moment for each detected cell. This information can be used to correlate
labeled cell between serial scans and imaging methods.
