Magnetic resonance imaging (MRI) has been used for studying the dynamics of chick embryo development and growth. This can be repeated observations on the same embryo on a longitudinal basis, using high resolution ultra-high-field (7 Tesla or higher) MR scanners. MRI-based cell tracking using super-paramagnetic iron oxide (SPIO) particles provide an excellent means of cell monitoring in in-vivo. In this work, a novel sweep imaging with Fourier transformation (SWIFT) sequence, compared with conventional fast spin echo (FSE) and gradient-recalled echo (GRE) sequences, will be used to scan a chick embryo injected with SPIO nanoparticles.
