In MRI spin echo (SE) pulse sequences are used to eliminate magnetic field inhomogeneity effects and create T2 contrast. However, SE techniques suffer from a number of artifacts including restrictions on RF power deposition limiting their clinical applications especially at high field MRI. In this study we demonstrate in vivo application of FID-based technique - Gradient Echo Plural Contrast Imaging (GEPCI) that also allows elimination of magnetic inhomogeneity effects and does not suffer from restrictions on RF power. The technique allows generation of T2, T2*, T1 and spin density images in a single scan, hence the title Plural Contrast Imaging.
