In Vivo Magic Angle Magnetic Resonance Imaging for Cell Tracking in Equine Low-Field MRI

Figure 1

Position of the equine limb in the MRI scanner. (a) and (b) show the equine limb positioned between the poles of an equine-dedicated low-field MRI system. In (a), the SDFT of a left forelimb (posterior limb) was positioned in approximately the magic angle () to the main magnetic field . In (b), the SDFT of a right forelimb was positioned in a angle (standard series) to the main magnetic field . (c) and (d) show T1-weighted magic angle (c) and standard (d) images of healthy SDFT (arrows) in the midmetacarpal region. The signal intensity of the SDFT in the magic angle image increases compared to the SDFT in the standard image.
