Rapid imaging of endogenously labeled neuroprogenitor cells in the rat brain is shown using high-field MRI and efficient Steady-State Free Precession sequences. A RF-phase cycle progression based on the Golden Angle is used to produce Linear Combination SSFP (LCSSFP) images without banding artifacts. The method yields high resolution images with few global distortions suitable for cell tracking and calculating relaxation images.
