Acquiring high-resolution diagnostic pediatric MR images is challenging due to patient movement during long scan times, resulting in spatial blurring and motion artifacts. Developing rapid acquisition methods is essential to obtaining diagnostic-quality MR images. Recently, an echo planar imaging (EPI)-based Multi-Inversion Spin and Gradient Echo (MI-SAGE) sequence was reported to acquire multiple tissue contrasts from adult brains with a single 1-minute scan. This study demonstrates the utility of a 1-minute MI-SAGE acquisition in pediatric subjects to generate clinically relevant synthetic image contrasts (T1w, T2w, T2*w) from quantitative relaxometry maps (T1, T2, and T2*).
