With the goal of shortening the overall scan time in pediatric MRI, here we present preliminary data acquired the use of four MR methods that have been built in-house: a T1-weighted 3D Short-Axis Propeller Echo Planar Imaging (SAP-EPI) sequence; a T2-weighted 3D SAP-EPI sequence, a novel Fluid Attenuated Inversion Recovery (FLAIR) Readout-Segmented (RS)-EPI sequence; and a dual-echo Diffusion-Weighted-Imaging (DWI) sequence. The first three of these methods are faster than their conventional counterparts; and the latter can also deliver R2 maps.
