Many image contrasts are necessary in clinical magnetic resonance imaging (MRI) including qualitative and quantitative images, which traditionally take a long acquisition time. STrategically Acquired Gradient Echo (STAGE)^1,2,3 is a rapid imaging method which can acquire multiple qualitative and quantitative images with good resolution and SNR in just 5 minutes at 3T. In this work, the STAGE concept is optimized, and further extended to 1.5T. A total of 11 high quality clinically meaningful images, and 2 field maps, were produced with 0.67x1.33x2.7 mm³ resolution in a single 9-min scan on a NMS 1.5T system covering the whole brain.
