Universal Pulses (UP) were recently proposed as a plug-and-play pTx solution. To extend the so-called PASTeUR package of anatomical sequences with a mapping technique, we focused on a MP2RAGE acquisition that has shown to be robust against receive profiles when acquired at 7T in single channel transmission. UP provide the advantage of intrinsically correcting for flip angle variations throughout the brain, leading to an increased SNR in regions usually left with low B1+ intensity. Moreover, T1 quantification can be obtained without the need for B1+ acquisition and additional post-processing.
