T2W MRI is useful for lesion detection in neurological disorders. At 7T, while SNR can be excellent for high-resolution imaging, T2W imaging is known to be difficult due to problems with B1 amplitude and homogeneity, as well as low T2 contrast between WM vs. GM. To address these, we developed new simultaneous T1W/T2W MP2RAGE sequence. We simulated the new sequence to optimize brain contrast and implemented on 7T combined with B1-shimmed pTx multi-transceiver and high-order B0 shim. The results show homogeneous contrast of WM vs. GM over whole brain with excellent SAR efficiency, giving high resolution detection of hippocampal sub-structures.
