We combined the MP2RAGE sequence with a silent radial ZTE readout and acquired a high-contrast, high-SNR T1-weighted image and quantitative T1 map at 0.9mm isotropic resolution at 3T free from B1-inhomogeneity. This has potential for high resolution structural imaging of populations that would not otherwise tolerate MRI due to the acoustic noise of standard sequences.
