TR= 4330ms, TI1\/TI2=750\/2370ms, TE=2.8ms, flip angle=5,6, and GRAPPA = 3. The image matrix was typically 256x300x320 or 420x378x288 but was dependent upon coverage and FOV. The MP2RAGE denoised images [6, 7] were intensity-normalised using a histogram clamping technique.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<p>6.
