T2 weighted manufacturer standard adult 64mT sequence compared with reference 3T imaging and dedicated 64mT neonatal sequence. Term infant with small right-sided focal cortical infarction in the superior parietal lobe (red arrows). 3T MR scan was performed on day 15 and 64mT scan on day 21. 64mT adult sequence shows poor tissue contrast, the cortical infarct is not identifiable and there is asymmetric signal inhomogeneity (generalised left sided high T2). Subtle abnormal cortical signal is present on the optimised 64mT neonatal sequence in the location of the infarct. Deep grey matter on axial plane and cerebellum on coronal plane remain unclear and PLIC not identified due to persistent noise and narrow contrast. PMA: post-menstrual age; PLIC: posterior limb of the internal capsule.
