Thalamic nuclei are typically invisible on conventional T1 and T2 MRI. We propose here an anatomical atlas based on 7T White matter nulled MP-RAGE data which can be used for a variety of applications including targeting the VIM nucleus for neurosurgical applications and thalamic nuclear volumetry for tracking disease progression using conventional MRI sequences like MP-RAGE or FLAIR.
