The dentate nucleus is most easily identified on T2 and particularly T2* weighted sequences (e.g. SWI) as an undulating semicircular structure, the opening facing the midline. It is usually difficult to identify on T1 weighted images.
Recently, there has been significant interest in gadolinium deposition in the dentate nucleus, which becomes readily visible on T1 weighted images in patients who have received multiple doses of gadolinium containing contrast agents 3.
