Abstract Magnetic resonance guided high intensity focused ultrasound is a novel, non-invasive, image-guided procedure that is able to ablate intracranial tissue with submillimetre precision. It is currently FDA approved for essential tremor and tremor dominant Parkinson’s disease. The aim of this update is to review the limitations of current landmark-based targeting techniques of the ventral intermediate nucleus and demonstrate the role of emerging imaging techniques that are relevant for both magnetic resonance guided high intensity focused ultrasound and deep brain stimulation. A significant limitation of standard MRI sequences is that the ventral intermediate nucleus, dentatorubrothalamic tract, and other deep brain nuclei cannot be clearly identified. This paper provides original, annotated images demarcating the ventral intermediate nucleus, dentatorubrothalamic tract, and other deep brain nuclei on advanced MRI sequences such as fast grey matter acquisition T1 inversion recovery, quantitative susceptibility mapping, susceptibility weighted imaging, and diffusion tensor imaging tractography. Additionally, the paper reviews clinical efficacy of targeting with these novel MRI techniques when compared to current established landmark-based targeting techniques. The paper has widespread applicability to both deep brain stimulation and magnetic resonance guided high intensity focused ultrasound.

A small magnetic resonance imaging (MRI) study showed increased iron depositions in the periaqueductal grey matter in migraineurs, suggestive of a disturbed central antinociceptive neuronal network. With 1.5–T MRI, we assessed iron concentrations in seven deep brain nuclei in a large population-based cohort. We compared T2 values between migraineurs ( n = 138) and controls ( n = 75), with multivariate regression analysis. Analyses were conducted in age strata (< 50, n = 112; ≥ 50) because iron measures are increasingly influenced by non-iron-related factors in the older group. Overall, migraineurs and controls did not differ, nor did migraineurs with vs. without aura. In the younger migraineurs compared with controls, T2 values were lower in the putamen ( P = 0.02), globus pallidus ( P = 0.03) and red nucleus ( P = 0.03). Similarly, in these younger migraineurs, controlling for age, those with longer migraine history had lower T2 values in the putamen ( P = 0.01), caudate ( P = 0.04) and red nucleus ( P = 0.001). Repeated migraine attacks are associated with increased iron concentration/accumulation in multiple deep nuclei that are involved in central pain processing and migraine pathophysiology. It remains unclear whether iron accumulation in the antinociceptive network has a causative role in the development of (chronic) migraine headache.
