Abstract
The development of neuroimaging has allowed clinicians to improve clinicoanatomic correlations in patients with strokes. Brainstem and cerebellum structures are well delineated on MRI, but there is a lack of standardization in their arterial supply. We present a system of 12 brainstem and cerebellum axial sections, depicting the dominant arterial territories and the most important anatomic structures. These sections may be used as a practical tool to determine arterial territories on MRI, and may help establish consistent clinicoanatomic correlations in patients with brainstem and cerebellar ischemic strokes.
