- Reposted by Nikos PriovoulosA new MRI protocol can scan the human brain and its venous network in under 7 minutes at 0.35 mm iso. resolution, marking it as a potential tool for diagnosing cerebrovascular diseases and monitoring neurodegeneration. scim.ag/3LkRfRY
- 🎓🧠 It's finally out in @pnas.org 📄 doi.org/10.1073/pnas... We reconstruct the cerebellar cortex and vasculature in-vivo by combining motion-corrected, pTX-enabled #7T MRI with a new segmentation approach.
- Until recently, getting a reliable in-vivo approximation of the human cerebellar cortex was out of reach.
- We observe a convergent interlobular gradient in cortical thickness and vascular-density. This heterogeneity seems driven by the granular layer cytoarchitecture when comparing to 3D histology. Still work to be done though to further improve SNR and segmentation fidelity.
