小鼠脑血管系统的体内成像通常需要应用颅骨开窗技术:开放颅骨颅窗或薄化颅骨颅窗。我们报告了 C57/BL 小鼠的非侵入性 3D 体内脑血流成像,通过使用超高灵敏度光学微血管造影 (UHS-OMAG) 和多普勒光学微血管造影 (DOMAG) 技术,根据其程序和可视化表面软膜血管动态的能力来评估两种颅窗类型。应用薄化颅骨技术可有效获得软脑膜血管的高质量图像以进行短期成像,并且在可用成像面积、手术效率和脑环境保存方面比开放颅骨技术具有优势。总之,薄颅骨颅窗是使用 OMAG 或其他 OCT 血流成像方式研究软脑膜微血管系统血流动力学的有前途的工具。
In vivo imaging of mouse brain vasculature typically requires applying skull window opening techniques: open-skull cranial window or thinned-skull cranial window. We report non-invasive 3D in vivo cerebral blood flow imaging of C57/BL mouse by the use of ultra-high sensitive optical microangiography (UHS-OMAG) and Doppler optical microangiography (DOMAG) techniques to evaluate two cranial window types based on their procedures and ability to visualize surface pial vessel dynamics. Application of the thinned-skull technique is found to be effective in achieving high quality images for pial vessels for short-term imaging, and has advantages over the open-skull technique in available imaging area, surgical efficiency, and cerebral environment preservation. In summary, thinned-skull cranial window serves as a promising tool in studying hemodynamics in pial microvasculature using OMAG or other OCT blood flow imaging modalities.
