Imaging of the microvascular distribution in the mandibular bone marrow using Dual Energy Computed Tomography Imaging; a trial run

目的是利用双能CT成像(DEI)对下颌骨骨髓内的微血管分布进行成像。研究对象为下颌骨组织病理学标本和下颌骨病变切除患者的术前CT图像。组织学标本的骨髓内微血管分布的范围被主观地评估。将术前CT图像生成的多平面重建图像与组织学结果进行比较。用来分析下颌骨骨髓微血管形成的最佳CT图像并不能令人满意。即使使用DEI，在CT图像上显示的骨髓面积也非常小。组织学图像上脂肪组织面积明显大于微血管分布面积。可想而知，这种微血管形成并不能使CT图像上的密度变化明显。

The aim was imaging of the microvascular distribution in the mandibular bone marrow using Dual Energy CT Imaging (DEI). Histopathological specimens of the mandibular bone and pre-operative CT images from the patients who underwent the resection of the mandibular disease were used. The extent of the microvascular distribution within the bone marrow on the histological specimen was subjectively assessed. Multi-Planar Reconstruction Images generated from the pre-operative CT images were compared with the histological findings. Creation of optimal CT images for analysis of the microvascularization in the bone marrow of the mandible was unsatisfactory. The bone marrow area was extremely small to visualize on CT images even with DEI. The area of adipose tissue was predominantly larger than that of microvessels distribution on histological images. It was conceivable that such microvascularization could not make the clear density variations on CT images.
