| Research Abstract |
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.
