摘要

目的:利用Hounsfield单位(HU)和多层计算机断层扫描(CT)评估上颌和下颌骨骨密度(BMD)与颈椎骨密度的相关性,验证CT是否可以作为一种有用的骨质疏松筛查工具。方法:对79例同时行上颌骨、下颌骨和颈椎CT检查的患者进行多层螺旋CT检查。评估左、右解剖区域:下颌骨分支;下颌骨头;下第一磨牙下面的区域和上尖牙下面的区域。利用位于切片中心的0.1 cm感兴趣区域(ROI)测量每个区域的HU。结果:颈椎与下颌骨后区有显著相关性,上颌骨前区与颈椎也有显著相关性。然而,颈椎与下颌骨的其他部位,如下颌支和下颌头之间没有相关性。结论:上颌前骨和下颌骨后骨HU值与颈椎HU值相关,可作为骨质疏松症的筛查工具。

Opportunistic screening for osteoporosis correlating the bone densities of jaws with multislice computed tomography for cervical vertebrae
Objectives: to evaluate the correlation of the bone mineral density (BMD) from maxilla and mandible with that of the cervical vertebrae, using Hounsfield units (HU) and multislice computed tomography (CT) to verify whether CT could be a useful osteoporosis screening tool. Methods: 79 multislice CT examinations from patients who underwent CT examinations of maxilla, mandible and cervical vertebrae simultaneously were included. The following left and right anatomical regions were assessed: mandible ramus; mandible head; the area below the inferior first molar and the area below the upper cuspids. HU were measured in each area using a 0.1 cm region of interest (ROI) positioned in the center of the slice. Results: a significant correlation between the cervical spine and the posterior region of the mandible was found, as well as a significant correlation between the anterior maxilla and the cervical spine. However, no correlation was found between the cervical spine and other parts of the mandible, such as ramus and head of mandible. Conclusions: As anterior maxillary bone and posterior mandible bone HU values correlate with cervical bone HU values, this examination may be applied as osteoporosis screening tool.
