The aim of this study was to compare the paranasal sinus volumes obtained by manual and semiautomatic imaging software programs using both CT and CBCT imaging.
121 computed tomography (CT) and 119 cone beam computed tomography (CBCT) examinations were selected from the databases of the authors' institutes. The Digital Imaging and Communications in Medicine (DICOM) images were imported into 3-dimensonal imaging software, in which hand mode and semiautomatic tracing methods were used to measure the volumes of both maxillary sinuses and the sphenoid sinus. The determined volumetric means were compared to previously published averages.
Isometric CBCT-based volume determination results were closer to the real volume conditions, whereas the non-isometric CT-based volume measurements defined coherently lower volumes. By comparing the 2 volume measurement modes, the values gained from hand mode were closer to the literature data. Furthermore, CBCT-based image measurement results corresponded to the known averages.
Our results suggest that CBCT images provide reliable volumetric information that can be depended on for artificial organ construction, and which may aid the guidance of the operator prior to or during the intervention.
本研究的目的是比较使用CT和CBCT成像的手动和半自动成像软件程序获得的鼻窦体积。
从作者所在机构的数据库中选取121例计算机断层扫描（CT）和119例锥形束计算机断层扫描（CBCT）检查。将医学数字成像和通信（DICOM）图像导入三维成像软件，使用手动模式和半自动追踪方法测量上颌窦和蝶窦的体积。将确定的体积平均值与先前发表的平均值进行比较。
基于等距CBCT的体积测定结果更接近实际体积情况，而基于非等距CT的体积测量结果一致地定义了较低的体积。通过比较两种体积测量模式，手动模式获得的值更接近文献数据。此外，基于CBCT的图像测量结果与已知平均值相符。
我们的结果表明，CBCT图像提供了可靠的体积信息，可用于人工器官构建，并可能在干预前或干预期间帮助指导操作人员。
