PURPOSE
The aim of the present study was to analyze the diagnostic value of some temporal bone structures, e.g., ossicular chain, with digital volume tomography (DVT) compared with computed tomography (CT).
METHODS
Radiological imaging for presentation structures of the temporal bone were performed by DVT and CT. Axial and coronal scans in vitro examinations were performed in 38 human temporal bones. 43 structures were defined. The frequency of visualization of these anatomic structures were studied and statistically analyzed.
RESULTS
In the present study there was a higher significance of identified structures in DVT. In 15 (34.9%) temporal bone specimens defined structures were found equally in DVT and CT scans of axial images and 12 (27.9%) of coronal images. However, 9 structures (20.1%) of axial scans and 5 structures (11.6%) of coronal scans could be identified statistically significantly (P < 0.05) more often in DVT than in CT.
CONCLUSION
Anatomical structures of the temporal bone can be identified in higher significance in DVT than in CT scans.
目的
本研究旨在分析数字容积断层扫描（DVT）与计算机断层扫描（CT）相比，某些颞骨结构（如听骨链）的诊断价值。
方法
通过DVT和CT对颞骨的呈现结构进行放射成像。对38块人类颞骨进行了体外轴向和冠状扫描检查。定义了43个结构。研究并统计分析了这些解剖结构的可视化频率。
结果
在本研究中，DVT中识别出的结构具有更高的显著性。在15块（34.9%）颞骨标本中，轴向图像的DVT和CT扫描以及冠状图像的12块（27.9%）中均发现了定义的结构。然而，轴向扫描的9个结构（20.1%）和冠状扫描的5个结构（11.6%）在DVT中比在CT中更常被统计学显著识别（P < 0.05）。
结论
与CT扫描相比，DVT能更显著地识别颞骨的解剖结构。
