基于断层融合技术对骨折术后骨痂显示的对照观察

目的观察X线断层融合技术与数字摄影在骨折术后愈合进程中骨痂显示的差异。 方法54例骨折术后患者，分别于术后2周、1个月、2个月和3个月均行数字摄影和X线断层融合技术成像，对比两种检查方法获得的图像并作相应的统计学分析。 结果54 例患者中，X线断层融合技术和数字摄影两种方法所获得图像对骨痂的显示情况在术后2 周显示率分别为3.7%和14.81%，有显著差异（P<0.05），术后1 个月显示率分别为38.89%和77.78%，有显著差异（P<0.05），术后2 个月显示率分别为66.67%和87.04%，有显著差异（P<0.05），术后3个月显示率分别为88.89%和94.44%，无显著差异（P>0.05）。 结论X线断层融合技术对骨折术后早期骨痂显示具有重要的价值，较X线平片具有明显优势。  

A Comparative observation of callus after surgery for fractures based on Digital Tomosythesis

Objective To observe the differences of the detection of callus in the early healing process after surgery of fractures between Digital Tomosynthesis (DTS) and Digital Rdiography (DR). Methods A total of 54 patients were performed on DR and DTS imaging after 2 weeks, 1 month, 2 months and 3 months of surgery for fractures and the obtained images were compared. Results In 54 patients, the detection rates of callus by DTS and DR were 3.7% and 14.81% respectively at the second week with significant difference (P<0.05), 38.89% and 77.78% after 1 month with significant difference (P<0.05), 66.67% and 87.04% at the 2 months with significant difference(P<0.05), and 88.89% and 94.44% at the 3 months, without significant difference(P>0.05). Conclusion DTS has an important value for the early detection of callus after surgery for fractures, which has more obvious advantages over the X-ray plain film.
