Abstract

Introduction Investigation of the crossover sign (COS) in different degrees of tilt in pelvises made by three-dimensional printing of CT scans among patients with normal hip versions was carried out. Methods Radiology CT scans of 8 normal pelvises reconstructed in 3D and the effect of sequential tilting on the presence of the false-positive COS in 48 radiographs were investigated. Results The COS was seen in 77% of the AP radiographs during tilt changes. The average distance between the tip of the coccyx and the symphysis pubis was 32.06 ± 10.99 mm. Also, COSs were present in all radiographs from 6 degrees tilt and above. Conclusion Minor tilting of the pelvis can result in a false-positive crossover sign on AP plain radiographs.

三维打印骨盆模型交叉征的评价

本文对正常髋型患者的骨盆不同倾斜程度的交叉征(COS)进行了三维打印CT扫描的研究。方法回顾性分析8例正常骨盆三维重建的CT扫描结果，并对48张正常骨盆的顺序倾斜对假阳性COS的影响进行分析。结果倾斜改变时77%的AP片出现COS。尾骨尖端至耻骨联合的平均距离为32.06±10.99 mm。此外，所有倾斜6度及以上的x线片均出现COSs。结论骨盆轻微倾斜可导致AP平片假阳性交叉征象。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
