| 1 | Comparison of conventional radiography and MDCT in suspected scaphoid fractures显示文摘AIM: To determine the diagnostic accuracy and radiation dose of conventional radiography and multidetector computed tomography(MDCT) in suspected scaphoid fractures.METHODS: One hundred twenty-four consecutive patients were enrolled in our study who had suffered from a wrist trauma and showed typical clinical symptoms suspicious of an acute scaphoid fracture. All patients had initially undergone conventional radiography. Subsequent MDCT was performed within 10 d because of persisting clinical symptoms. Using the MDCT data as the reference standard, a fourfold table was used to classify the test results. The effective dose and impaired energy were assessed in order to compare the radiation burden of the two techniques. The Wilcoxon test was performed to compare the two diagnostic modalities.RESULTS: Conventional radiography showed 34 acute fractures of the scaphoid in 124 patients(42.2%). Subsequent MDCT revealed a total of 42 scaphoid fractures. The sensitivity of conventional radiography for scaphoid fracture detection was 42.8% and its specificity was 80% resulting in an overall accuracy of 59.6%. Conventional radiography was significantly inferior to MDCT(P < 0.01) concerning scaphoidfracture detection. The mean effective dose of MDCT was 0.1 m Sv compared to 0.002 m Sv of conventional radiography.CONCLUSION: Conventional radiography is insufficient for accurate scaphoid fracture detection. Regarding the almost negligible effective dose, MDCT should serve as the first imaging modality in wrist trauma. | Cyrus Behzadi Murat Karul Frank Oliver Henes Azien Laqmani Philipp Catala-Lehnen Wolfgang Lehmann Hans-Dieter Nagel Gerhard Adam Marc Regier | 2015 | World Journal of Radiology2015，7，1： | 4 |

| 7 | 新型检修井及管道评估体系在管线修复中的应用显示文摘首都地区水务局(CRW)于2013年底接管了哈里斯堡市下水道系统的所有权和维护保养工作,并承担了对上世纪六十年代后期联合下水道系统的维修和替换工作进行评估和优先排查的任务。CRW正在进行一个多阶段数据收集计划(Plan),以填补其GIS,增加其计算机化维护管理系统的有用性,并为其资产管理计划提供资金该计划其中一个阶段涉及到了国会大厦城综合污水系统的快速评估调查,其中包括检修井检查,以NASSCO MACP 2级格式收集的数据,并对检修井中所有管道进行变焦摄像机检查。本文介绍了所有考虑的评估技术,数据收集和可交付格式的要求,确保与GIS的兼容性,以及所取得的经验。该项目的优点包括收集检修井状况评估数据,GIS下水道系统连接以及提高由于塌陷,堵塞等导致的必要的紧急维护和修理工作的成本效益的方法。根据调查结果,CRW现在已经确定中央电视台检查和后续维修和替换工作优先顺序等计划。 | Marc Lehmann Jeff Bowra 王国城 | 2017 | 非开挖技术2017，0，5： | 0 |
