双能CT成像在痛风诊断中应用效果分析

The Effect to the Diagnosis of Tophi with Dual-energy CT Imaging

目的观察双能量CT在痛风石成像诊断中的应用效果。方法整群选择2013年5月—2014年8月间在黑龙江省医院CT室进行检查的47例有关节痛并怀疑痛风患者资料作为研究对象,所有患者均行痛风"金标准"检查,均具有双能量CT检查资料,记录诊断准确性。结果 47例具有痛风金标准检查资料的患者经过双能CT检查经过图像后处理及痛风分析后,有43例存在绿色痛风结石,诊断符合率为91.5%,与金标准资料比较(χ2=2.261,P=0.152),差异无统计学意义。结论双能量CT检测痛风石在临床痛风诊断中具有较高的应用价值,是一种新型影像检查技术,在临床具有较大的应用空间及发展潜力。

Objective To Observe of the tophi diagnosis with dual-energy CT imaging. Methods Selected 47 patients with pain and suspected gout patient data as a study from May 2013 to August 2014 in the Heilongjiang Provincial Hospital CT rooms for all patients underwent gout ＂gold standard＂ inspection, all with dual-energy CT check the information on the diagnostic accuracy of records. Results 47 patients had gout gold standard examination data through dual-energy CT examination after image post-processing and analysis of gout, there were 43 cases of gout presence of green stones, diagnosis rate was 91.5%, with the gold standard data were compared（χ^2=2.261,P=0.152）, not statistically significant. Conclusion Dual-energy CT tophi detection with high clinical value, is a new imaging technique in clinical applications of space and has a large potential for development.
