摘要 【目的】探讨双能CT在体内尿路结石成分鉴别中的应用价值。【方法】选取2020年10月至2021年10月邵阳市中心医院收治的106例尿路结石患者,对其进行80 kV/140 kV双能量扫描及数据采集,分析尿路结石成分,以红外光谱作为金标准,绘制双能CT分析的受试者工作特征 (ROC)曲线,分析双能CT诊断的敏感度、特异度、准确度。【结果】双能CT对106例患者的126枚尿路结石进行成分分析,其中尿酸盐结石30枚,非尿酸盐结石96枚。离体后红外光谱诊断尿酸盐结石32枚,非尿酸盐结石94枚。双能CT与红外光谱评估不同成分结石比较,差异无统计学意义(χ2=0.228,P>0.05)。尿酸结石有效原子序数为7.06±0.68,与非尿酸结石的12.87±2.53比较,差异有统计学意义(t=-11.00,P<0.001)。双能CT分析结石成分的敏感度、特异度以及准确度分别为87.5%、97.9%及95.2%。【结论】双能CT能够较为准确地对尿路结石进行在体成分分析,有助于指导临床医师选择合适的治疗方式。

Abstract:【Objective】To explore the application value of dual energy CT in identifying the components of urinary calculi in vivo. 【Methods】 A total of 106 patients with urinary tract stones admitted to the Shaoyang Central Hospital from October 2020 to October 2021 were selected and subjected to 80 kV/140 kV dual energy scanning and data collection. The composition of urinary tract stones was analyzed,and infrared spectroscopy was used as the gold standard to draw the receiver operating characteristic (ROC) curve for dual energy CT analysis. The sensitivity,specificity,and accuracy of dual energy CT diagnosis were analyzed. 【Results】 Dual energy CT was used to analyze the composition of 126 urinary tract stones in 106 patients,including 30 urate stones and 96 non urate stones. 32 urate stones and 94 non urate stones were diagnosed by in vitro infrared spectroscopy. There was no statistically significant difference in the evaluation of different components of stones using dual energy CT and infrared spectroscopy (χ2=0.228,P>0.05). The effective atomic number of uric acid stones was 7.06 ± 0.68,while the effective atomic number of non uric acid stones was 12.87 ± 2.53,with a statistically significant difference (t=-11.00,P<0.001). The sensitivity,specificity,and accuracy of dual energy CT analysis of stone components were 87.5%,97.9%,and 95.2%,respectively. 【Conclusions】 Dual energy CT can accurately analyze the in vivo composition of urinary calculi,which helps guide clinical physicians to choose appropriate treatment methods.
