摘要
目的:分析256排Revolution CT能谱扫描在尿路结石成分检出中的应用价值。方法:选取2023年9月—2024年10月在景德镇市第一人民医院接受256排Revolution CT能谱扫描的80例尿路结石患者为研究对象,在患者完成尿路取石或排石后对结石标本进行化学分析,以红外光谱分析结果为金标准,观察256排Revolution CT能谱扫描检测尿路结石成分的价值。结果:经红外光谱分析结果显示检出的尿路结石含3种类型,共102枚,包括纯尿酸结石15枚、非纯尿酸结石19枚、混合结石68枚。256排Revolution CT能谱扫描诊断纯尿酸结石、非纯尿酸结石、混合结石的敏感度分别为100%、68.42%、94.12%;特异度对应为100%、95.18%、82.35%;借助红外光谱分析仪通过结石分析图、有效原子序数分为纯尿酸结石15枚、草酸钙结石12枚、碳酸磷结石3枚、磷酸铵镁结石2枚、磷酸钙结石2枚、混合性结石68枚;256排Revolution CT能谱扫描共检出纯尿酸结石15枚、草酸钙结石10枚、碳酸磷结石1枚、磷酸铵镁结石1枚、磷酸钙结石1枚、混合性结石64枚,检出准确率分别为100%、83.33%、33.33%、50.00%、50.00%、94.12%。结论:256排Revolution CT能谱扫描对尿路结石成分分析具有临床意义,可对纯尿酸结石、非纯尿酸结石及混合结石给予区分。
Objective:To analyze the application value of 256-slice Revolution CT energy spectrum scanning in the detection of urinary tract calculi components.Method:A total of 80 patients with urinary tract calculi who underwent 256-slice Revolution CT energy spectrum scanning at the First People's Hospital of Jingdezhen from September 2023 to October 2024 were selected as the research subjects.Chemical analysis was conducted on the calculi specimens after the patients completed urinary tract calculi removal or calculi expulsion,and the results of infrared spectroscopy analysis were taken as the gold standard.The value of 256-slice Revolution CT energy spectrum scanning in detecting the components of urinary tract calculi was observed.Result:The results of infrared spectroscopy analysis showed that the detected urinary tract calculi contained three types,totaling 102 pieces,including 15 pure uric acid calculi,19 non-pure uric acid calculi,and 68 mixed calculi.The sensitivities of 256-slice Revolution CT energy spectral scanning in diagnosing pure uric acid calculi,non-pure uric acid calculi and mixed calculi were 100%,68.42%and 94.12%respectively;the corresponding specificities were 100%,95.18%,and 82.35%.With the help of an infrared spectrometer,the calculi were classified into 15 pure uric acid calculi,12 calcium oxalate calculi,3 phosphorus carbonate calculi,2 magnesium ammonium phosphate calculi,2 calcium phosphate calculi and 68 mixed calculi based on the analysis diagrams and atomic effective numbers.A total of 15 uric acid calculi,10 calcium oxalate calculi,1 phosphorus carbonate calculi,1 magnesium ammonium phosphate calculi,1 calcium phosphate calculi and 64 mixed calculi were detected by 256-slice Revolution CT spectral scanning.The detection accuracy rates were 100%,83.33%,33.33%,50.00%,50.00%and 94.12%respectively.Conclusion:256-slice Revolution CT energy spectral scanning has clinical significance for the component analysis of urinary tract calculi and can distinguish pure uric acid calculi,non-pure uric acid calculi and mixed calculi.
