摘　　要：目的 探讨能谱CT在诊断痛风石与增生钙化中的应用价值。方法 选取2019年8月至2020年9月本院收治的98例疑似痛风患者,所有患者均行能谱CT扫描,观察患者痛风石与增生钙化显示情况。结果 98例患者71例确诊为痛风,能谱CT检出痛风石灵敏度95.77%、特异度88.89%、准确率93.88%均高于常规CT的69.01%、62.96%、67.35%,差异有统计学意义(P<0.05);能谱CT骨质破坏、关节积液、软组织肿胀检出率分别为77.55%、54.08%、2 9.59%均高于常规CT的64.29%、39.80%、17.35%,差异有统计学意义(P<0.05)。结论 能谱CT定量分析在痛风石与增生钙化诊断中应用价值较高,可提高诊断准确率,帮助临床医师判断病情为治疗提供依据。Objective To investigate the application value of energy spectrum CT in the diagnosis of tophus and hyperplasia calcification.Methods 98 patients suspected of gout who were admitted to the hospital from August 2019 to September 2020 were selected.All patients were subjected to energy spectrum CT scanning to observe the tophi and hyperplasia calcification.Results 71 of the 98 patients were diagnosed as gout.The sensitivity,specificity and accu racy of energy spectrum CT in detecting tophus were 95.77%,88.89%,and 93.88%,which were higher than those of conventional CT(69.01%,62.96%,and 67.35%)(P<0.05).The detection rates of bone destruction,joint effusion,and soft tissue swelling by energy spectrum CT were 77.55%,54.08%,and 29.59%,which were higher than those by conventional CT(64.29%,39.80%,and 17.35%)(P<0.05).Conclusion Quantitative analysis of energy spectrum CT is of high value in the diagnosis of tophus and hyperplasia calcification,which can improve the diagnostic accuracy,help clinicians to judge the patients’ condition,and provide a basis for treatment.
