宝石能谱CT低剂量扫描肺癌诊断中应用价值探析

Application Value of Gemstone Energy Spectrum CT Low Dose Scanning in Diagnosis of Lung Cancer

目的探讨宝石能谱CT低剂量扫描肺癌诊断中应用价值。方法选择6我院2018年6月至2021年6月收治的60例疑似肺癌患者,入选者均进行常规CT、宝石能谱CT低剂量检查。以病理检查为金标准,分析常规CT、宝石能谱CT诊断肺癌的价值,并计算宝石能谱CT低剂量扫描诊断结果与病理检查结果的一致性,另外比较CT平扫与宝石能谱CT低剂量扫描参数。结果60例疑似肺癌患者经病理或穿刺活检发现37例确诊为肺癌,剩余23例为良性病变;宝石能谱CT低剂量扫描诊断肺癌的灵敏度[94.59%(35/37)]、特异度[95.65%(22/23)]、准确度[95.00%(57/60)]、阳性预测值[97.22%(35/36)]、阴性预测值[91.67%(22/24)]均高于常规CT(72.97%、65.22%、70.00%、77.14%、60.00%),差异有统计学意义(P<0.05);宝石能谱CT低剂量扫描诊断结果与病理检查结果的一致性较高(Kappa=0.895,P<0.05);宝石能谱CT低剂量扫描参数均低于常规CT,有统计学差异(P<0.05)。结论宝石能谱CT低剂量扫描在肺癌诊断中具有较高的应用价值,能够明确病变性质,为后续治疗提供更多参考,值得临床广泛应用。

Objective To explore the value of gemstone energy spectrum CT in the diagnosis of lung cancer.Methods 60 patients with suspected lung cancer who were admitted to our hospital from June 2018 to June 2021 were selected.All the selected patients underwent routine CT and gemstone energy spectrum CT low-dose examination.Taking pathological examination as the gold standard,the value of routine CT and gemstone energy spectrum CT in the diagnosis of lung cancer was analyzed,and the consistency between the diagnosis results of low-dose gemstone energy spectrum CT and pathological examination results was calculated.In addition,the parameters of plain CT and low-dose gemstone energy spectrum CT were compared.Results 37 of 60 patients with suspected lung cancer were diagnosed as lung cancer by pathology or puncture biopsy,and the remaining 23 were benign lesions;The sensitivity[94.59%(35/37)],specificity[95.65%(22/23)],accuracy[95.00%(57/60)],positive predictive value[97.22%(35/36)],and negative predictive value[91.67%(22/24)]of gem energy spectrum CT low-dose scanning in the diagnosis of lung cancer were higher than those of conventional CT(72.97%,65.22%,70.00%,77.14%,60.00%).The difference was statistically significant(P<0.05);The diagnostic results of gemstone energy spectrum CT low-dose scanning were consistent with those of pathological examination(kappa=0.895,P<0.05);The parameters of gemstone energy spectrum CT low-dose scanning were lower than those of conventional CT(P<0.05).Conclusion gemstone energy spectrum CT low-dose scanning has high application value in the diagnosis of lung cancer,which can clarify the nature of the lesion and provide more reference for follow-up treatment.It is worthy of wide clinical application.
