摘要
目的探讨宝石能谱电子计算机断层扫描技术(CT)在食管癌术前评估中的应用价值。方法回顾性选取2019年3月至2021年2月间咸阳市第一人民医院收治的98例食管癌患者,均应用宝石能谱CT成像技术进行检查。根据WHO消化系统肿瘤病理学和遗传学标准观察病理结果,分为高分化组22例、中分化组41例和低分化组35例。比较三组患者定性参数特征(肿瘤直径、部位)、不同单能量水平的CT值及基物质碘浓度、水浓度与标准化碘基值(NIC)。结果三组患者肿瘤直径和肿瘤部位比较,差异均无统计学意义(P>0.05)。三组患者不同单能量水平下CT值比较,差异均有统计学意义(均P<0.01),即低分化组50keV、70 keV、90 keV、110 keV、130 keV下CT值>中分化组>高分化组。低分化组患者碘浓度和NIC值高于中分化组与高分化组,差异均有统计学意义(均P<0.01);中分化组和高分化组碘浓度和NIC值比较及三组患者水浓度比较,差异均无统计学意义(P>0.05)。结论宝石能谱CT成像技术在食管癌术前评估中具有较好的应用价值,可有效鉴别肿瘤的分化程度,为手术方案提供有利参考。
Objective To explore the application value of gemstone energy spectrum computed tomography(CT)in preoperative evaluation of esophageal cancer.Methods The data of 98 patients with esophageal cancer were retrospectively investigated at Xianyang First People’s Hospital from March 2019 to February 2021.All patients underwent scanning with gemstone spectral CT imaging.World Health Organization(WHO)classification of digestive system tumor and genetics standards were used to observe the results of a pathology test,the patients were divided into a high differentiation group(22 patients),a medium differentiation group(41 patients)and a low differentiation group(35 patients).Qualitative parameters including tumor size and tumor location,CT values on different single energy levels,iodine concentration of iodine-containing substance,water concentration and normalized iodine base value(NIC)were compared among the three groups.Results There was no significant difference in tumor size and location among the high,medium and low differentiation groups(P>0.05).The difference of CT value on different single energy levels was statistically significant among the three groups(P<0.05).That is CT value on 50 keV,70 keV,90 keV,110 keV and 130 keV was higher in low differentiation group than in the medium differentiation group followed by high differentiation group.The iodine concentration and NIC value were higher in the low differentiation group than in the medium differentiation group and the high differentiation group(all P<0.05).However,there was no significant difference in iodine concentration and NIC value between the medium differentiation group and the high differentiation group(P>0.05).There was no significant difference in water concentration among the three groups(P>0.05).Conclusion Gemstone spectral CT imaging has significant application value in preoperative evaluation of esophageal cancer,which can effectively identify the different degrees of tumor differentiation and provide a favorable reference for the surgical plan.
