摘要:
目的 研究CT、MRI影像联合应用对直肠癌临床术前分期及淋巴结阳性诊断准确率的价值。方法 选取2020年6月-2021年6月在我院诊治的84例直肠癌患者为研究对象，采用CT、MRI、CT联合MRI检查，以术后病理分期为金标准，比较不同检测方法对直肠癌术前分期诊断准确率、总准确率、淋巴结阳性诊断准确率，分析CT、MRI、CT联合MRI 检查对直肠癌术前分期和淋巴结阳性诊断准确率与病理结果的一致性。结果 CT联合MRI对直肠癌T1~T2期、T3期、T4期的准确率高于CT、MRI检测，且MRI对直肠癌T1~T2期、T3期的准确率高于CT，差异有统计学意义（P＜0.05）；CT联合MRI检查直肠癌的总准确率、淋巴结阳性诊断准确率均高于CT、MRI，且MRI高于CT，差异有统计学意义（P＜0.05）；MRI对直肠癌的术前分期诊断和淋巴结阳性诊断准确率与病理结果一致性均高于CT，差异有统计学意义（P＜0.05），CT联合MRI对直肠癌的术前分期诊断和淋巴结阳性诊断准确率与病理结果具有高度一致性，且一致性高于CT、MR检查，差异有统计学意义（P＜0.05）。结论 CT、MRI影像联合运用可提高直肠癌临床分期准确率和淋巴结阳性诊断准确率，对直肠癌临床术前制定治疗方案、判断淋巴结的转移提供可靠的依据，值得临床应用。
Abstract:
Objective To study the value of CT and MRI combined application in the preoperative staging of rectal cancer and the accuracy of lymph node positive diagnosis.Methods A total of 84 patients with rectal cancer diagnosed and treated in our hospital from June 2020 to June 2021 were selected as the research objects. CT, MRI, CT combined with MRI were used, and the postoperative pathological staging was taken as the gold standard, the accuracy rate of preoperative staging, total accuracy rate and lymph node positive diagnosis accuracy of different detection methods for rectal cancer were compared. The consistency between the accuracy rate of preoperative staging and lymph node positive diagnosis of rectal cancer by CT, MRI, CT combined with MRI and the pathological results was analyzed.Results The accuracy of CT combined with MRI in T1-T2, T3 and T4 stages of rectal cancer was higher than that of CT and MRI, and the accuracy of MRI in T1-T2 and T3 stages of rectal cancer was higher than that of CT, the difference was statistically significant (P<0.05). The total accuracy rate of CT combined with MRI for rectal cancer and the accuracy rate of lymph node positive diagnosis were higher than those of CT and MRI, and MRI was higher than that of CT, and the difference was statistically significant (P<0.05). The accuracy of MRI in preoperative staging diagnosis and lymph node positive diagnosis of rectal cancer was higher than that of CT, and the difference was statistically significant (P<0.05). The accuracy of CT combined with MRI in preoperative staging diagnosis and lymph node positive diagnosis of rectal cancer was highly consistent with the pathological results, and the consistency was higher than that of CT and MRI, and the difference was statistically significant (P<0.05).Conclusion The combined application of CT and MRI images can improve the accuracy of clinical staging and lymph node positive diagnosis of rectal cancer, and provide reliable basis for formulating treatment plans and judging lymph node metastasis before clinical operation of rectal cancer, which is worthy of clinical application.
