摘要
目的分析CT指数与MR成像对盆腔淋巴结转移的诊断价值。方法方便选择从2016年7月—2018年7月该院收治的宫颈癌初诊患者48例,入院后均接受CT检查、MR成像,最后对比两种诊断方法的价值。结果宫颈癌初诊患者48例中,35例患者经手术病理证实为淋巴结转移,阳性比例为72.92%。CT:淋巴结转移阳性患者的淋巴结表现为中心坏死、可见包膜外侵,以圆形为主,大小与阴性患者相比较(P<0.05)。MRIDWI表明,淋巴结转移阳性患者的ADC值显著低于阴性(t=2.6736,2.5074,5.8704),eADC值显著高于阴性(t=2.5395,3.9244,2.8670,P<0.05)。结论宫颈癌盆腔淋巴结转移会改变CT影像图特征的变化和MR成像参数,具有较高的敏感性和特异性。
Objective To analyze the diagnostic value of CT index and MR imaging in pelvic lymph node metastasis.Methods Convenient select 48 patients with newly diagnosed cervical cancer from July 2016 to July 2018 were enrolled.CT examination and MR imaging were performed after admission.Finally,the value of the two diagnostic methods was compared.Results Of the 48 patients with newly diagnosed cervical cancer,35 patients were confirmed to have lymph node metastasis by surgical pathology.The positive proportion was 72.92%.CT:The lymph nodes in patients with positive lymph node metastasis showed central necrosis and visible capsule invasion,which were mainly round,and the size was compared with negative patients(P<0.05).MRI DWI showed that ADC values in patients with positive lymph node metastasis were significantly lower than negative(t=2.673 6,2.507 4,5.870 4),eADC values were significantly higher than negative(t=2.539 5,3.924 4,2.867 0,P<0.05).Conclusion Cervical cancer pelvic lymph node metastasis can change the characteristics of CT images and MR imaging parameters,and has high sensitivity and specificity.
