摘　　要：目的探讨多模态MR成像技术诊断宫颈癌临床分析的价值。方法选择102例经病理确诊为宫颈癌的女性患者,术前均接受多模态MR成像技术检查,并对比不同癌症类型、不同病理分化程度、是否有淋巴脉管间隙浸润患者DWI、DTI、DCE-ⅡRⅠ序列各参数差异,以术后病理检测结果为“金标准”,评估多模态MR对宫颈癌分期的诊断价值。结果102例宫颈癌患者中,鳞癌64例,腺癌38例;低分化72例,高分化30例;有淋巴脉管间隙浸润35例;无淋巴脉管间隙浸润67例。鳞癌组ADCDTI、FA、Ve、Kep参数显著低于腺癌组(P<0.05),Ktrans参数显著高于腺癌组(P<0.05),而两组ADCDWI参数差异没有统计学意义(P>0.05);低分化组FA、Ve、Kep参数显著低于高分化组(P<0.05),Ktrans参数显著高于高分化组(P<0.05),两组A D CDTI、A D CDWI参数差异没有统计学意义(P>0.05);有淋巴脉管间隙浸润组Ve、Kep参数显著低于无淋巴脉管间隙浸润组(P<0.05),Ktrans参数显著高于无淋巴脉管间隙浸润组(P<0.05),两组ADCDTI、ADCDWI、FA参数差异没有统计学意义(P>0.05);模态MR成像技术诊断分期结果为Ⅰa期12例,Ⅰb期54例,Ⅱa期42例,Ⅱb期6例,以病理结果为“金标准”,其诊断准确率分别为100.00%,87.04%,85.71%,93.33%,总诊断正确率为87.72%。结论多模态MR成像技术在宫颈癌的诊断与分期方面具有良好的准确度,可以作为宫颈癌患者治疗前评估病变范围的常规检查。Objective To explore the value of clinical analysis of multimodal MR imaging in the diagnosis of cervical cancer.Methods 102 female patients diagnosed with cervical cancer pathologically were selected,and they all received multimodal MR imaging examination before surgery.The differences in DWI,DTI and DCE-IIRI sequence parameters were compared among patients with different types of cancer,different degrees of pathological differentiation and different lymphatic vascular space infiltration.The postoperative pathological detection results were used as the"golden standard"to evaluate the diagnostic value of multimodal MR on cervical cancer staging.Results Among 102 patients with cervical cancer,there were 64 cases of squamous cell carcinoma and 38 cases of adenocarcinoma,and 72 cases of low differentiation and 30 cases of high differentiation,and 35 cases of lymphatic vascular space infiltration and 67 cases without lymphatic vascular space infiltration.The ADCDTI,FA,Ve and Kep in squamous cell carcinoma group were significantly lower than those in adenocarcinoma group(P<0.05)while the Ktrans was significantly higher than that in adenocarcinoma group(P<0.05),and there was no statistically significant difference in ADCDWI between the two groups(P>0.05).The FA,Ve and Kep of low differentiation group were significantly lower than those of high differentiation group(P<0.05)while the Ktrans was significantly higher than that of high differentiation group(P<0.05),but there were no statistical differences in the ADCDTI and ADCDWI between the two groups(P>0.05).The Ve and Kep parameters of lymphatic vascular space infiltration group were significantly lower than those of non-lymphatic vascular space infiltration group(P<0.05)while the Ktrans was significantly higher than that of non-lymphatic vascular space infiltration group(P<0.05),but there was no statistical significance in ADCDTI,ADCDWI and FA(P>0.05).The diagnostic staging results of modal MR imaging were shown as 12 cases in stageⅠa,54 cases in stageⅠb,42 cases i
