【摘要】：目的探討3.0 T MRI在子宮頸癌術前診斷分期和分化程度評價中的應用價值。方法選擇行手術治療并于術前行MRI檢查的子宮頸癌患者23例,均行擇期宮頸癌切除術。術前均行常規(guī)MRI掃描,掃描橫斷面T2WI、矢狀面T2WI、橫斷面T1WI、冠狀面T2WI,于矢狀面行小FOV體素內(nèi)不相干運動(IVIM)DWI技術掃描,得到腫塊與正常宮頸標準ADC值(ADCstandard值)、純擴散系數(shù)(D值)等參數(shù)。參照婦科腫瘤FIGO 2009分期標準進行術前MRI診斷分期,分別按ADCstandard值0.697×10-3mm2/s、D值0.416×10-3mm2/s為標準進行術前分化程度評價,將MRI診斷分期與分化程度評價結果與術后病理結果比較。結果 MRI術前診斷準確率為100%。術前MRI診斷分期為Ⅰb期7例、Ⅱa15例、Ⅱb期1例,診斷分期正確率為91.3%(21/23)。以ADCstandard值為標準,MRI診斷中低分化13例、高分化9例,中低分化診斷正確率為100%、高分化診斷正確率為90.0%。以D值為標準,MRI診斷中低分化11例、高分化8例,中低分化診斷正確率為84.6%、高分化診斷正確率為80.0%。結論應用3.0T MRI對子宮頸癌進行術前診斷分期具有較高的準確性,IVIM技術參數(shù)中ADCstandard值可用于評價腫瘤分化程度。
[Abstract]:Objective to evaluate the value of 3.0 T MRI in preoperative diagnosis and differentiation of cervical carcinoma. Methods 23 patients with cervical cancer underwent surgical treatment and MRI examination before operation. All patients underwent elective resection of cervical cancer. Conventional MRI scanning was performed before operation, T _ 2WI, T _ 2WI, T _ 1WI, T _ 2WI on the sagittal plane, and IVIMI DWI were performed on the sagittal plane to obtain the parameters such as the standard ADC value of mass and normal cervix, ADCstandard value, pure diffusion coefficient (D value). According to Figo 2009 staging criteria for gynecological tumors, preoperative MRI staging was performed. According to the standard value of 0.697 脳 10 ~ (-3) mm ~ (-2) / s ~ (-1) D value 0.416 脳 10-3mm2/s, the preoperative differentiation degree was evaluated, and the results of diagnosis and differentiation were compared with those of postoperative pathology. Results the diagnostic accuracy of MRI was 100%. Preoperative MRI was performed in 7 cases of stage 鈪，
