目的：探讨核磁共振扩散加权成像（DWI）技术在宫颈癌分期中的价值。方法：通过双盲法将32例宫颈癌患者的 MRI 分期和临床分期分别与病理分期进行比较分析。结果：32例早期宫颈癌临床分期ⅠA 2例、ⅠB 20例、ⅡA 9例，MRI 分期ⅠA 3例、ⅠB 13例、ⅡA 16例，病理分期ⅠA 2例、ⅠB 19例、ⅡA 11例；19例临床分期与手术病理分期结果相吻合，符合率为59．4％；24例 MRI 分期与手术病理分期结果相吻合，符合率为75％；子宫颈的 T2 WI 矢状位和短轴位是发现和观察宫颈癌的主要扫描序列之一；在 DWI 上，宫颈癌组织呈现高信号或稍高信号，ADC 图灰阶成像呈现低信号，正常宫颈组织 ADC 值高于癌组织，差异有统计学意义（P ＜0．05）。结论：宫颈癌 MRI 分期优于临床术前分期，子宫颈的 T2 WI 矢状和短轴位及 DWI 可以作为宫颈癌精确定位、定性和分期的检测方法之一。
目的：探討覈磁共振擴散加權成像（DWI）技術在宮頸癌分期中的價值。方法：通過雙盲法將32例宮頸癌患者的 MRI 分期和臨床分期分彆與病理分期進行比較分析。結果：32例早期宮頸癌臨床分期ⅠA 2例、ⅠB 20例、ⅡA 9例，MRI 分期ⅠA 3例、ⅠB 13例、ⅡA 16例，病理分期ⅠA 2例、ⅠB 19例、ⅡA 11例；19例臨床分期與手術病理分期結果相吻閤，符閤率為59．4％；24例 MRI 分期與手術病理分期結果相吻閤，符閤率為75％；子宮頸的 T2 WI 矢狀位和短軸位是髮現和觀察宮頸癌的主要掃描序列之一；在 DWI 上，宮頸癌組織呈現高信號或稍高信號，ADC 圖灰階成像呈現低信號，正常宮頸組織 ADC 值高于癌組織，差異有統計學意義（P ＜0．05）。結論：宮頸癌 MRI 分期優于臨床術前分期，子宮頸的 T2 WI 矢狀和短軸位及 DWI 可以作為宮頸癌精確定位、定性和分期的檢測方法之一。

Objective:To investigate nuclear magnetic resonance diffusion weighted imaging in diag-nosing cervical cancer staging.Methods:By means of double-blind grouping,respectively comparing and analyzing MRI staging and clinical staging with pathology staging of 32 cervical cancer patients. Results:32 patients with early cervical cancer clinical staging:2 cases of IA,20 cases of IB,9 cases of IIA;MRI staging:3 cases of IA,13 cases of IB,16 cases of IIA;pathology staging:2 cases of IA, 19 cases of IB and 11 cases IIA.Pathological staging results of 19 cases were consistent with surgery pathology results,coincidence rate was 59.4%;MRI staging results of 24 cases were consistent with surgery pathology,coincidence rate was 75%;concerning DWI,cervical cancer tissue showed high signal or higher signal.ADC gray scale showed low signal,the ADC value of normal cervical tissue was higher than that of cancer tissue,differences were statistically significant(P <0.05).Conclusions:Cervical cancer MRI staging is obviously superior to clinical preoperative staging;DWI can serve as a choice for the accurate positioning of cervical cancer,qualitative test and staging.
