摘要(Abstract)：
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T2WI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T2WI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。
Objective: To investigate nuclear magnetic resonance diffusion weighted imaging in diagnosing 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.
