DCE-MRI联合DWI对不同病理类型子宫肌瘤的诊断价值

The Diagnostic Value of DCE-MRI Combined with DWI in Different Pathological Types of Uterine Fibroids

  • 摘要: 目的:探讨磁共振动态对比增强成像(DCE-MRI)联合磁共振扩散加权成像(DWI)检查对不同病理类型子宫肌瘤的诊断价值。方法:回顾性分析50例子宫肌瘤患者的MRI影像资料,包括DCE-MRI和DWI检查。当肌瘤多发时选取体积最大者进行分析。所有患者均有术后病理证实,并根据病理类型分为:普通型27例、富细胞型6例、退变型17例,对单项及联合MRI检查在不同病理分型中的诊断效能进行评估。结果:MRI检查能准确对肌瘤进行定位,检出浆膜下肌瘤15例,肌壁间肌瘤27例,黏膜下肌瘤8例。在DWI上,富细胞型肌瘤呈高信号,ADC值较普通型及退变型低(P<0.05),差异有统计学意义;在DCE-MRI上,富细胞型肌瘤的定量参数Ktrans、Kep高于普通型与退变型,差异有统计学意义(P<0.05);两者联合检查诊断灵敏度较单项检查更高,差异有统计学意义(P<0.05)。结论:DCE-MRI联合DWI对于不同病理类型子宫肌瘤的鉴别与诊断有重要的临床价值。

     

    Abstract: Objective: The aim of this study was to investigate the diagnostic utility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) combined with diffusion-weighted imaging (DWI) in differentiating various pathological types of uterine fibroids. Method: Fifty MRI scans were retrospectively acquired in patients with uterine fibroids, including both DCE-MRI and DWI scans. In cases of multiple fibroids, the one with the largest volume was selected for analysis. Fibroids were confirmed in all patients using postoperative pathology, and were categorized into common (27 cases), rich-cell (6 cases), and degenerative (17 cases) types. The diagnostic performance of DCE-MRI, DWI, and their combination across different pathological types was assessed. Results: MRI accurately localized the fibroids, identifying 15 subserosal, 27 intramural, and 8 submucosal fibroids. In DWI, rich-cell-type fibroids exhibited significantly higher signal intensity and lower Apparent diffusion coefficient(ADC )values compared to normal and degenerative types (P < 0.05); In DCE-MRI, the quantitative parameters Ktrans and Kep were significantly higher in rich-cell-type fibroids than the normal and degenerative types (P<0.05). The combined examination demonstrated significantly higher diagnostic sensitivity compared to individual DCE-MRI or DWI (P<0.05). Conclusion: The application of DCE-MRI combined with DWI showed significant clinical value in the differential diagnosis of uterine fibroids of various pathological types.
