| 目的 应用三维能量多普勒超声对子宫内膜癌组、良性病变组、正常对照组及绝经期组进行对比研究,以提高子宫内膜癌的早期诊断及检出。 方法 使用三维能量多普勒超声观察199例阴道流血患者(依据病理检查结果分为良性病变组、内膜癌组及正常组)和30例绝经组的子宫内膜,采集并对比血流动力学参数：收缩期峰值流速(Vmax)、阻力指数(RI)、搏动指数(PI)、血管形成指数(VI)、血流指数(F I)、血管形成—血流指数(VFI),评价其在子宫内膜癌诊断中的意义。结果 子宫内膜癌组、良性病变组和正常对照组子宫内膜内血流的收缩期峰值流速的均值间差别无显著性意义(P>0.05)；子宫内膜癌组与良性病变组及正常对照组RI 与 PI的均值差别均具有显著性意义(P均＜0.01)；子宫内膜癌组的血管参数VI、FI、VFI值均高于良性病变组、正常对照组及正常绝经组相关参数值,差异均具有显著性(P均＜0.01)；良性病变组的血流参数VI、FI、VFI值均高于正常对照组及正常绝经组相关参数值,差异均具有显著性(P均＜0.05)；正常对照组的血流参数VI、FI、VFI值均高于正常绝经组相关参数值,差异均具有显著性(P均＜0.05)。结论 三维能量多普勒超声能为子宫内膜癌组与内膜良性病变及正常组的鉴别诊断提供有价值的信息,可进一步提高子宫内膜癌的诊断准确性,对早期诊断子宫内膜癌有重要意义。 |

| Abstract: |
| Objectives Three-dimensional energy Doppler ultrasonography was used to detect of endometrial carcinoma by comparing the early diagnosis and endometrial cancer group, benign disease group, normal control group and menopausal group. Methods Three-dimensional energy Doppler ultrasonography was used to observe the endometrium of 199 patients with vaginal bleeding (divided into benign lesion group, endometrial carcinoma group and normal group) and 30 cases of menopausal group by collecting and comparing hemodynamic parameters. The hemodynamics parameters including: systolic peak velocity (Vmax), resistance index (RI), pulsatility index (PI), angiogenesis index (VI), blood flow index (FI), angiogenesis-blood flow index (VFI) ,to evaluate the significance of parameters in the diagnosis of endometrial cancer. Results There was no significant difference in the systolic peak flow velocity between endometrial carcinoma group, benign lesion group and normal control group (P> 0.05); There were significant differences in the mean values of RI and PI between endometrial carcinoma group and benign lesion group and normal control group (P <0.01);The vascular parameters VI, FI and VFI of endometrial carcinoma group were higher than those of benign lesion group, normal control group and normal menopause group (P <0.01);The parameters of vascular parameters VI, FI and VFI in benign lesion group were significantly higher than those in normal control group and normal menopause group (P <0.05);The blood flow parameters VI, FI and VFI of the normal control group were higher than those of the normal menopause group (P <0.05).Conclusion Three-dimensional energy Doppler ultrasound can provide valuable information for the differential diagnosis of endometrial carcinoma and benign lesions and normal groups, which can further improve the diagnostic accuracy of endometrial carcinoma and early diagnosis of endometrial cancer significance. |
