目的观察子宫内膜癌与非子宫内膜癌的子宫内膜超声图像回声强度的差异,探讨超声图像定量分析对子宫内膜癌的诊断价值。方法选择绝经后不规则阴道流血的患者84例和健康体检正常的绝经期妇女30例(健康组),通过联合应用彩色多普勒超声诊断仪与超声图像定量分析仪检测其子宫内膜回声强度定量指标,并检测子宫内膜厚度。84例患者同时进行病理学检查,根据病理结果分为内膜增生组(48例)、内膜癌组(36例),比较各组间灰阶值及分贝值的差异。结果内膜癌组的子宫内膜厚度、灰阶值及分贝值均高于内膜增生组和健康组(P均<0.01),内膜增生组的子宫内膜厚度、灰阶值及分贝值均高于健康组(P<0.05或<0.01)。结论超声图像定量分析提供了超声影像的数字量化指标,结合子宫内膜厚度,为无创鉴别子宫内膜癌提供了得力手段。
Objective To observe the difference of echo intensities between endometrial carcinoma and non-endometrial carcinoma and to evaluate the diagnostic value of quantitative ultrasound in endometrial carcinoma. Methods 84 cases of irregular vaginal bleeding after menopause and 30 healthy menopausal women (healthy group) were selected. The echogenic intensity of endometrium was detected by color Doppler ultrasonography and ultrasonic image quantitative analyzer Quantitative indicators, and detection of endometrial thickness. Eighty-four patients underwent pathological examination at the same time. According to the pathological findings, they were divided into intimal hyperplasia group (48 cases) and endometrial carcinoma group (36 cases). Differences in grayscale value and decibel value between groups were compared. Results The endometrial thickness, grayscale value and decibel value in endometrial carcinoma group were significantly higher than those in intimal hyperplasia group and healthy group (all P <0.01). In endometrial hyperplasia group, endometrial thickness, grayscale value and decibel value All higher than the healthy group (P <0.05 or <0.01). Conclusion The quantitative analysis of ultrasound images provides the digital quantification index of ultrasound images. Combining the thickness of endometrium, it provides an effective means for non-invasive identification of endometrial cancer.
