乳腺肿块的高频及彩色多普勒超声诊断与病理对照分析

目的探讨高频声像图与彩色多普勒血流(CDFI)对乳腺良恶性肿块的诊断价值,尤其是乳腺增生症的高频声像图所见与病理组织类型的关系,以提高超声对乳腺肿块的诊断符合率。方法对196例乳腺肿块患者的高频声像图及彩色多普勒血流作详细观察记录,将乳腺肿块分为3组,即乳腺增生病81例、乳腺癌70例、乳腺纤维腺瘤45例,与病理学组织类型进行对比研究。结果乳腺增生病,乳腺癌,乳腺纤维腺瘤的高频声像图表现,如肿块的边界、内部回声、肿块数目、钙化、衰减及彩色血流的表现,与病理对照均有不同的特征性表现,但也有一部分有重复交叉的表现。各组肿块的敏感性,特异性,准确率,阴性及阳性预测值,乳腺增生组敏感性89%,特异性96.5%,准确率93%,阴性预测值93%,阳性预测值95%;乳腺癌敏感性89%,特异性94%,准确率92%,阴性预测值96%,阳性预测值89%;乳腺纤维腺瘤敏感性89%,特异性93%,准确率92%,阴性预测值96%,阳性预测值80%。结论乳腺肿块的高频声像图与病理组织学类型对照具有特征性表现,结合CDFI有很大的临床应用价值,可提高诊断乳腺肿块的诊断符合率。

Comparative Study of High Frequency Ultrasonography and CDFI with Pathology in Diagnosis of Breast Tumor

Objective To evaluate the diagnostic role of high frequency ultrasonography(HFU) and CDFI for breast tumor,especially to evaluate the correlation of pathology in hyperplasia of breast.Methods HFU and CDFI findings were compared with pathological study in 196 cases with confirmed breast tumor.The tumor of breast were divided into three groups.They were 81 cases of fibrocystic disease ofbreast,70 cases of breast cancer and 45 cases of fibroadenoma disease of breast.Results The benign and nicious tumor of breast haddifferent and typical represent of HFU,because dates of HUF had correlation with those of pathology,such as tumor boundary,internalecho,mononode and multinode,calcification,attenuation and CDFI.Some patients had crossed represent of HUF and CDFI.Thesensitivity,specificity and accuracy rate were calculated apart from.The sensitivity of fibroscystic disease of breast was 89%,the specificity was 96.5%,the accuracy was 93%,the negative predictive value was 93%,the postive predictive valus was 95%;the sensitivity of cancer of breast was 89%,the specificity was 94%,the accuracy was 92%,the negative predictive value was 96%,the post predictive valus was 89%;the sensitivity of fibroadenoma of breast was 89%,the specifity was 93%,the accuracy was 92%,the negative predictive value was 96%,the postive predictive value was 80%.Conclusion HUF in combination with CDFI are useful in diagnosis of both male and female breast tumor.This study may be helpful in raising the ultrasonic diagnosis rate in breast tumor.
