摘要
目的探讨乳腺肿物中收缩期流速峰值(PSV)能否鉴别乳腺的良性与恶性肿物。方法133例经手术或病理证实的乳腺疾病患者,其中,乳腺癌46例,乳腺良性病变87例(包括纤维瘤58例,炎性包块7例及增生性病灶22例),均经二维超声检查,彩色多普勒血流显像(CDFI)测量PSV,对所有病人的超声表现进行回顾性分析,并重点地比较了乳腺癌与乳腺良性病变之间的PSV差异。结果46例乳腺癌的47个病灶中检出血流信号42个,58例纤维瘤的69个病灶中检出血流信号41个,7例炎性包块和22例增生性病灶中均检出血流信号。乳腺癌与乳腺良性病变的PSV比较,未见显著性差异(P>0.05)。结论单独用PSV鉴别乳腺的良恶性肿物是不可靠的,因PSV与多种因素有关。
Objective To explore whether intratumoral peak systolic velocity（PSV） will be able to differentiate the breast benign masses from malignant masses. Methods A hundred and thirty - three patients with surgically or pathologically proved breast diseases which comprised 46 breast carcinomas and 87 breast benign lesions（58 fibromas, 7 inflammatory masses and 22 proliferous lesions）underwent 2D uhraaonographies and measurements of PSV by color Doppler flow imaging（CDFI） . The uhrasonographic findings in all patients were retrospectively analyzed and emphatically compared for PSV between benign and malignant masses. Results The flow signals measured by CDFI were 42 in 47 lesions of 46 carcinomas, 41 in 69 lesions of 58 fibromas, 7 in 7 inflammatory masses, and 22 in 22 proliferous lesions, respectively. There was not significant difference of PSN between benig and malignant masses （ P〉 0.05 ）. Conclusion For the differentiation of benign vs malignant masses, PSV is unreliable because it is related to maniford factors.
