良恶性乳腺结节钼靶X线与彩超影像特征分析

Molybdenum target radiographic and color Doppler ultrasonic imaging signs of benign and malignant breast nodules

目的分析乳腺良、恶性结节钼靶X线与彩色多普勒超声CDUS影像特征。方法随机选择经钼靶X线与CDUS检查并经手术病理证实的良、恶性乳腺结节直径≤2.0cm120例影像资料进行回顾性分析。结果120例中,良性结节40例,其病灶在X线片上多呈边缘光滑的圆形或条片状;CDUS可探及包膜回声,多表现为低、中较均质回声;彩色多普勒血流显像CDFI20例,可探及血流信号其中80例血流丰富。恶性结节80例血流丰富。恶性结节80例均为乳腺癌,在钼靶X线片上其病灶多数呈圆形或不规则形,70%边缘毛糙或有分叶,部分病灶内或周围可见细微钙化;CDFI示80例均探及血流信号且有70%病灶血流丰富。结论只要依据乳腺结节在钼靶X线片和CDUS的影像特征,就可以对良性与恶性进行鉴别。

Objective To analyze the molybdenum target rad iographic(MTR)and color Doppler ultrasonic(CDUS )imaging findings of benign and malignant breast nodul es.Methods Imaging data which were selected ran domly from 120patients with benign o r malignant breast nodules(D≤2.0cm)detected by MTR and CDUS and demonstr ated by postoperative pathology were analyzed retrospective-ly.Results Of all patients 40cases were benign n odules in which the most presented ro und or stripepatchy form with smooth borders on MTR.CDUS detected encapsulated ech o which mostly presented low or middl e homogenous echo.Color Doppler flo w imaging(CDFI )re-vealed that the blood flow signals we re found in 50%of benign lesions,whi le the rich blood flow was only found i n 8cases.Other 80cases were malignant nodules i.e.breast c arcinoma.On MTR imaging the most lesions presented round or irregular sh ape with spiculated or lob-ulated margin.Fine calcifications in the inside or surrounding of the le sions were partially found.CDFI shown that the blood flow signals were detected in all patients with breast carcinoma and 70%of lesions present ed the rich blood flow.Conclusion If only based on imaging findings of breast nodules on MTR and/or CDUS,We can differentiate benig n -from malignant breast nodules.[
