摘要
目的 探讨二维超声及彩超对浅表良恶性病变的诊断价值。方法 总结了 93例经手术病理证实的浅表软组织肿物的二维及彩超表现 ,提出了良恶性的鉴别要点。结果 93例病例中 ,包括良性病变 67例 ,恶性病变 2 6例。良性病变表现为边界不清 ,可有包膜 ,回声强或不均 ,前后径小于上下径 ,血流信号显示率 3 1.5 % ,为低速连续或脉动的血流 ,流速小于 15cm /s。恶性病变为边界清晰 ,无包膜 ,回声多较低 ,前后径大于或等于上下径 ,血流信号显示率 85 % ,为脉动的血流 ,流速大于 15cm /s。结论 二维超声在鉴别良恶性病变方面有一定的价值 ,彩超及脉冲多普勒对二维超声有很好的补充作用 ,应当常规用于浅表良恶性病变的诊断中。
Objective To evaluate the diagnostic value of color Doppler flow imaging in differentiating benign superficial lesions from malignant ones. Methods Ninety three patients with palpable masses proved by operation and pathology were reviewed. This paper described sonography and color Doppler flow imaging findings of superficial masses and listed the key points in differentiation malignant from benign masses. Results Among the ninety three cases,67cases were benign and the other 26cases were malignant. The sonographic features of benign one were blurred,ovoid,hyperechoic lesion with a thin capsule. And the flow signal detected rate was lower than malignant ones. Which showed low velocity on Doppler spectrum. However, the malignant one showed just opposite features. Conclusion Color Doppler and pulsed wave Doppler represent a useful adjunct to 2 D sonography and should be routinely included in the evaluation of the superficial lesions. [
