乳腺癌超声造影表现

目的 探讨不同大小乳腺癌的超声造影表现.方法 84例乳腺癌术前行超声造影检查,其中肿块最大直径>2.0 cm病例共50例,最大直径≤2.0 cm病例共34例;所有病例均应用时间.强度曲线分析软件测定定最参数,并分析时间-强度曲线类型,以及肿块增强模式,分析不同大小肿块超声造影间的差别.结果 在不同大小的乳腺癌病例中,最大直径≤2.0 cm及直径>2.0 cm乳腺癌的基础强度、峰值强度、强化强度、上升斜率、强化强度指数以及曲线类型间差异无统计学意义(P>0.05);增强模式间差异有统计学意义(P<0.01).结论 最大直径≤2.0 cm与直径>2.0 cm乳腺癌超声造影增强模式存在差别.造影诊断乳腺癌时应根据肿瘤的大小区别分析.

Contrast-enhanced ultrasound findings of breast cancer

Objective To study the manifestation of breast cancers of different sizes in contrast-enhanced sonography. Methods Eighty-four patients with breast cancers were examined by contrast-enhanced ultrasound. Among them, the tumor diameter was beyond 2.0 cm in 50 cases, and no greater than 2.0 cm in the rest cases. The time-intensity curve (TIC) on the enhanced images was analyzed quantitatively, and the relations between the type of TIC and the enhancement patterns of the tumors were analyzed. Results The enhanc...
