| 目的 探讨乳腺癌术后引流区域淋巴结反应性增生的超声造影特点。方法 回顾性分析30例患者共35个淋巴结的常规超声及超声造影声像图（灰阶图，彩色多普勒血流图，超声造影图），超声造影使用声诺维混悬液2.4ml于肘静脉团注，获取动态图像应用时间-强度曲线分析得到相关参数。结果 乳腺癌术后引流区域淋巴结体积较小，平均大小在1.25±0.68cm，常规超声结合超声造影对淋巴结反应性增生的诊断准确率较单独使用常规超声高（85.7%，62.9%，P＜0.05）。28例表现为从淋巴门开始的显著增强，4例为从周边开始向中央的增强，3例为中央及周边同步整体增强，三者间差别有统计学意义(P＜0.01)。24例为均匀性增强，11例为不均匀性增强，二者差别有统计学意义(P＜0.01)。超声造影始增时间及峰值时间均值为16.4±6.3s，23.4±7.9s。结论 超声造影能提高乳腺癌术后引流区域淋巴结反应性增生的诊断准确率，造影主要表现为离心型均匀性增强。 |

| Abstract: |
| Object To investigate the characteristics of reactive lymphoid hyperplasia after modified radical mastectomy with contrast-enhanced ultrasound(CEUS). Methods Thirty-five lymph nodes from 30 patients were studied both by conventional ultrasonographic techniques and by CEUS（gray scale,color Doppler,CEUS）. CEUS was performed with 2.4 ml intravenous bolus of contrast agent SonoVue and the results were registered with a software(Time-intensity curve).Atm,TtoPK,Grad were calculated and analysed.Results The average size of 35 lymph nodes were 1.25±0.68cm.Compare US and CEUS to conventional US,the accuracy were 85.7% vs 62.9%. The ultrasonorams of 28 cases were central enhancement,4 cases were peripheral enhancement,3 cases were both central and peripheral enhancement.The differences were statistically significant (P＜0.01). Time to arrival and time to peak were (16.4±6.3)s vs (23.4±7.9)s. Conclusions CEUS was the most accurate to characterize regional reactive lymph nodes after radical mastectomy. Enhancement pattern was centrifugal and homogeneous. |
