目的：分析颈部良恶性淋巴结的超声造影(CEUS)特点。方法：对37例颈部淋巴结肿大行CEUS检查及病理活检，按病理结果分为良性和恶性两组，总结分析两组超声造影特点。结果：与良性组相比，恶性组的超声造影增强模式及有无充盈缺损的差异有统计学意义( P0.05)。结论：CEUS对颈部淋巴结进行良恶性鉴别，能够在增强模式方面提供有用的信息，提高诊断的敏感度。“,”Objective: To analysis the characteristics of contrast-enhance ultrasound imaging in cervical benign and malignant lymph nodes. Methods: Thirty-seven patients who were planed to contrast ultrasound and biopsy because of lymphadenectasis were devided into benign lymph nodes group and malignant lymph nodes group by biopsy, summarize and analyze the different characteristics of them. Results: Compared with benign cervical lymph nodes, there were significant differences in enhanced modes and presence of fil ing defect of malignant cervical lymph nodes by contrast-enhance ultrasound imaging. Conclusions: CEUS could differentiate diagnosis cervical benign and malignant lymph nodes, and provided useful informations in enhanced modes to improve its diagnostic sensitivity.
