声辐射力弹性成像在引导浅表淋巴结穿刺活检中的应用

目的探讨在浅表淋巴结活穿刺活检中应用辐射力弹性成像引导的临床价值。方法选取2013年1月—2014年4月该院收治的存在恶性肿瘤病史并伴随浅表淋巴结肿大患者116例,随机分为观察组与对照组各58例,对照组样本给予常规引导下的穿刺活检,观察组样本应用声辐射力弹性成像引导下的穿刺活检。结果观察组与对照组患者的取样成功率分别为100.0%与89.6%,诊断准确率分别为94.8%与84.5%,组间比较差异有统计学意义（P〈0.05）。观察组中良性与恶性淋巴结表现患者的SWV均值分别为（1.69±0.34）m/s与（4.13±0.50）m/s,组间比较统计学意义（P〈0.05）。结论采用声辐射力弹性成像引导下开展淋巴穿刺活检,能够更好地指导穿刺活检实施,提高穿刺成功率,并且可以初步判断淋巴结性质。

Application of Acoustic Radiation Force Elastography in Superficial Lymph Node Biopsy Guidance

Objective To investigate the clinical value of radiation force elastography guidance applied to superficial lymph node biopsy. Methods 116 patients with the history of malignant tumor accompanied by superficial lymph node enlargement admitted in our hospital from January 2013 to April 2014 were selected and randomly divided into the observation group and the control group with 58 cases in each. The control group were treated with the conventional guided biopsy, and the observation group were treated with biopsy guided by acoustic radiation force elastography. Results The success rate of the sampling of patients in the observation group and the control group was 100.0% and 89.6%, respectively, and the diagnostic accuracy of the two groups was 94.8% and84.5%, respectively, the differences between the two groups were statistically significant（P〈0.05）. The SWV mean performance of the patients with benign and malignant lymph nodes in the observation group respectively was（1.69 ± 0.34） m/s and（4.13 ± 0.50）m/s with statistically significant difference（P〈0.05）. Conclusion Acoustic radiation force elastography guided lymph node biopsy can better guide the implementation of aspiration biopsy, improve the success rate of puncture, and determine the lymph node properties preliminarily.
