穿刺针直径及声像学特征对超声引导乳腺穿刺活检准确性的临床影响探讨

Clinical Effect of Needle Diameter and Ultrasonic Image Characteristics on the Accuracy of Ultrasound Guided Needle Biopsy

目的分析不同直径穿刺针和声像学特征对超声引导乳腺穿刺活检准确性的影响。方法选择本院收治的100例乳腺穿刺活检后进行外科手术治疗的患者进行分析,并与病理检查结果进行比较,分析其检验准确性。结果穿刺病理活检显示,恶性病灶84例(84.0%),高危病灶9例(9.0%),良性病灶7例(7.0%);与患者的术后病理结果进行比较,16G-CNB、18G-CNB的完全敏感性为98%、绝对敏感性为93%,假阴性率均为1%,穿刺活检符合率为92%,病理符合率为93%。结论 16G、18G空心针在超声引导穿刺活检中对10 mm以上肿块性乳腺疾病的诊断价值明显。

Objective To analyze the influence of different diameter of needle and ultrasonic image characteristics on the accuracy of ultrasound guided needle biopsy.Methods100 cases of breast biopsy in our hospital were analyzed, and compared with the results of pathological examination, analysis of the accuracy of the test.Results 84 cases （84%）, 9 cases （9%）, 7 cases （92%） were high risk lesions, cases （7%） were compared with the pathological results. The complete sensitivity of 18G-CNB, 16G-CNB was 98%, the false negative rate was 93%, false negative rate was 1%, the rate of false negative rate was 93%.Conclusion The diagnostic value of 16G and 18G in the diagnosis of breast diseases with more than 10 mm in ultrasound guided needle biopsy is obvious.
