目的探讨超声引导下细针穿刺细胞学检查对乳腺筛查中临床触诊阴性结节的诊断价值。方法回顾性分析241例超声引导下细针穿刺细胞学检查病例,均为临床触诊阴性而超声显示微小病变。结果超声对微小病变定性的符合率79.3%;超声引导下细针穿刺细胞学检查诊断微小结节的准确性为98.6%。结论乳腺微小结节超声引导下细针穿刺细胞学检查具有定性准确、操作简单、快速、价格低廉,适于在基层医院及乳腺癌筛查中大力推广。
Objective To investigate the diagnostic value of fine needle aspiration biopsy under ultrasound guidance in clinical palpation-negative nodules in breast screening. Methods Retrospective analysis of 241 cases of ultrasound-guided fine needle aspiration cytology cases were negative for clinical palpation and ultrasound showed minimal change. Results The coincidence rate of ultrasonography to minor lesion was 79.3%. The accuracy of ultrasound-guided fine needle aspiration cytology in diagnosing tiny nodules was 98.6%. Conclusion Ultrasound-guided fine needle aspiration cytological examination with qualitative and accurate, simple, fast, low cost, suitable for grass-roots hospitals and breast cancer screening vigorously.
