目的探讨钼靶X线引导下定位细针穿刺抽吸细胞学检查(fineneedleaspirationcytology,FNAC)或针芯组织学活检术(coreneedlebiopsy,CNB)及其对乳腺微小病变的诊断价值。方法经病理证实的34例35个乳腺微小病变均先行常规钼靶X线摄片,再在钼靶X线引导下定位FNAC或CNB。以手术病理为金标准回顾性分析35个乳腺微小病变的初期钼靶X线诊断率和中期钼靶X线诊断率。随机抽取经手术病理证实的30例30个未行钼靶X线引导下定位FNAC或CNB的乳腺微小病变作为对照。结果钼靶X线引导下35个病变FNAC或CNB均定位成功。2组初步钼靶X线的正确诊断率分别为60%和53.3%(P>0.5),无明显差异。研究组中期钼靶X线的正确诊断率与对照组初步钼靶X线的正确诊断率分别为82.9%和53.3%(P<0.05),有明显差异。结论钼靶X线引导下定位FNAC或CNB操作过程简便、经济、安全,定位准确率高。中期钼靶X线正确诊断率明显提高。
Objective To investigate the diagnostic value of fineneedleaspirationcytology (FNAC) or coreneedlebiopsy (CNB) under the guidance of mammography in the diagnosis of minimal breast lesions. Methods Thirty-four cases of 35 minimal breast lesions confirmed by pathology were performed conventional mammography and then FNAC or CNB was guided by mammography. Surgical pathology as the gold standard retrospective analysis of 35 cases of minimally invasive breast mammography X-ray diagnostic rate and mid-term diagnostic rate of mammography X-ray. Thirty cases of minimally invasive breast lesions with FNAC or CNB under the guidance of mammography were randomly selected from 30 cases confirmed by surgery and pathology. Results All the 35 lesions of FNAC or CNB under the guidance of mammography were successfully located. The correct diagnostic rates of the two groups of mammographic X-ray were 60% and 53.3% (P> 0.5) respectively, with no significant difference. The correct diagnosis rate of mammography X-ray in the study group and that of the control group were 82.9% and 53.3% (P <0.05) respectively, with significant difference. Conclusion Molybdenum target X-ray positioning FNAC or CNB operation is simple, economical, safe, high positioning accuracy. Mid-term mammography X-ray diagnosis of the correct rate was significantly improved.
