目的分析乳腺不典型癌的常规超声(US)及自动乳腺全容积扫查(ABVS)的图像特征,探讨ABVS超声对此类病变的诊断价值。方法回顾性分析乳腺常规超声检查BI-RADS分级为3级、4A级及4B级患者84例,共85个乳腺病灶;由独立操作者分别扫查并存留动、静态图,然后由两位高年资医师行双盲读片,比较常规超声、常规超声结合ABVS检查的诊断价值。结果 ABVS与常规超声结合时,诊断的灵敏度、特异度、阳性预测值、阴性预测值均有显著提高,且符合率更高,差异具有统计学意义(92.9%vs 82.4%,χ~2=4.401,P=0.036)。结论 ABVS结合常规超声在乳腺不典型癌的定性诊断上有显著优势。
Objective To analyze the image features of conventional ultrasonography (US) and automatic total breast volume scanning (ABVS) in patients with atypical breast cancer and explore the diagnostic value of ABVS in the diagnosis of such diseases. Methods Retrospective analysis of BI-RADS in breast was performed by routine ultrasonography in 84 patients with grade 3, grade 4A and grade 4B, with a total of 85 breast lesions. The independent operators screened and stored the dynamic and static images respectively, Year-old physician double blind readings, more conventional ultrasound, ultrasound combined with ABVS diagnostic value. Results The sensitivity, specificity, positive predictive value and negative predictive value of ABVS combined with conventional ultrasound were significantly increased and the coincidence rate was higher, the difference was statistically significant (92.9% vs 82.4%, χ ~ 2 = 4.401 , P = 0.036). Conclusion ABVS combined with conventional ultrasound in the diagnosis of breast atypical cancer have a significant advantage.
