目的比较自动乳腺全容积成像(ABVS)与常规超声(US)对乳腺微钙化的诊断价值.方法选择由钼靶检查发现乳腺微钙化的68例患者共71个病灶,均行ABVS和US检查,分别比较两种方法在有无乳腺肿块背景及不同乳腺病理类型中的微钙化检出率,所有病灶均经病理结果证实.结果 71个微钙化灶ABVS和US分别检出65个和55个,ABVS对微钙化的检出率高于US,差异有统计学意义(91.5％对77.5％,x2=5.379,P=0.020).其中有44个微钙化灶位于肿块内,27个未发现肿块.对肿块内微钙化,ABVS和US检出率分别为97.7％和93.2％,两者比较差异无统计学意义(x2=0.262,P=0.609)；ABVS对无肿块背景下微钙化的检出率高于US(81.5％对51.9％,x2=5.333,P=0.021).ABVS和US对浸润性导管癌内微钙化检出率一致(均为100％),但对于导管内癌的微钙化,ABVS的检出率明显高于US(94.1％对58.8％,P=0.039).结论 ABVS能提高超声对微钙化的检出率,特别是无肿块的微钙化.ABVS的冠状面能直观显示微钙化分布范围,可提高超声对导管内癌的鉴别诊断能力.

Objective To compare the values of automated breast volume scanner(ABVS) and conventional ultrasound(US) in the diagnosis of breast microcalcifications.Methods Sixty-eight cases of patients with breast microcalcifications 71 lesions were found by mammography,which were also examined by ABVS and US.The detection rate of microcalcifications under different background which have masses or not by the two methods were compared respectively,and the detection rate in the different pathological types of breast were also compared.All the cases were confirmed with histopathology.Results Sixty-five cases with breast microcalcifications were detected by ABVS and 55 cases detected by US,respectively.The detection rate of ABVS was significantly higher than that of US (91.5％ vs 77.5％,x2 =5.379,P =0.020).Forty-four cases of microcalcifications were found within the masses,but the other 27 cases without mass.The detection rate of microcalcifications within the masses had no siginificant difference between ABVS and US (97.7％ vs 93.2％,x2 =0.262,P =0.609),but ABVS was significantly higher than US (81.5％ vs 51.9％,x2 =5.333,P =0.021) in the detection rate of microcalcifications without the masses.The detection rate of ABVS in microcalcifications for those patients with invasive ductal carcinoma,were found the same as US (both 100％).However,the detection rate of microcalcifications by ABVS was much higher than US (94.1 ％ vs 58.8％,P =0.039) in patients with ductal carcinoma in situ.Conclusions ABVS can improve the detection rate of microcalcifications,especially without mass.The microcalcifications distribution can be observed in the coronal plane of ABVS,which increases the detection rate of ultrasound in the diagnosis of ductal carcinoma in situ.
