Abstract:
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.
