Abstract:
Objective To investigate the diagnostic value of superb microvascular imaging ( SM I ) , advanced dynamic flow ( ADF ) and color Doppler flow imaging ( CDFI) in breast microcarcinoma ,and to compare the correlation coefficients between these three indicators and postoperative pathological tumor microvascular density ( M VD ) . Methods A total of 85 patients ( 87 lesions ) with BI‐RADS 4 and the maximum diameter≤1 cm were selected ,of which ,46 lesions were benign ( benign group) and 41 lesions were malignant( malignant group) . All the patients and the corresponding lesions were examined by SM I , ADF and CDFI . Blood flow grading was performed on the images using Adler grade of blood flow ,and the difference of blood flow among the 3 methods was compared . T he expression level of M VD in pathological tumor tissues was detected and analyzed for its correlation with Adler classification by three detection techniques . Results T he areas under the ROC curve( AUR) of CDFI ,ADF and SM I were 0 .694 ,0 .705 and 0 .776 respectively based on the gold standard with pathological diagnosis . T he sensitivity ,specificity , positive predictive value ,negative predictive value ,and accuracy of CDFI were 78 .0% ,54 .3% ,60 .4% , 73 .5% ,and 65 .5% , respectively ; those of ADF were 75 .6% , 60 .9% , 63 .3% , 73 .7% and 67 .8% , respectively ; and those of SM I were 78 .0% ,69 .6% ,69 .6% ,78 .0% and 73 .6% ,respectively . T he Adler grades of CDFI , ADF and SM I were positively correlated with M VD ( P ＜ 0 .05 ) , w hich the highest correlation coefficient between SM I and M VD ( r ＝0 .430 , P ＜0 .001 ) . Conclusions SM I is superior to ADF and CDFI in detecting the abundance of breast microcarcinoma , and has the highest correlation coefficient among those 3 detection techniques with tumor pathological M VD ,which indicates that SM I may be used for differential diagnosis of breast microcarcinoma and indirectly evaluate the prognosis of patients .
