Abstract:
Objective To compare the differences of superb microvascular imaging ( SMI) and color Doppler flow imaging ( CDFI) in the diagnosis of breast tumor microvessels and explore the value of microvascular morphological features in the detection of benign and malignant tumors . Methods SM I and CDFI were performed in 105 patients ( 105 breast tumors) in the breast surgery in our hospital . The morphological characteristics of the microvessels of the breast tumor were observed . Their values in the diagnosis of the benign and malignant of the tumor were compared with the pathological results . Results There were statistically differences in differentiation of microvascular morphologic types of benign and malignant breast tumors between SMI and CDFI ( P ＝ 0 .021 ,0 .042) . The type of diagnosing benign tumors was no blood vessel ,linear and treelike . The type of diagnosing malignant tumors was root hair-like and crab claw-like . The susceptibility ,specificity and accuracy of SMI and CDFI in diagnosing breast tumors were 85 .36% ,93 .75% ,90 .47% and 63 .41% ,90 .47% ,81 .90% . The area of the two ROC curves were 0 .896 and 0 .786 . The results of the Z test show that the diagnostic efficacies of the two methods were statistically significant( Z ＝2 .265 , P ＝0 .037) .Conclusions SMI is more effective than CDFI in detecting low velocity microvessels in breast tumors . Its morphological typing is of clinical significance in the diagnosis of benign and malignant tumors .
