Abstract:
Objective To evaluate the application value of time-intensity curve analysis of contrastenhanced ultrasonography (CEUS) in differential diagnosis of malignant and benign breast masses.Methods From January 2015 to September 2015,30 patients with one lesion confirmed by surgical pathology were examined by CEUS.Then time-intensity curve analysis was performed.Results 16 lesions were found in the benign group and 14 lesions were in the malignant group.Five parameters of benign and malignant group were statistically analyzed,including Perfusion slope rate (C),intensity of peak (A),Subsidence slope rate (K),time of peak value (T) and area under the curve (Area).The perfusion slope rate (C) of benign and malignant group is [(0.24 ± 0.41) vs (0.67 ± 0.39)].There was no statistical difference between the two groups in intensity of peak (A),Subsidence slope rate (K),time of peak value (T) and area under the curve (Area),except perfusion slope rate (P＜0.05).Conclusion Time-intensity curve analysis of CEUS has certain effect on differential diagnosis of malignant and benign breast masses.
