Title: Value of relative CEUS parameters in the differential diagnosis of breast lesions
Abstract: Objective To study the value of parameters and relative parameters of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of breast lesions. Methods A total of 54 patients with breast lesions (31 benign,23 malignant) underwent CEUS. The time-intensity curves of lesions and surrounding tissues were drawn by software of ACQ,and then the parameters and calculation of the relative parameters of CEUS were obtained. Results The time-intensity curves of benign masses closed to those of surrounding tissues,or showed wash-in slowly and wash-out quickly,while of malignant masses showed wash-in quickly and wash-out slowly (P0.05). The lesions'relative arrival time,time to peak and peak intensity were different between benign and malignant lesions (P0.05),but no significant difference was detected in relative base intensity between benign and malignant lesions. Conclusion More attention should be paid to enhancement of surrounding tissues in the study of prameters of CEUS. The relative parameters of CEUS and the shapes of time-intensity curves may help to diagnose breast lesions.
