Abstract:
Objective:To explore the diagnostic efficacy of contrast-enhanced ultrasound and magnetic resonance imaging (MRI) in the diagnosis of benign and malignant phyllodes tumor of the breast (PTB).Methods：The features of contrast-enhanced ultrasound and MRI in 39 cases of PTB (pathological diagnosis) were retrospectively analyzed,and the diagnostic efficiency of the two methods was compared.Results：There were 27 benign lobar tumors,5 borderline tumors and 7 malignant tumors.Most PTB contrast-enhanced ultrasound showed uneven and high centripetal enhancement with perfusion defect and clear boundary after enhancement,and the enhancement intensity and perfusion defect were significantly different among the three groups (P=0.015,0.009).The MRI features of PTB were mainly T2WI low-signal fissures,uneven enhancement and type II TIC curve type.There were significant differences in low signal separation,enhancement features and ADC values on T2WI (P=0.027,0.001,0.042).The diagnostic efficacy of MRI for PTB was higher than that of contrast-enhanced ultrasound,but the difference was not statistically significant.Conclusion：Ultrasonography has a certain characteristic in PTB,and it has better consistency with MRI in diagnosing PTB.
