Abstract：Objective:To study the application value of morphological characteristics of breast mass on magnetic resonance imaging in benign and malignant differentiation.Methods:Clinical data were collected from 451 patients who underwent breast MRI in the hospital from August 2020 to August 2021.The MRI data of 91 patients with pathologically confirmed breast mass le-sions were retrospectively analyzed,including 40 benign mass lesions and 51 malignant mass lesions.Morphological features such as maximum diameter,shape and margins of benign and malignant breast masses were compared,and the diagnostic efficacy of morphological features of the masses was analyzed.Results:The maximum diameter of the masses in the benign and malignant groups were(15.15±6.21)mm and(22.76±11.57)mm,respectively,with statistically significant differences(t=3.758,P＜0.001).The shape of the masses in the benign group was predominantly ovoid(62.5%)and the shape of the masses in the malignant group was predominantly irregular(56.9%),with statistically significant differences(χ2=30.018,P＜0.001).The margin of the benign group was predominantly clear and shiny(80.0%),while the margin of the malignant group was predominantly irregular(51.0%)and burred(45.1%),with a statistically significant difference(χ2=58.525,P＜0.001).The sensitivity of the maximum diameter,shape,and margin of the mass for the diagnosis of benign and malignant breast masses was 77%,57%,and 96%,the specificity was 63%,85%,and 80%,and the accuracy was 70%,69%,and 89%.Conclusion:The morphological features of breast MRI masses have some application in the differential diagnosis of benign and malignant masses,and the sensitivity,specificity and accuracy of mass margins are high.
