Diagnosis of Breast Lesions by Vibrant Enhanced MRI

Objective:To investigate the value of Vibrant enhanced MRI in diagnosis of breast lesions.Methods:Thirty-three patients with breast lesions,surgically and pathologically proved,were enrolled in our series.All lesions were evaluated with plain and vibrant enhanced MRI.The morphological manifestations of enhancing patterns and the types of time-signal intensity curve of the lesions were analyzed.Results:There were 20 malignant and 25 benign lesions in our collection of 33 patients.A great number of the benign lesions showed rotund and smooth margins,while the malignant lesions revealed irregular,speculated and lobular ones.The enhancement patterns of malignant and benign lesions were different.Significant diffe-rences in the types of time-signal intensity curve between benign and malignant lesions(χ2=26.1,P0.001)were shown.Conclusion:Enhanced MRI of breast offered conspicuous signs and more information in morphological features of the lesions and the characteristics of time-signal intensity curves which reflected the hemodynamics of benign and malinant lesions.In MR diagnosis of breast lesions,the study on the morphological features of the lesions in combination with the characteristics of time-signal intensity curves was of great clinical importance.
