The comparison of diffusion weighted imaging (DWI) with other breast MRI parameters in the diagnosis of breast masses

Abstract

The breast MRI parameters such as morphologic features, enhancement kinetics and diffusion restriction can be used for the differential diagnosis. We aimed to compare the Apperant Diffusion Coefficient (ADC) values of masses with other MRI parameters in diagnosis of breast masses. Between March 2014 and September 2017, 49 female patients in whom a breast mass was diagnosed, determined using ultrasound and mammography and who were further examined with MRI, were enrolled to this study. Total 51 lesions were detected. Routine breast MRI protocol was performed and images were evaluated. The ADC cut-off value was taken as 1,1×10-3mm2 /s according to the literature. Fifty-one lesions were diagnosed with biopsy. Of these lesions, 23 (45.1%) were malignant (20 invasive ductal carcinoma and others) and 28 (54.9%) were benign (20 fibroadenomas and others). The accuracy rate of DCE assessment of MRI was 90,9% for benign lesions in with a type 1 curved lesions, and 81,8% for malign lesions in with a type 3 curved lesions. The accuracy rate of ADC values was 93,1% for benign lesions and 95,5% for malign lesions. We believe that the ADC value can provide a higher diagnostic accuracy with the combination of morphological characteristics and contrast kinetics of the lesion and that ADC can be used alone because of its high diagnostic accuracy in some cases.
