The Comparison of Diffusion Weighted Imaging with Other Breast Magnetic Resonance Imaging Parameters in diagnosis of Breast Masses

INTRODUCTION: The magnetic resonance imaging parameters such as morphologic features, enhancement kinetics and diffusion restriction can be used for the differential diagnosis of lesions. We aimed to compare the apparent diffusion coefficient values of masses with other magnetic resonance imaging parameters in diagnosis of breast masses.
METHODS: 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 magnetic resonance imaging were enrolled to this study. Total 51 lesions were detected. Routine breast magnetic resonance imaging protocol was performed and images were evaluated. The apparent diffusion coefficient cut-off value was taken as 1,1×10-3mm2 /s according to the literature.
RESULTS: 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 dynamic contrast enhanced of magnetic resonance imaging assessment 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 apparent diffusion coefficient values was 93,1% for benign lesions and 95,5% for malign lesions.
DISCUSSION AND CONCLUSION: We believe that the apparent diffusion coefficient value can provide a higher diagnostic accuracy with the combination of morphological characteristics and contrast kinetics of the lesion and that apparent diffusion coefficient can be used alone because of its high diagnostic accuracy in some cases.
