Takeaways from Pre-Contrast T1 and T2 Breast Magnetic Resonance Imaging in Women with Recently Diagnosed Breast Cancer

Background: dynamic contrast-enhanced magnetic resonance imaging (dce -mri) has been widely used in the management of breast cancer,and its diagnostic value in breast imaging has been demonstrated. there have only been a few reports regarding the usefulness of pre-contrast imaging. knowledge about clinically significant findings of preoperative,pre-contrast t1 and t2 mr images will allow more accurate decisions regarding patient treatment and management. objectives: the aim of this study was to evaluate the clinically significant findings of preoperative,pre-contrast t1 and t2mr images in recently diagnosed breast cancer patients. patients and methods: we analyzed 390 preoperative 3-tmris of recently diagnosed breast cancer patients in whom the diagnosis was confirmed by a core needle biopsy. results:mri findings that were correlated with post-core needle-biopsy changes were observed in 27.9% of the pre-contrast t1 and t2mris (n = 109/390). two of 35 cases that had a subareolar ductal high signal area on the pre-contrast t1 were confirmed by surgery as having nipple-areolar complex involvement. conclusion: a subareolar ductal high signal area on a pre-contrast t1mri must be carefully assessed in combination with dynamic,contrast-enhanced images for proper surgical management. © 2016,tehran university of medical sciences and iranian society of radiology.
