Abstract :
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 T2 MR images in recently diagnosed
breast cancer patients. Patients and Methods We analyzed 390
preoperative 3-T MRIs 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 T2 MRIs (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 T1 MRI must be carefully assessed in combination with
dynamic, contrast-enhanced images for proper surgical management.
