Outline of Final Research Achievements

This study showed the degree of background parenchymal enhancement (BPE) on preoperative breast MRI affects the diagnosis of tumor extension and surgical planning. Whereas, BPE on breast MRI is associated with menopausal status and background parenchymal findings of US and DWI. Because premenopausal women with heterogeneous background parenchymal echotexture may be predicted to show moderate or marked BPE, scheduling of breast MRI should preferentially be adjusted to the menstrual cycle. One of the challenges for clinical use of preoperative breast MRI is how to transfer prone-MRI information to the operating theatre with a supine surgical position. This study showed that prone-to-supine tumor displacement in the breast differs depending on tumor location and status of breast projection.
