Outline of Final Research Achievements

The purpose of this study was to evaluate whether the vascularity of breast lesions can be assessed using intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) on magnetic resonance (MR) imaging.
The signal intensity (SI) change ratio of breast tumors between each phase of dynamic MR imaging was calculated and correlated with the measured IVIM perfusion parameters.
As a result, significant relationships were found between IVIM and the SI change ratio on dynamic MRI in breast tumor, especially in invasive breast cancers. Non-contrast, multi-b-value DWI might have the potential to assess breast lesions without contrast media.
