Ultrafast dynamic contrast enhanced (UF-DCE) MRI is known for its reduced background parenchymal enhancement (BPE), but the evidence is limited. We evaluated BPE, lesion conspicuity and confidence level of UF-DCE MRI compared with those of conventional DCE (C-DCE) MRI. BPE was reduced, and lesion conspicuity and confidence level were improved on UF-DCE MRI compared to C-DCE MRI, indicating another advantage of UF-DCE MRI when applied to younger women and for high-risk screening.
