To evaluate the feasibility of ultrafast dynamic contrast‐enhanced (UF‐DCE) magnetic resonance imaging (MRI) with compressed sensing (CS) for the separate identification of breast arteries/veins and perform temporal evaluations of breast arteries and veins with a focus on the association with ipsilateral cancers.

Our Institutional Review Board approved this study with retrospective design. Twenty‐five female patients who underwent UF‐DCE MRI at 3T were included. UF‐DCE MRI consisting of 20 continuous frames was acquired using a prototype 3D gradient‐echo volumetric interpolated breath‐hold sequence including a CS reconstruction: temporal resolution, 3.65 sec/frame; spatial resolution, 0.9 × 1.3 × 2.5 mm. Two readers analyzed 19 maximum intensity projection images reconstructed from subtracted images, separately identified breast arteries/veins and the earliest …
