The prototype TWIST-VIBE sequence improves the temporal resolution of breast MRI while preserving spatial resolution. High-temporal resolution TWIST-VIBE was performed during the initial enhancement phase and high-spatial resolution routine DCE MRI in a single session, and whether the additional information of initial enhancement analysis using TWIST-VIBE improved the diagnostic accuracy of breast MRI was evaluated. The combination of BI-RADS and new parameters of initial enhancement (MS and TTE) calculated from TWIST-VIBE has the potential to increase the specificity of breast MRI and may be useful as additional information to determine the need for biopsy.
