Breast Dynamic Contrast-Enhanced (DCE) examinations are
usually performed with fat suppression, providing
qualitative enhancement curves. In contrast,
pharmacokinetic modelling often uses spoiled
gradient-echo images and a proton density weighted image
as a reference to calculate T1 values. It would be
desirable to calculate T1 values from fat suppressed
clinical DCE examinations to quantify contrast-agent
uptake in longitudinal studies and to assess parenchymal
enhancement. In this work we introduce a reference image
of low flip angle and a calibration process, and
evaluate the accuracy of T1 values thus obtained. T1
measurements are viable in fat suppressed breast DCE.
