The extreme undersampling factors used in radial magnetic resonance fingerprinting (MRF) of the prostate lead to strong streak artefacts from the femoral arteries and veins. However, it turns out that only a subset of receiver channels is responsible for these streaks. In this work we automatically detected and removed these from the reconstruction pipeline. The method was applied to MRF acquired with various acceleration factors in seven asymptomatic volunteers, significantly reducing visible streaks in reference tissues surrounding the prostate without impairing the prostate T1 and T2 values in the MRF maps.
