The aim of this study was to demonstrate the feasibility of CINE fetal MRI within a breath-hold with self-gated retrospective binning applied with continuous golden angle radial sampling and iGRASP acceleration. A bSSFP radial acquisition scheme was applied with 0.7x0.7mm² in-plane resolution and a small golden angle of 23.1^o. A total of 3800 radial spokes were acquired within a breath hold of 15s. Cardiac triggering was obtained from the centers of the readouts via Principal Component Analysis. The final images were obtained by using iGRASP. Good quality CINE images from the fetus in the third trimester were acquired.
