Radial-SWI in human fetal imaging is presented which includes: (a) determining the minimum number of radial projections necessary for fast measurement of intravascular phase in the blood vessels in human adult and fetus, without loss of accuracy; and (b) exploring the feasibility of fetal venography using radial-SWI. Results of this study illustrate that (a) in both fetal and adult imaging, accurate quantification of intravascular phase from the superior-sagittal-sinus is possible from radial SWI with just 161 projections, and (b) venograms in fetal brain were presented using radial-SWI.
