Time-Resolved 3D Fetal Imaging: Preliminary Results

Jing Liu¹, Orit Glenn¹, Duan Xu¹

Time-resolved whole brain fetal imaging was achieved by using a multi-echo radial sequence during a continuous scan of about 3 minutes, with the mother breathing freely. Preliminary results demonstrated that the images of fetus obtained in vivo could be retrospectively selected with the time-resolved 3D images. Gating signals were derived from the image data and can be applied for motion compensation. Image registration of the time-resolved 3D images can further improve the image quality and data acquisition efficiency.
