High-resolution fetal brain anatomical imaging using a reduced field-of-view with outer volume suppression

Reliable fetal brain anatomical imaging is critical to identify structural brain abnormalities early in utero. Fetal brain imaging with increased spatial resolution may provide more details but is limited by a large acquisition matrix size with a long readout time. Here, we demonstrate high-resolution fetal brain imaging using a reduced field-of-view with outer volume suppression. The performance of outer volume suppression pulse was evaluated in simulations and phantom/in vivo experiments. High-resolution imaging with reduced field-of-view demonstrated improved image quality than conventional imaging without visible blurring or aliasing artifacts.
