Tips and tricks of fetal MR imaging

Abstract

The technique of performing fetal MR examinations differs from routine pelvic MR imaging because the fetus is in motion, and image planes must be selected orthogonal to fetal anatomy. The small size of the fetus also increases examination difficulty because thin slices (limited by SNR) are often needed for adequate examination of anatomy and pathology. Knowledge of fetal anatomy and neonatal anatomy/ pathology are needed in the assessment of fetal MR imaging. Knowledge of MR artifacts aids in image interpretation.
