3 INTRODUCTION Ultrasound imaging (US) is the screening modality of choice for the detection of fetal abnormalities. It has many advantages over other imaging modalities in that images have high anatomical resolution and are performed in " real time " , allowing dynamic assessment of the fetus. In addition, ultrasound is widely available at relatively a low cost compared with other imaging modalities. Its accuracy is however operator dependent. Technical advances in the field of magnetic resonance imaging (MRI) throughout the past 2 decades have influenced its use in fetal imaging. The introduction of fast imaging techniques has amelio
