Ex Vivo MRI is a successful, non-invasive technique for studying disease development and gene function in mutant mouse models. However, there is currently no established method for assessing ex vivo embryos retained in the amniotic sac using MRI. Such a method would be valuable for determining the phenotypes of mutant embryos with abdominal wall defects such as gastroschisis and omphalocele, which are difficult to distinguish between using light microscopy. In this study, we developed a novel methodology to visualise "in amnio" embryos and successfully applied the technique to image a fetus with an omphalocoele defect.
