Prenatal diagnosis of vasa previa is very important because cesarean delivery dramatically improve the prognosis of the fetus. Although it is important for radiologists to diagnose vasa previa using Magnetic resonance imaging (MRI), there are only a few previous reports about MRI of vasa previa. Thus, we will describe vasa previa with MRI findings of actual cases. The purpose of this exhibit is: 1. To describe the pathophysiology of vasa previa. 2. To discuss the radiological MRI features of vasa previa. There are some variations of vasa previa that cannot be classifiable into typical two types previously reported. 3. To discuss MRI features of the abnormalities of placenta and umbilical cord insertion related to vasa previa. It is important to include entire uterus to evaluate abnormalities of placenta and attachment of umbilical cord.  

Pathophysiology of vasa previa - Types of umbilical cord insertion - Types of vasa previa - Risk factor Review of imaging findings - Classifiable into two types - Unclassifiable type - Comparison between findings of MRI and ultrasonography Summary of the cases Discussion
