Purpose or Case Report: The cardiac system is the part of the fetal anatomy that most frequently suffers from congenital pathology . The fetal heart is routinely studied using first level obstetric ultrasonography. If a fetus is considered to have a cardiac defect, a detailed echocardiographic examination is required. The role of fetal magnetic resonance imaging (MRI) as a tool additional to ultrasound has grown exponentially. Unlike ultrasound imaging, however, MRI is unaffected by maternal and fetal conditions such as obesity and oligohydramnios, which particularly impair sonographic visualization of the fetal heart. In this educational poster, we will provide an overview of fetal cardiac MR imaging methods and their applications in congenital heart disease. This presentation will cover recent technical advances in fetal CMR, the modified anatomic segmental approach to image fetal congenital heart disease, imaging appearances of fetal normal cardiovascular structure and appearances of various structural congenital heart disease on fetal CMR. Multiple imaging examples of fetal congenital heart disease diagnosed by fetal cardiac MR will be presented.
