Conjoined twins are a rare and complex anomaly of monozygotic twin gestations, in which there is joining of the bodies of two individuals. Prenatal imaging, including fetal MRI, plays a crucial role in prognostication and planning for these twins' families and multi-disciplinary medical teams. The ability of fetal MRI to provide large field-of-view imaging is well-suited to delineate the complicated shared and individual anatomy of these twins. In this review, we describe an approach to the fetal MRI of conjoined twins and its limitations, illustrate the fetal MRI findings of the conjoined twin morphological variants, and discuss common superimposed anomalies. The anatomic features most predictive of these twins' chances for survival and separation are also summarized.
期刊介绍：
Official Journal of the European Society of Pediatric Radiology, the Society for Pediatric Radiology and the Asian and Oceanic Society for Pediatric Radiology
Pediatric Radiology informs its readers of new findings and progress in all areas of pediatric imaging and in related fields. This is achieved by a blend of original papers, complemented by reviews that set out the present state of knowledge in a particular area of the specialty or summarize specific topics in which discussion has led to clear conclusions. Advances in technology, methodology, apparatus and auxiliary equipment are presented, and modifications of standard techniques are described.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
