Prenatal imaging, including fetal MRI, plays a crucial role in prognostication and planning for these twins\u2019 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\u2019 chances for survival and separation are also summarized.<\/jats:p>","DOI":"10.1007\/s00247-025-06323-1","type":"journal-article","created":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T06:43:15Z","timestamp":1755240195000},"page":"1757-1775","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Fetal MRI findings in conjoined twin pregnancies"],"prefix":"10.1007","volume":"56","author":[{"given":"Julie E.","family":"Walcutt","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beth M.","family":"Kline-Fath","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rama S.","family":"Ayyala","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Foong-Yen","family":"Lim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Usha D.","family":"Nagaraj","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,8,15]]},"reference":[{"key":"6323_CR1","doi-asserted-by":"publisher","first-page":"385","DOI":"10.1002\/ca.22839","volume":"30","author":"A Mian","year":"2017","unstructured":"Mian A, Gabra NI, Sharma T, Topale N, Gielecki J, Tubbs RS, Loukas M (2017) Conjoined twins: from conception to separation, a review.
