Ultrafast magnetic resonance imaging of omphalopagus conjoined twins

Yapışık ikizler oldukça nadir karşılaşılan konjenital malformasyonlardır. Omfalopagus yapışık ikizler bunların arasında ikinci sık karşılaşılan formdur ve yapışıklık genellikle umblikal düzeydedir. Biz burada 24 haftalık gebelikte karşımıza çıkan bu nadir anomalinin hızlı sekans (ultrafast) manyetik rezonans görüntüleme (MRG) bulgularını sunmayı amaçladık. Ultrafast MRG bu tür anomalilerin antenatal karakterizasyonunda ek bilgiler sağlayarak ultrasonografiye yardımcı olabilmektedir.

Omfalopagus yapışık ikizlerde ultrafast manyetik rezonans görüntüleme

Conjoined twins are extremely rare congenital malformations. Omphalopagus twins are the second most common variety of conjoined twins and usually are joined at the umbilicus. Herein, we present ultrafast magnetic resonance imaging (MRI) feature of this rare anomaly at 24 weeks of gestation. Ultrafast MRI can provide additional information that may help ultrasonography for antenatal characterization of such anomalies.
