Magnetic resonance images of normal fetal bowel

Normal fetal bowel at 24 weeks of gestation (A and B) and 27 weeks of gestation (C and D).
(A) T2w coronal image shows high-signal, fluid-filled loops of bowel throughout the abdomen. Minimal low-signal meconium can be seen in the pelvis.
(B) T1w coronal image better demonstrates high-signal meconium filling the rectosigmoid and descending colon.
(C) T2w coronal image shows low-signal meconium in the rectosigmoid.
(D) T1w coronal image better demonstrates high-signal meconium filling the rectosigmoid.
