In a retrospective study (2005-2015) of 12 prenatally diagnosed cases of SBO evaluated by both ultrasonography and MRI, Rubio et al noted that MRI was useful in providing the following information [25] :

  • The distribution of meconium in the small bowel, clarifying the level of obstruction
  • Abnormally diminished meconium in the rectum, suggestive of cystic fibrosis or combined SBO and colonic obstruction (which may be useful in family counseling and postnal care preparation)
  • The evaluation of colon and rectal contents, serving as a fetal enema
