All ultrasound examinations showed fetal intestinal dilation and fetal MRI diagnosis suspected midgut volvulus in 32 cases (32\/156), of which 18 cases (18\/32) that underwent surgical treatment in the neonatal period were confirmed to have midgut volvulus. MRI signs in the 18 fetuses with midgut volvulus were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>During MRI examination, all 18 fetuses showed gastric and\/or intestinal dilatation, most of which showed different degrees of obstruction in T1-weighted images (WIs) and T2WIs, showing the \u201cblack and white sign\u201d (14\/18), \u201cwhirlpool sign\u201d (10\/18), and \u201ccoffee bean sign\u201d (6\/18). High signal intensity changes in diffusion-weighted imaging sequences were observed in intestinal tubes with ischemia and infarction. Direct signs of vascular torsion were observed in some cases (8\/18). MRI signs indicated fetal midgut volvulus with hydramnios (16\/18), meconium pseudocyst (7\/18), meconium peritonitis (4\/18), testicular hydrocele (3\/18), and secondary pulmonary dysplasia (6\/18). Operations confirmed the diagnosis of segmental midgut volvulus in 15 cases, complete midgut volvulus in 3 cases, and combined with intestinal atresia in 8 cases.<\/jats:p>\n
