Normal transverse postmortem ultrasound appearances of the bowel in a 19-week gestational-aged foetus, obtained 8 days after death. The first three images (a–c) demonstrate normal rotation of the bowel. In image (a), the gastric pylorus becomes the first part of the duodenum (solid white arrows) and is seen to cross the midline to the right of the abdomen. In image (b), the second part of the duodenum is shown (white arrows), and finally, in image (c), this becomes the third part of the duodenum as it crosses back to the left side of the abdomen (white arrows). In image (d), normal small and large bowel loops in the lower abdomen are seen and meconium filled, without any significant bowel wall thickening or interloop separation
