Of these, 80% (92\/115) had T1 hyperintense rectal meconium signal. Average height of the meconium column, measured from the base of the bladder to its most inferior extent, was 9.2\u00a0\u00b1\u00a04.3\u00a0mm in fetuses \u226520\u2010week gestational age and 11.1\u00a0\u00b1\u00a04.4\u00a0mm in fetuses \u226523\u2010week gestational age (n\u00a0=\u00a0110) . None had bowel dilation. One of 115 fetuses had a simple form of anorectal malformation allowing complete repair in the neonatal period, but this fetus had a normal meconium column height on fetal MRI of 22\u00a0mm.
