How great would it be to be able to tell in advance whether a particular birth would go smoothly or need intervention!
A French team of physicians reported this week at the annual meeting of the Radiological Society of North America that it has developed a new computer model that uses magnetic resonance imaging to predict whether a birth will go smoothly or have problems.
Olivier Ami MD told a session of the RSNA meeting in Chicago that his team applied the new software, called Predibirth, to 24 MR images of pregnant women, and created a three-dimensional model of the woman's pelvis and the fetus. Using these images, Predibirth calculated the likelihood that the babies could find their way out of their mothers' bodies without assistance.
Of the 24 women studied, 13 delivered normally. Predibirth had predicted normal births for all of these women. Predibirth had tagged three women who opted for elective Cesarean sections as being at risk for dystocia.
Of five women who had emergency C-sections, Predibirth had predicted three might have problems — all three involved instructed labor. However, Predibirth had given thumbs up to two of the mothers, whose problems involved heart arrhythmia.
Predibirth had declared "mildly favorable" three additional moms who wound up resorting to vacuum extraction during birth.
Not perfect, but not bad.
"With this virtual childbirth software, the majority of C-sections could be planned rather than emergency, and difficult instrumental extractions might disappear in the near future," Dr. Ami told his audience in Chicago.
Dr. Ami M.D. is an obstetrician in the radiology department at Antoine Béclère Hospital, Université Paris Sud, France.
