I wanted to add that just because you have one now, doesn't mean you won't need one on the baby later.
Looking at the person him/herself is MUCH different than any prenatal testing.
Your OB's story, and bri's, and mine are all evidence that prenatal testing doesn't necessarily diagnose anything.
Actually, I will maintain that it rarely gives you a prognosis, and only occasionally gives you a diagnosis....far less common that you get a dx than that you have a mistake of the diagnostician or diagnostic equipment.
Even if you DON'T see anything, you may STILL need to see someone after the baby is born.
You know, I might call a good pediatric neurologist and speak to them about it...what the plan would be for after the baby is born given this ultrasound? And given whether or not they see something or not on the fetal MRI? What is the rate of detection failure on the fetal MRI?
Women I know with urinary tract diagnoses talk to pediatric urologists about what they think about the u/s.
In fact, even if you decide to have the fetal MRI, I would have a pediatric neurologist look at the films with you in the room...as a consult.
Don't even get me started about how many different opinions neurologists have....each from the other...
