In brief: Ultrasound, MSAFP.

Prenatal ultrasound should have >90% sensitivity for open neural tube defect detection around 20 weeks.
Earlier (>16 weeks) risk stratification can occur with screening maternal blood for AFP - although that is not diagnostic and has to be followed by ultrasound for confirmation and/or differential diagnosis. Fetal MRI is used as part of evaluation for possible fetal surgery to treat spina bifida.

In brief: Neural tube defects

The primary test is the maternal serum fetal protein.
If that is abnormal, an ultrasound examination and perhaps an amniocentesis.
