...SA) test, a digital rectal exam, and a transrectal ultrasound exam. Little is known about the sensitivity, or the percentage of people who test positive for a disease among people who have the disease, of these screening tests and the appropriateness of the 4-year screening interval.

... The team did not operate on fetuses in whom fetal ultrasound detected irreversible neurologic damage, nor on fetuses in which the spina bifida defect occurred at a spinal level that would not be expected to cause neurological damage.
