Besides gender, what else does a diagnostic ultrasound show?

Q: My husband and I don't want to know our child's gender; is there any other reason to schedule a diagnostic ultrasound?

A: The American College of Obstetricians and Gynecologists recommends that all pregnant women be offered a diagnostic, or level-3, ultrasound, and I heartily agree. This is the gold standard not only for confirming the age of your fetus, but also for evaluating its health--whether or not you want to know its gender. The optimum timing for a diagnostic ultrasound is 20 weeks, at which time the size and anatomy of the fetus can be well-visualized. Happily, most babies are perfect, but in the unusual case that a medical condition is discovered, being forewarned allows us to have the necessary specialists in place at the time of delivery.
