Does it use X-ray radiation?: No. It uses ultrasound sound waves rather than ionizing radiation.
When is it commonly performed?: The source suggests that weeks 24–32 of pregnancy are often suitable, although timing depends on clinical needs.
What is 4D ultrasound?: It adds real-time motion to three-dimensional ultrasound images, allowing visualization of fetal movements and features.
