A new technique utilizing ultrasound to aid in intrauterine transfusion. | A new technique is described which utilizes ultrasound to diminish fetal exposure to x ray during intrauterine transfusion. In replacing x ray imagery, ultrasound better localizes the exact position of the intrauterine contents, including the vital fetal intraabdominal structures. Using an A mode needle aspiration tran... | 816,818 | [
