A clinical assessment of real time ultrasound.

Clinical experilence with a real time ultrasound machine (ADR 2130, Kretztechnik (U.K.) Ltd.) has demonstrated its versatility and accuracy in early and late pregnancy. Fetal movements and circulation and the site of the placenta can be reliably and convincingly displayed. The assessment of the biparietal diameter is at least as accurate as similar measurements made with a compound sector scan instrument. An important advantage in clinical practice of the ADR 2130 is its portability.
