Three-dimensional ultrasound study of fetal craniofacial anatomy
Ultrasound has placed itself in a strong position as an imaging technique in day to day obstetric
care. This is the result of many advantages over techniques such as MRI (magnetic resonance
imaging) and CT (computer tomography), in particular the flexibility of the technique, the
moderate costs, the possibility of real-time imaging and the use of non-ionizing radiation.1
In the Netherlands, ultrasound is used on a regular basis in all obstetric units and by most
regional midwifery services. During the last decades the image quality has strongly improved,
partially due to the development of new ultrasound techniques.
When using the technique of conventional two-dimensional ultrasound (2DUS) the ultrasonographer
tries to form a mental three-dimensional (3D) picture of the fetal anatomy from
two-dimensional (2D) planes. This process tends to become more difficult and time-consuming
when the structure itself and the circumstances are more complicated, thus enhancing the
risk of misinterpretation.2 This shortcoming of conventional ultrasound techniques opened
up the way for three-dimensional ultrasound (3DUS) in fetal imaging at the beginning of the
90s
Three-dimensional sonographic measurement of normal fetal brain volume during the second half of pregnancy
Objectives: This study was undertaken to develop a three-dimensional (3D) ultrasound method of measuring fetal brain volume. Study design: Serial 3D sonographic measurements of fetal brain volume were made in 68 normal singleton pregnancies a
