KY LEUNG, CSW NGAI, MHY TANG

Three-dimensional/four-dimensional ultrasound (3D/4DUS) is a new technology to provide unique images which cannot be visualised with standard two-dimensional ultrasound. Basic 3D/4D techniques including volume acquisition, multiplanar analysis, surface rendering, volumetry, power Doppler are discussed. 3D/4DUS has found clinical applications in the evaluation of various foetal structures including face, brain, spine, skeleton, extremities and heart. The benefits and disadvantages of 3D/4DUS are reviewed.
