ABSTRACT
Three-dimensional (3D) ultrasonography is rapidly gaining popularity as it moves out of the research environment and intothe clinical setting. This modality offers several distinct advantages over conventional ultrasonography. Conventional radiography merges 3D data into two-dimensional (2D) summation images. Radiologists mentally reverse this process by forming 3D impressions of the underlyinganatomy and disease. Tomographic data from ultrasonography, computed tomography (CT) and magnetic resonance (MR) imaging have made this mental reformatting process easier and more accurate.
