When attempting a literature review on contrast-enhanced ultrasound (CEUS) in trauma, very few articles are found. There are a large number of papers dealing with FAST (focused assessment with sonography in trauma) which, in practice, is the definition for detection of free fluid in the abdomen, but there are papers covering assessment of parenchymal damage with nonenhanced ultrasound. This review focuses on direct assessment of parenchymal damage in blunt abdominal trauma, and includes papers on non-enhanced ultrasound to give a historical background to scientific approaches to ultrasound diagnosis of parenchymal injury. A report on our local experience of CEUS in trauma has also been included. © Springer-Verlag 2005.
