Hypoattenuating findings on CT simply tell us that an abnormality is darker then the surrounding normal tissues. We often need more information to know what the abnormality is. Additional testing may be needed to include additional imaging tests. Hypoattenuating is a term used by radiologists, particularly when we are not clear about the diagnosis. OBJECTIVE. CT or MRI is most commonly used for characterizing focal hepatic lesions. However, findings on CT and MRI are occasionally indeterminate. Contrast-enhanced ultrasound (CEUS), with its unique characteristics as a purely intravascular contrast agent and real-time evaluation of enhancement, is a useful next step. The purpose of this article is to review the evidence for performing CEUS 06 Feb 2004 - CTN - Networks rating established. 01 May 2005 - Cryptologic Officer Designators 1610, 1615, 164X AND 744X changed to Information Warfare Officer Designators. 1610 changed to 1810. 01 Mar 2006 - CTO converted to IT rating for E1-E5 and 01 Oct 2006 for E6 and above. 01 Oct 2007 - CTA converted to YN rating.
