This article is more in the series of studies done by Federle
and his group to define spiral CT characteristics of various hepatic
neoplasms. The best sign is to get enhancement similar to the
aorta. This was seen in 19-32% of hemangiomas, and only in 0-2%
of malignant tumors. Globular enhancement was seen in more hemangiomas
but was also seen in 4-12%. It should be possible to identify
hypervascular malignancies with a fair degree of specificity.
However the sensitivity for identifying both hemangiomas and malignanices
remains poor. |
