hyperenhancement
Definitions
noun
Greater than normal enhancement
However, several enterographic findings are associated with increased disease activity, including wall thickening greater than 4 mm, intramural and mesenteric oedema, mucosal hyperaemia, wall enhancement (and enhancement pattern), transmural ulceration and fistula formation, vascular engorgement and inflammatory mesenteric lymph nodes (often with hyperenhancement).
Greater than background-level brightness.
For example, transmural hyperenhancements ranging from 26 to 50 percent in dysfunctional myocardial segments predicted with a less than 50 percent accuracy a postrevascularization improvement in contractile function.
One would expect the area of hypoenhancement on first-pass imaging to be larger than that of hyperenhancement on delayed contrast-enhanced imaging.
