Hyperenhancement

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).

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.
