Around the periphery of the cavity, thousands of iron atoms are scavenged by macrophages and glial cells into aggregates know as ferritin and hemosiderin.

Each Fe center has one free coordination site to which oxygen and other small molecules may transiently bind.

The center of chronic hematomas usually have high water content, rendering them bright, not dark, on T2-weighted images.

Short tau inversion recovery STIR STIR is based on a T2 image, but the image is manipulated in a way that results in fat and any other materials with similar signals being nullified.

This is illustrated the image right where signal in the cardiac chambers is well-suppressed but that in the descending aorta red arrow is not.
