Blood clots typically appear as primarily hyporeflective amorphous structures presenting with a heterogeneous texture, a combination of hyperreflective speckle and areflective spaces
Unlike keratin plaques blood clots, while having a similar appearance, do not cause distinct bands of shadow but in some cases may produce a diffuse shadow on lower layers
Blood clots beneath the surface have the same presentation to surface clots with the typical heterogeneous texture and predominately hyporeflective appearance
Absence of perfusion and blood flow also define clotted areas
