With the injection of contrast, active bleeding is visible as a bright white “blush” or amorphous collection on arterial phase imaging within a hypodense injured solid organ indicates active bleeding. This must be distinguished from normal enhancement of vessels within solid organs, such as portal and hepatic vessels within the liver. On delayed imaging the area of active extravasation remains high in attenuation and increases in size (Figure 4.), a result of ongoing bleeding from the injured vessel after the initial phases of scanning. .
