Three-dimensional imaging can provide precise anatomical delineation of damaged areas after hepatic injuries, particularly in relation to major vessels. The 3D reconstruction can facilitate decisions regarding intraoperative, re-operative and non-operative management (Goodman et al. 1995). 

Three-dimensional images can be reconstructed from a power US study, with or without administration of contrast media, and visualized as a dne loop. The intratumoral blood-flow of focal liver lesions can thus be visualized and can be useful for the differential diagnosis of hepatic tumors, especially HCC and FNH. In fact, these tumors have distinctly different intratumoral vascular structures (Hirai et al. 1998 Cesarani et al. 1999 Campani et al. 1998). Three-dimensional power Doppler US can effectively depict the associated arteries of HCCs, and there is a good correlation with angiographic study (Liang et al. 2003).
