Cystic Artery Localization with a Three-dimensional Angiography Vessel Tracking System Compared with Conventional Two-dimensional Angiography

The 3D vessel rapid tracking system has advantages over conventional 2D hepatic angiography in revealing the cystic artery and its origin site. It is also an important tool to identify the complete distribution of the cystic artery without superselective angiography. Supply to adjacent hepatic parenchyma or tumor by the cystic artery is not insignificant and should be considered during hepatic therapies.
