Bottom Line: This pictorial essay describes the improvements in 3D reconstruction and technical aspects of 3D reconstruction and rendering techniques available for abdominal imaging.Clinical applications of 3D imaging in abdomen including liver, pancreaticobiliary system, urinary and gastrointestinal tracts and imaging before and after transplantation are discussed.In addition, this article briefly discusses the disadvantages of thin-slice acquisitions including increasing numbers of transverse images, which must be reviewed by the radiologist.

ABSTRACT
Enhanced z-axis coverage with thin overlapping slices in breath-hold acquisitions with multidetector CT (MDCT) has considerably enhanced the quality of multiplanar 3D reconstruction. This pictorial essay describes the improvements in 3D reconstruction and technical aspects of 3D reconstruction and rendering techniques available for abdominal imaging. Clinical applications of 3D imaging in abdomen including liver, pancreaticobiliary system, urinary and gastrointestinal tracts and imaging before and after transplantation are discussed. In addition, this article briefly discusses the disadvantages of thin-slice acquisitions including increasing numbers of transverse images, which must be reviewed by the radiologist.

3D reconstruction of axial source data of 42-year-old man, status post-liver transplant. Doppler examination did not definitively demonstrate hepatic arterial flow. Multiplanar reconstruction image shows patent donor (white arrowhead) and recipient hepatic artery (black arrowhead) and demonstrates the position of transjugular intrahepatic portrsystemic shunt (arrow).

Figure 3: 3D reconstruction of axial source data of 42-year-old man, status post-liver transplant. Doppler examination did not definitively demonstrate hepatic arterial flow. Multiplanar reconstruction image shows patent donor (white arrowhead) and recipient hepatic artery (black arrowhead) and demonstrates the position of transjugular intrahepatic portrsystemic shunt (arrow).

Mentions: All organ recipients with end-stage liver failure are evaluated prior to liver transplantation with dual phase MDCT of the liver. The acquired image data in the arterial and portal venous phases allows state-of-the-art CT angiography, portal and hepatic venography to be performed (3, 4). Protocols for 3D CT angiography should not include oral contrast administration. 3D reformats can depict pre-operative and post-transplant vascular anatomy and anomalies particularly of the hepatic artery, portal and hepatic veins (Figs. 1-3) (3, 4).
