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 with 16-slice CT scanner. Coronal multiplanar volume rendering (A) and minimum intensity projection (B) images reconstructed from sub-millimeter images (0.625 mm) of a 60-year-old woman show right renal mass. Note the exquisite demonstration of relation of the mass with right renal artery and an accessory renal artery (arrow) (General Medical Systems, Waukesha Wis, U.S.A.).

Figure 19: 3D reconstruction with 16-slice CT scanner. Coronal multiplanar volume rendering (A) and minimum intensity projection (B) images reconstructed from sub-millimeter images (0.625 mm) of a 60-year-old woman show right renal mass. Note the exquisite demonstration of relation of the mass with right renal artery and an accessory renal artery (arrow) (General Medical Systems, Waukesha Wis, U.S.A.).

Mentions: The latest development of MDCT is the 16 slice CT scanner. MDCT can acquire sub-millimeter slices with the promise of equal image quality in the Z-axis (Fig. 19). The major impact of this rapidly evolving technology will be the refinement and optimization of 3D reformation with elimination of common artifacts such as "stair step" artifacts.
