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.

Multiplanar volume rendering image (A) of axial source data of a 60-year-old man with pancreatic adenocarcinoma (white arrows) encasing the portal vein and distal superior mesenteric vein (black arrows). Intraluminal filling defect suggestive of a thrombus is seen in the superior mesenteric vein. Note the exquisite display of 3D vascular anatomy of superior mesenteric artery (black arrowheads) in relation with the tumor (B).

Figure 5: Multiplanar volume rendering image (A) of axial source data of a 60-year-old man with pancreatic adenocarcinoma (white arrows) encasing the portal vein and distal superior mesenteric vein (black arrows). Intraluminal filling defect suggestive of a thrombus is seen in the superior mesenteric vein. Note the exquisite display of 3D vascular anatomy of superior mesenteric artery (black arrowheads) in relation with the tumor (B).

Mentions: Encasement of the superior mesenteric artery and/or vein renders the pancreatic tumor surgically unresectable. 3D reconstructions now provide exquisite anatomic detail of vascular structures in vicinity of focal pancreatic lesions (Fig. 5). 3D CT angiography has advantages over catheter angiography in its ability to illustrate anatomic structures outside the vascular lumen and therefore the relationship of the vessels to the tumor can be more clearly illustrated.
