View larger version (99K): [in a new window]   Fig. 1 —Colon segment turned inside out. Three simulated lesions affixed to colon wall. Small 3.5-mm polyp on right side, 7-mm flat lesion in middle, and 7-mm polypoid lesion on left side.

View larger version (136K): [in a new window]   Fig. 2A —Small polypoid lesion less than or equal to 3 mm. Simulated polyp affixed to colon wall.

View larger version (141K): [in a new window]   Fig. 2B —Small polypoid lesion less than or equal to 3 mm. Intraluminal volume rendering.

View larger version (54K): [in a new window]   Fig. 2C —Small polypoid lesion less than or equal to 3 mm. Axial and coronal multiplanar reconstruction. Small lesion (arrow) can be localized in all 2D and 3D views, although conspicuity is highest on 3D display.

View larger version (50K): [in a new window]   Fig. 2D —Small polypoid lesion less than or equal to 3 mm. Axial and coronal multiplanar reconstruction. Small lesion (arrow) can be localized in all 2D and 3D views, although conspicuity is highest on 3D display.

View larger version (132K): [in a new window]   Fig. 3A —Flat lesion 7 mm in width and 2 mm in height. Simulated flat lesion affixed to haustral fold.

View larger version (140K): [in a new window]   Fig. 3B —Flat lesion 7 mm in width and 2 mm in height. Intraluminal volume rendering.

View larger version (49K): [in a new window]   Fig. 3C —Flat lesion 7 mm in width and 2 mm in height. Axial and coronal multiplanar reconstruction. Flat lesion (arrow) is very difficult to appreciate on multiplanar reconstruction and is much more conspicuous on 3D display.

View larger version (38K): [in a new window]   Fig. 3D —Flat lesion 7 mm in width and 2 mm in height. Axial and coronal multiplanar reconstruction. Flat lesion (arrow) is very difficult to appreciate on multiplanar reconstruction and is much more conspicuous on 3D display.

View larger version (124K): [in a new window]   Fig. 4 —Air-distended colon segment placed in dedicated 20 x 30 cm acrylic phantom box. Phantom box had diameter and form of abdominal transverse cross section and was filled with water to simulate abdominal attenuation. To ensure specimen was totally surrounded by water, an acrylic plate was fixed horizontally in upper third of height to keep air-distended colon segment from buoyancy in center of box.
