  		Fig. 1A —Patient with liver abscess. Lesion is not seen on unenhanced scan (A) but is evident on contrast-enhanced scan (B). Streak artifacts seen on both images were described as result of cardiac motion in this generation of CT scanner. (Reprinted with permission from [1])

  		Fig. 2 —Patient imaged with cholangiographic contrast material. Opacified bile duct is faintly visualized (black arrow) anterior to portal vein. Extensive linear artifacts were attributed to motion of gas in stomach in this generation of CT scanner. (Reprinted with permission from [1])

  		Fig. 3A —Patient with metastatic pancreatic cancer. Multiple lesions are seen on unenhanced study (A) but are not as well seen on contrast-enhanced study (B). Contrast material was given as drip infusion, which results in equilibration of contrast material in portions of lesion, making it less conspicuous. (Reprinted with permission from [1])
