Primary: To increase awareness of a diagnostic pitfall in order to avoid over diagnosis of liver disease while utilizing low dose techniques. Secondary: Review of the classic CT imaging characteristics of cirrhosis.

A. Classic imaging characteristics of cirrhosis on CT. B. Advantages and disadvantages of dose reduction techniques. C. Pseudocirrhosis: A description of new imaging entity seen during attempts to markedly reduce radiation exposure in CTPA and non-contrast vascular chest CT studies. - Description of findings seen on CT with sample cases. - Follow up imaging cases with separate modality (ultrasound or other) showing finding of cirrhosis to be false and an artifact of dose reduction techniques. D. Increase awareness of this particular diagnostic pitfall to avoid over diagnosis and to promote continued exploration and understanding of both the limits and advantages of dose reduction techniques.
