Clinical Trial of Chest Tomosynthesis

   
 
Figure 2. Images of a suspicious lesion. (a) A nodule-like opacity was noted in the PA radiograph.
 
   
 
(b) The tomosynthesis images revealed it to be a rib osteophyte and ruled out a pulmonary nodule. This finding demonstrates that tomosynthesis may not only improve sensitivity but may also potentially improve specificity by ruling out nodule mimics.
