Fig. 3. 47-year-old man with incidentally detected calcified lung nodule (arrows) on screening chest CT.Chest CT scans were reconstructed via six different reconstruction protocols including FC55/FBP (A), FC55/AIDR-3D (B), FC13-H/FBP (C), FC13-H/AIDR-3D (D), FC13/FBP (E), and FC13/AIDR-3D (F). Calcium volumes varied significantly and calcium was not detected on FC13-H/AIDR-3D (D) and FC13/AIDR-3D (F) by both observers with zero volume score.
