Objective The aim of the study was to assess the performance and diagnostic value of a dual energy CT approach to reduce metal artefacts in subjects with metallic implants. Methods 31 patients were examined in the area of their metallic implants using a dual energy CT protocol (filtered 140 kVp and...
