Effect of iterative metal artifact reduction

Case contributed by Bálint Botz
Diagnosis not applicable


Oncological follow-up.

Patient Data

Age: 70 years
Gender: Male

Representative trimmed axial venous phase soft tissue kernel CT stacks shown with and without iterative metal artifact reduction (iMAR) being applied. Note the marked reduction of beam hardeding and streak artifacts caused by the right hip prosthesis. 

Case Discussion

Iterative metal artifact reduction techniques can alleviate streak and beam hardening artifacts caused by dense metallic objects such as prostheses and pacemakers, and can thereby improve the assessment of adjacent soft tissues.
