MRI of tissues near metal prostheses have been difficult due to severe susceptibility artifact.
MRI near metal
Hip Prostheses
Clinical Challenge
Technical Approach
Novel metal artifact reduction techniques reduce metal artifact significantly and allow evaluation of periprosthetic fluid collection and pathology of nearby tissues.
Hip Prosthesis Conventional
In conventional T2-weighted image, metal artifact obscures osteolysis (yellow arrows).
Hip Prosthesis MAVRIC
In MAVRIC image, the fluid collection with thick rind (orange arrow) is seen.
