MRI near metal
Hip Prostheses

Clinical Challenge

MRI of tissues near metal prostheses have been difficult due to severe susceptibility artifact.

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.
