The presence of orthopaedic hardware creates significant distortion artifacts in MR images. This study evaluated the accuracy of artifact reduction between standard of care 2D fast-spin-echo (FSE) images and corresponding MAVRIC images as compared to a gold standard. Metal samples produced significant distortions in 2D-FSE images, which were eliminated in MAVRIC images. The average difference between the known phantom data points and MAVRIC data points was less than 2 pixels for scans of all materials. MAVRIC scans are effective in reducing image distortion, when compared to known dimensions.
