A Pilot Proof of Concept Study with Paired-Design on the Effectiveness of Metal Related Artifact Reduction of Hip Arthroplasty Implants or Other Metallic Hardware Using Radiofrequency Pulse Polarization Optimization in 3T MRI

Brief description of study

This is a single-center single-arm clinical trial with a paired design which compares the effectiveness of 3T MRI with (modified) and without (standard) radiofrequency pulse polarization optimization in reducing metal-related artifacts in patients with hip arthroplasty implants or other metallic hardware. Twenty participants with symptomatic primary total hip arthroplasty or other metallic hardware will be imaged with both methods. The results of the two methods will be compared in reference to the size of the artifact-degraded regions, visibility of the normal structures and the rate of abnormality detection.
