What this Trial Is About
The trial investigates patients with hip arthropathy who have undergone unilateral symptomatic total hip arthroplasty. Researchers are comparing two MRI methods — one standard and one modified with radiofrequency pulse polarization optimization — to see which better reduces metal-related imaging artifacts and improves visibility of normal structures and abnormality detection. This is a single-center, single-arm clinical trial designed to assess these imaging techniques in this specific patient group. Participants will undergo both the standard MRI, which is part of their routine care, and the modified MRI performed for research purposes. The modified MRI uses a technical change affecting only the radiofrequency pulse polarization to optimize image quality while keeping other imaging factors consistent with the standard MRI. All participants will be imaged with both methods during the same visit. During the study visit, researchers will measure the size of artifact-degraded regions where anatomy is obscured, evaluate how clearly normal structures appear, and assess the rate of detecting abnormalities using each MRI method. The entire assessment occurs at the initial visit (Day 0). Participants will be monitored carefully, and all procedures are done under medical supervision. The study is expected to complete by the end of 2027.
