INTERVENTIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria5
- Patients aged ≥ 18 with unilateral symptomatic (e.g. pain) total hip arthroplasty
- Referred for MRI examination at the discretion of the treating physician
- Provision of signed and dated informed consent form
- No metal hardware in the body including contralateral hip arthroplasty
- No contraindication to MRI: defined as claustrophobia or presence of other MRI-incompatible devices
Exclusion Criteria4
- History of revision hip arthroplasty
- Pregnancy (self-reported, or self-suspected)
- Hip arthroplasty surgery within one year of enrollment
- Clinical indication to administer intravenous contrast material during MRI

Interventions
A technical modification to the standard MRI which only affects radiofrequency pulse polarization attempting to optimize the image quality. All other factors, including pulse sequence parameters, and patient and coil positioning is similar to that of the standard MRI.
