Study Details

Brief 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.

Interventions and Outcome Measures

Arms

experimental: MRI group

Subjects enrolled in this study will undergo both standard and new MRI techniques. The standard MRI is needed for your routine care and as ordered by the referring doctor. The new MRI is performed for research purposes. Participants will be imaged with both methods and the results will be compared.

Interventions

Modified MRI

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.

Primary outcome measure

  • Assessment of the size of the artifact-degraded regions [ Time Frame: Visit 1, Day 0 ]
