NCT04875884

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.

Outcome Measures

Primary Outcomes (1)

  • Assessment of the size of the artifact-degraded regions

    The area of artifact degraded regions (in pixel\^2) in paired images of modified and standard MRIs determined by manual segmentation.

Secondary Outcomes (2)

  • Assessment of the visibility of normal structures

    Visit 1, Day 0

  • Assessment of the abnormality detection rate

Study Arms (1)

MRI group

EXPERIMENTAL

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.

Device: Modified 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.
