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.

Detailed description

Twenty participants with symptomatic primary total hip arthroplasty 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.Primary Objective: To assess the size of the artifact-degraded regions, defined as regions of the image where underlying anatomic structure are obscured, between modified and standard MRI protocols. Secondary Objectives: (1) To assess the visibility of normal structures between modified and standard MRI protocols. (2) To assess the abnormality detection rate using modified and standard MRI protocols.

Conditions

• Hip Arthropathy

Interventions

Type	Name	Description
DEVICE	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.
