Optimized MRI for Patients with Hip Replacements

This study is testing a new way to perform an MRI (magnetic resonance imaging) scan for people who have had a total hip replacement. The goal is to see if a "Modified MRI" technique, which changes how radiofrequency pulses are used, can create clearer images by reducing blurry areas caused by the metal implant. Researchers will compare these modified MRI scans to standard MRI scans in people aged 18 to 99 who have a painful hip replacement and no other metal in their body. The main goal is to measure how much the blurry areas are reduced. This study is currently unclear on its recruitment status.

Study design
This is a single-center study with 20 participants. It compares two MRI methods (modified and standard) in the same individuals.
What's involved
You would have two different MRI scans performed during one visit.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint is measured at Visit 1, Day 0, suggesting no long-term follow-up.
