Overview
Brief Summary
The goal of this observational study is to develop whole-joint quantitative MRI techniques that aid in the detection and tracking of osteoarthritis disease progression at 3T and 7T MRI scanners. The research objectives are:
- Compare the relative accuracies of 7T and 3T MRI in detecting clinical osteoarthritis progression.
- Compare the quantitative MRI measures developed with the results acquired from the following two questionnaires: Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Visual Analogue Score (VAS).
- Measure the repeatability of 7T and 3T quantitative MRI methods developed in whole-joint knee imaging
- Optimize the quality and efficiency of 7T and 3T whole-joint knee MRI
Participants will be scanned at the 3T scanner at the Clinical Imaging Facility at Hammersmith Hospital and/or the 7T scanner at the LOCUS Center at St Thomas' Hospital. Knee osteoarthritis volunteers will be asked to fill out two questionnaires and will be scanned 4 times over a 2 year period (at enrolment, after 6 months, after 12 months and after 24 months) while healthy volunteers will be scanned once at enrolment. Both healthy volunteers and knee osteoarthritis patients will be asked to fill out MRI safety forms before entering the scanner room, and both groups will be scanned up to 90 minutes during each session.
Researchers will compare knee osteoarthritis patients with healthy volunteers to see how their knee anatomy and tissue properties differ.
