Simultaneous Bilateral Knee MR Imaging
Osteoarthritis (OA) remains a tremendous burden to society, affecting the majority of the population by age 65. OA is commonly a bilateral disease. While long scan time and costs have precluded separate scanning of both knees in clinical MRI, there is evidence that bilateral examinations are beneficial for evaluation of OA changes, especially for longitudinal studies. In this work, we develop a bilateral coil-array setup to scan both knees simultaneously with similar scan time and image quality compared to single knee acquisitions. Further, this method was also able to maintain quantitative accuracy for bilateral knee scans which is vital for detection of early disease changes. Simultaneous imaging of both knees can improve the value of MRI knee evaluations; providing an internal control for clinical evaluation of pathology as well as helping reduce costs and improve continuity in research studies.
