Quantitative bilateral knee MRI and whole femoral cartilage analysis is currently limited by costs and scan time. We propose a rapid, simultaneous bilateral knee MRI protocol followed by a fully automated pipeline to perform quantitative T2 analysis of the whole femoral cartilage plate of both knees. Five healthy subjects and a subject with an ACL reconstruction were scanned in this study and the results demonstrated high scan-rescan repeatability and a good agreement between manual and automatic segmentation. The proposed acquisition method with automated analysis may make bilateral imaging more feasible and efficient for use in longitudinal and cross-sectional studies.
