Article Title: Maturation-Related Changes in T2 Relaxation Times of Cartilage and Meniscus of the Pediatric Knee Joint at 3 T
doi: 10.2214/AJR.18.20026
Figure Lengend Snippet: Sagittal gray-scale T2 map image through medial compartment of knee joint in skeletally immature 13-year-old boy illustrates method used for cartilage segmentation. Segmentation software semiautomatically outlined cartilage on each image slice, and dashed lines are used to divide cartilage into subregions. Subregions included patella and tibial plateau (light blue), trochlea (green), central femoral condyle (dark blue), and posterior femoral condyle (red). Green square allows manual movement of dashed lines; arrow and R denote right knee.
Article Snippet: A radiology resident with 3 years of clinical experience segmented the cartilage and meniscus of the entire knee joint on the T2 map images using custom-made semiautomated software developed in Matlab under the supervision of a fellowship-trained pediatric radiologist with 5 years of clinical experience and 3 years of research experience performing quantitative cartilage analysis.
