Fig. 6From: Ex vivo MRI cell tracking of autologous mesenchymal stromal cells in an ovine osteochondral defect modelCross-sectional MRI images of the knee joints 7 days post cell delivery. a T1 MRI scans obtained using a 0.25-T Esaote MRI scanner and validated using a b MR750 3-T GE Healthcare scanner with T2 sequences. Red star represents areas of blooming artefact due to the presence of significant amounts of SPION-labelled cells whilst yellow arrow represents the site of the osteochondral defect and green star the site of the femoral patella joint. F = femur, T = tibia, M = meniscus, P = patella, FC = femoral condyleBack to article page
