  1. Number in column indicates grade of stress injury. Last column indicates total number of stress injuries in the patient. The 3T images found two low grade stress injuries in the left foot of patient 4 which did not visualize in the 1.5 T images. (TIB = tibia, FIB = fibula, TAL = talus, CAL = calcaneus, NAV = naviculare, CUB = cuboideum, CM = medial cuneiforme, CI = intermediale cuneifrome, CL = lateral cuneiforme, MT1 = first metatarsal, MT2 = second metatarsal, MT3 = third metatarsal, MT4 = fourth metatarsa, MT5 = fifth metatarsal)
