Fig. 1From: Fat-suppressed T2 mapping of human knee femoral articular cartilage: comparison with conventional T2 mappingNine ROIs drawn on femoral cartilage T2 mapping. Dashed lines indicates diameter line of circle connected two most protruding points and it’s bisecting perpendicular lines. Lines drawn at the angle of ± 10°, 30°, 50°, 70°, + 90° and + 110°, respective to perpendicular line. ROIs were drawn on anatomical T2 weighted source image (a) including full thickness cartilage defined by reference lines and matched to the T2 mapping (b)Back to article page
