Figure 1.
The representative b0 image (f), DTI metrics (FA, MD, AD, and RD, a-d) images and GQI metrics (NQA, iso, and Color-QA, e, g, h) images with the b value of 1000 s/mm2 at 45 μm isotropic resolution (protocol 2). The image intensity variations of different connective tissues are apparent in b0 images (f). Compared to PCL (green arrow, a), the FA values are lower in muscle, growth plate, and articular cartilage (red arrows, a). Compared to PCL (green arrow, b), the MD values are higher in muscle, growth plate, and articular cartilage (red arrows, b). Different connective tissues can also be distinguished in the Color-QA images due to different fiber orientations (h).
