图2 脊髓半切损伤4周后，大鼠脑的代表性的不同层的磁共振图像.在T2WI图像上勾画ROIs，并转移到mVD、Density和VSI图像上.CTX：皮质，包括初级运动皮质（M1）；IC：内囊；CP：大脑脚；PY：锥体

Fig. 2 Representative magnetic resonance images of different layers of a rat brain after spinal cord hemisection injury for four weeks. The ROIs were delineated on T2-weighted images and transferred to the mVD, Density and VSI images. CTX: cortex including primary motor cortex (M1); IC: internal capsule; CP: cerebral peduncle; PY: pyramid
