Reduced signal in the superior sagittal sinus after USPIO injection on T2-weighted images. White arrows point to the superior sagittal sinus

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

Fig. 3

Quantitative analysis of mVD, Density, and VSI for each region of interest in the ipsilateral and contralateral brain regions of six rats after spinal cord hemisection injury for four weeks. CTX: cortex including primary motor cortex (M1); IC: internal capsule; CP: cerebral peduncle; PY: pyramid. Data were represented by mean ± standard deviation, ** p<0.01

Fig. 4

Immunofluorescence staining of representative brain region of a rat after spinal cord hemisection injury for four weeks. White arrows point reactive astrocytes. CTX: cortex including primary motor cortex (M1); IC: internal capsule; CP: cerebral peduncle; PY: pyramid

Fig. 5

Quantitative analysis of immunofluorescence intensity of CD31 and GFAP in the ipsilateral and contralateral brain regions of 6 rats after spinal cord hemisection injury for four weeks. CTX: cortex including primary motor cortex (M1); IC: internal capsule; CP: cerebral peduncle; PY: pyramid. Data were represented by mean ± standard deviation, ** p<0.01
