Objective To observe the signal intensity dynamic process of early Wallerian degeneration (WD) of the corticospinal tract (CST) in cat brain on 3D-TSE-T2 weighted imaging (3D-TSE-T2WI). Methods The origin cortex regions of the unilateral CSTs in 8 cats were cut off to establish the models of Wallerian degeneration, and longitudinal T2WI were performed repeatedly at 8 consecutive time points (before modeling and 2, 4, 6, 8, 10, 20 and 30 days after brain surgery). The values of T2 signal intensity of bilateral CSTs were obtained using a region of interest method. The ratios of T2 signal intensity (rT2s) between the affected and unaffected sides of the CSTs were calculated. Results During the first 4 days, there was no obvious abnormal signal on T2WI, and the rT2s did not change significantly in the degenerated CSTs. From 6 to 10 days, the rT2s decreased progressively with abnormal low signals on T2WI. From 10 to 30 days, the rT2s stabilized relatively still with low signals on T2WI, but on 30th day the rT2s began to increase. Conclusion T2WI can be used to detect early WD sensitively.
