Abstract
Objective: To discuss the imaging characteristics of cerebral heterotopic gray matter tissues and the white matter fiber bundle on peri-heterotopic gray matter in MRI diffusion tensor imaging (DTI). Methods: Ten patients with heterotopic gray matter confirmed by MRI were examined DTI. To observe the white matter fiber bundles in peri-heterotopic gray matter,and the fractional anisotropy (FA) values were measured on the heterotopic gray matter and the surrounding white matter. In addition, the FA value of the contralateral normal cerebral white matter and gray matter were measured, respectively, to compared the FA values between the white matter fiber bundle on peri-heterotopic gray matter and the contralateral normal cerebral white matter. The heterotopic gray matter were compared with the normal gray matter area. Results: Ten patients with Ⅰ type in 2 cases; Ⅱ type in 5 cases; Ⅲ type in 1 case; Ⅳ type in 2 cases. There was basic change of the white matter fiber bundle at peri-heterotopic gray matter appeared as displaced or gathering together damage; there was no significant difference for FA value between the white matter fiber bundle at the peri-heterotopic gray matter and the contralateral normal position cerebral white matter(T=-0.435, P=0.669); the FA value between ectopie location of gray matter and normal gray area had no significant difference (T=-0.000, P=1.000). Conclusion: The white matter fiber bundle on peri-heterotopic gray matter has morphological abnormality, FA value has no significant decrease compared with that of the contralateral white matter fiber tracts; DTT can clearly show the direction and morphology of white matter in the ectopic gray matter.关键词
