Abstract

SUMMARY
The diagnosis of Autism based chiefly on clinical manifestations which are polymorphous. Some years recently owing to the fast development of diagnosis imaging particularly MRI, several articles had demonstrated the morphologic changing in autism. Rely on high spatial resolution, it can find the abnormality in the gray, white matter
based on diffusion sequence and displaying neural tractus in the predilection area of autism such as callosus corpus, frontal, temporal, amydal, ROI-based Volumetry, Voxel-based Morphometry, Surface-based Morphometry, Tensorbased morphology, DTI... The autistic pathologic changing can be found by decreasing of fractional anisotrope
FA, increasing of voxel-volume, thinning of the grey matter particular the neural fiber deficit on tractography. The equipement must be high MRI unit 3.0T and specific soft ware, however MRI can display the quality variation of the affection.
