Colour-coded fractional anisotropy images: differential visualisation of white-matter tracts--preliminary experience.

Abstract:

:Diffusion-tensor analysis allows quantitative assessment of diffusion anisotropy. Fractional anisotropy (FA) is commonly used to quantify anisotropy. One of the limitations of FA imaging is, however, that it does not contain information about the directionality of anisotropy and it is therefore difficult to identify white-matter tracts on FA images. Our purpose was to describe a simple method of making composite images containing information about both magnitude and direction of diffusion anisotropy. The composite colour-coded FA images enabled us to identify different adjacent fibre bundles of similar degrees of diffusion anisotropy, and might be helpful in assessment of these fasciculi.

  • Cerebral hydatid cysts: CT findings.

    abstract::The CT features of cerebral hydatid cysts are divided into two groups. In the unilocular cases, the cyst is large, spherical in shape with sharply defined borders. One side of the cyst wall is very close to the calvarium. The cyst may calcify and may have septae inside. There is no enhancement with contrast media and ...
