T1 relaxometry of crossing fibres in the human brain
A comprehensive tract-based characterisation of white matter should include the ability to quantify myelin and axonal attributes irrespective of the complexity of fibre organisation within the voxel. Recently, a new experimental framework that combines inversion recovery and diffusion MRI, called inversion recovery diffusion tensor imaging (IR-DTI), was introduced and applied in an animal study...
متن کاملMathematics of Crossing Fibres
This chapter looks at the problem of crossing fibres in diffusion MRI of the brain. Diffusion tensor imaging only gives us a single fibre direction, but fibres within single image voxels can adopt complex configurations. In particular, fibre crossings cause problems in diffusion tensor imaging that can result in failure of tractography or misleading indices of tissue integrity. Here we will stu...
متن کاملThe Enigma of Human T-Cell Leukemia Virus Type-1 (HTLV-1) Infection in Iran
Human T-cell lymphotropic virus type-I (HTLV-I) was the first human retrovirus associated with malignancy. The prevalence of HTLV-I infection varies significantly in different regions of the world. In this study, the prevalence of HTLV-I infection among ethnic Jews living in Shiraz, South of Iran, was investigated. 286 blood samples were obtained. HTLV-1 antibody assay on serum samples was d...

متن کاملEvaluating the Frequency of Human T-Lymphotropic Virus Type 1 Infection in Iranian Population
Background: Human T-cell lymphotropic viruses 1 (HTLV1) is endemic in specific regions. We aimed to determine the prevalence of HTLV I infection among blood donors in southeast Iran. Methods: This cross-sectional study was conducted between April 2005 and March 2015. Sera were collected from blood donors and were tested for the presence of HTLV1 specific antibody using ELISA. Reactive sample...
