Diffusional kurtosis imaging of the developing brain.
BACKGROUND AND PURPOSE Diffusional kurtosis imaging is an extension of DTI but includes non-Gaussian diffusion effects, allowing more comprehensive characterization of microstructural changes during brain development. Our purpose was to use diffusional kurtosis imaging to measure age-related microstructural changes in both the WM and GM of the developing human brain. MATERIALS AND METHODS Dif...
متن کاملRobust Estimation of Kurtosis and Diffusion Tensors in Diffusional Kurtosis Imaging
Diffusion of water molecules in biological tissues is conventionally quantified via diffusion tensor imaging (DTI) [1]. DTI enables a Gaussian approximation to the probability distribution governing the random displacement of water molecules. In some circumstances of great interest, however, the displacement probability distribution can deviate considerably from a Gaussian form. Diffusional kur...

متن کاملNeuromyelitis optica: a diffusional kurtosis imaging study.
BACKGROUND AND PURPOSE Conventional MR imaging typically yields normal images of the brain or indicates lesions in areas of high aquaporin expression in patients with neuromyelitis optica. Diffusional kurtosis imaging was applied in patients with neuromyelitis optica to determine whether this technique could detect alterations in diffusion and diffusional kurtosis parameters in normal-appearing...
متن کاملDiffusional Kurtosis Imaging in Acute Human Stroke
The management of acute human stroke is a high-priority medical emergency. Thrombolytic therapy is now part of the standard of care in most major medical centers, and the selection of patients for these treatments depends on several clinical factors as well as brain imaging findings. Diffusion MRI combined with perfusion imaging are accepted imaging protocols used to characterize ischemic strok...
