Bias free estimates of the diffusional kurtosis in two minutes: Avoid solving the kurtosis tensor
نویسندگان
چکیده
Introduction Diffusion kurtosis tensor imaging provides additional information compared with diffusion tensor imaging [1,2]. Solving the kurtosis tensor, however, requires measurements in at least 15 diffusion-encoding directions as well as measurements with at least three or more b-values in each of these directions [2]. This leads to scanning times in the order of 6-10 minutes, which is often too long for incorporation in a routine clinical protocol. We suggest a method to estimate a bias free kurtosis value from only six diffusion encoding directions, thus enabling assessment of the kurtosis in less than two minutes of scan time.

Mapping the Orientation of White Matter Fiber Bundles: A Comparative Study of Diffusion Tensor Imaging, Diffusional Kurtosis Imaging, and Diffusion Spectrum Imaging.
BACKGROUND AND PURPOSE White matter fiber tractography relies on fiber bundle orientation estimates from diffusion MR imaging. However, clinically feasible techniques such as DTI and diffusional kurtosis imaging use assumptions, which may introduce error into in vivo orientation estimates. In this study, fiber bundle orientations from DTI and diffusional kurtosis imaging are compared with diffu...
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 کاملAltered microstructure in temporal lobe epilepsy: a diffusional kurtosis imaging study.
BACKGROUND AND PURPOSE Temporal lobe epilepsy is associated with regional abnormalities in tissue microstructure, as demonstrated by DTI. However, the full extent of these abnormalities has not yet been defined because DTI conveys only a fraction of the information potentially accessible with diffusion MR imaging. In this study, we assessed the added value of diffusional kurtosis imaging, an ex...
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 کاملQuantifying Microstructure in Fiber Crossings with Diffusional Kurtosis
Diffusional Kurtosis Imaging (DKI) is able to capture nonGaussian diffusion and has become a popular complement to the more traditional Diffusion Tensor Imaging (DTI). In this paper, we demonstrate how strongly the presence of fiber crossings and the exact crossing angle affect measures from diffusional kurtosis, limiting their interpretability as indicators of tissue microstructure. We allevia...
