BACKGROUND AND PURPOSE We report on the use of line scan diffusion magnetic resonance imaging in the evaluation of spinal cord infarctions. METHODS Data on 19 patients with clinical findings consistent with spinal cord infarctions and abnormal findings on line scan diffusion imaging were reviewed. The Apparent Diffusion Coefficient (ADC) measurements for the normal spinal cord and for the are...

Purpose As DWI is increasingly implemented into routine protocols of abdominal MRI, positive findings both in expected as in unexpected locations become more common and might constitute diagnostic problems especially in patients with suspected benign disease. The aim of our retrospective study was to investigate the potential pitfalls of false positive findings in abdominal DWI by identifying b...

Lhermitte-Duclos disease, also known as dysplastic cerebellar gangliocytoma, is a rare cerebellar benign tumor with characteristic appearance of thickened cerebellar folia giving a laminated or striated appearance, quite diagnostic of the condition. We had seen a patient with medulloblastoma with imaging findings suspicious for thickened cerebellar folia reminiscent of Lhermitte-Duclos disease....

This article provides NODDI diffusion metrics in the brains of 52 healthy participants and computer simulation data to support compatibility of hybrid diffusion imaging (HYDI), "Hybrid diffusion imaging"[1] acquisition scheme in fitting neurite orientation dispersion and density imaging (NODDI) model, "NODDI: practical in vivo neurite orientation dispersion and density imaging of the human brai...

High b value diffusion-weighted images sampled at high angular resolution were analyzed using a composite hindered and restricted model of diffusion (CHARMED). Measurements and simulations of diffusion in white matter using CHARMED provide an unbiased estimate of fiber orientation with consistently smaller angular uncertainty than when calculated using a DTI model or with a dual tensor model fo...

and Density of Axons in Neuronal Tissue P.J. Basser, T. Blumenfeld , G. Levin, Y. Yovel, Y. Assaf, STBB/LIMB/NICHD, NIH; Department of Neurobiochemistry, Tel Aviv University Discussion The experimental determination of the diameter distribution, p(d), of emulsions and droplets has long been studied using NMR methods (see (1,2)). In these experiments, p(d) is estimated from PFG data by assuming ...

Introduction The assessment of local diffusion anisotropy in tissue using diffusion tensor imaging (DTI) is known to be problematic in regions that contain an admixture of tissue types or multiple fiber orientations. One approach to ameliorating this problem is to acquire high angular resolution qspace data, augmented with more sophisticated analysis schemes using higher order tensor models. Ho...
