Application of modern neuroimaging technology in the diagnosis and study of Alzheimer's disease

Neural Regeneration Research, 2021
Neurological abnormalities identified via neuroimaging are common in patients with Alzheimer’s disease. However, it is not yet possible to easily detect these abnormalities using head computed tomography in the early stages of the disease. In this review,

Intracranial yolk sac tumor in an adult patient: MRI, diffusion-weighted imaging and 1H MR spectroscopy features [PDF]

Vojnosanitetski Pregled, 2012
Introduction. Yolk sac tumors represent only 5%-7% of intracranial germ cell tumors, which comprise about 1% of all primary brain tumors in adults. Literature data about nonspecific imaging characteristics of these tumors are scant.

Fiber tracking in q-ball fields using regularized particle trajectories [PDF]

, 2005
Most of the approaches dedicated to fiber tracking from diffusion-weighted MR data rely on a tensor model. However, the tensor model can only resolve a single fiber orientation within each imaging voxel.
