Diffusion MR tractography of the heart
Histological studies have shown that the myocardium consists of an array of crossing helical fiber tracts. Changes in myocardial fiber architecture occur in ischemic heart disease and heart failure, and can be imaged non-destructively with diffusion ...

ABSTRACT Background Retinopathy of prematurity (ROP) is a neurovascular disorder that may affect not only the retina but also the brain structures involved in visual processing. The relationship between ROP severity and the volumetric development of these regions remains unclear.

Using support vector machines with multiple indices of diffusion for automated classification of mild cognitive impairment [PDF]
Few studies have looked at the potential of using diffusion tensor imaging (DTI) in conjunction with machine learning algorithms in order to automate the classification of healthy older subjects and subjects with mild cognitive impairment (MCI).

Multiscale four‐dimensional imaging of cardiac remodelling after myocardial infarction
Abstract figure legend Multiscale 4D imaging framework for integrated phenotyping of post‐infarction remodelling. Myocardial infarction triggers dynamic changes across mechanical, haemodynamic and biological axes, progressing from acute injury and inflammation to extracellular matrix remodelling and scar maturation.

Different patterns of white matter degeneration using multiple diffusion indices and volumetric data in mild cognitive impairment and Alzheimer patients [PDF]
Alzheimeŕs disease (AD) represents the most prevalent neurodegenerative disorder that causes cognitive decline in old age. In its early stages, AD is associated with microstructural abnormalities in white matter (WM).

ABSTRACT We present p‐Brain, a modular, open‐source framework for reproducible, automated quantitative DCE‐MRI at scale. Rather than a fixed pipeline, p‐Brain is built from interchangeable stages (ingestion, T1/M0$$ {T}_1/{M}_0 $$ fitting, vascular and tissue ROI extraction, signal‐to‐concentration conversion, kinetic modeling, and quality control ...

Mental Scene and Memory Construction and the Hippocampus
ABSTRACT A neurocomputational theory of scene and memory construction during memory recall, prospective thinking, and autobiographical memory is described. The theory describes the nature of the representation of scenes using spatial view cells in a continuous attractor network in the medial parahippocampal cortex, and how the location in the scene ...

ABSTRACT Purpose To jointly reconstruct high‐resolution diffusion‐weighted volumes and eliminate slab‐boundary artifacts while preserving fine anatomical detail from undersampled 3D multi‐slab k‐space acquisitions. Methods A bilinear forward model was formulated to describe the 3D multi‐slab acquisition, treating the image volume and slab excitation ...

In vivo submillimeter diffusion MRI dataset of 9 macaque brains curated for tractography
In vivo diffusion magnetic resonance imaging (MRI) is critical to access detailed information about the brain microstructure and connectivity. In non-human primates (NHPs), especially macaque monkeys, such acquisitions should be carried out at a ...

ABSTRACT Arachnoid cysts are most commonly asymptomatic and usually do not need any active treatment. Currently, psychiatric symptoms are seldom taken into consideration during treatment evaluations in this patient population. We present this case of a young man who was treated in our hospital for signs of depression.
