Intrinsic macroscale oscillatory modes driving long range functional connectivity in female rat brains detected by ultrafast fMRI

Nature Communications, 2023
The mechanisms which generate fMRI signal correlations across the brain are not fully understood. Here, the authors record ultrafast fMRI signals in anesthetized female rats to demonstrate intrinsic macroscale oscillatory modes which drive correlated ...

The DAMASK trial protocol: a pragmatic randomised trial to evaluate whether GPs should have direct access to MRI for patients with suspected internal derangement of the knee [PDF]

, 2006
Background: Though new technologies like Magnetic Resonance Imaging (MRI) may be accurate, they often diffuse into practice before thorough assessment of their value in diagnosis and management, and of their effects on patient outcome and costs.

Autologous Serum Improves Yield and Metabolic Capacity of Monocyte-Derived Hepatocyte-Like Cells: Possible Implication for Cell Transplantation

Cell Transplantation, 2011
Hepatocyte-transplantation is a therapeutic approach for diverse acute and chronic liver diseases. As availability of primary cells is limited, there is an increasing demand for hepatocyte-like cells (e.g., neohepatocytes generated from peripheral blood ...

A method for improving the performance of gradient systems for diffusion-weighted MRI [PDF]

, 2007
The MR signal is sensitive to diffusion. This effect can be increased by the use of large, balanced bipolar gradients. The gradient systems of MR scanners are calibrated at installation and during regular servicing visits.

Microstructural parameter estimation in vivo using diffusion MRI and structured prior information. [PDF]

, 2016
Diffusion MRI has recently been used with detailed models to probe tissue microstructure. Much of this work has been performed ex vivo with powerful scanner hardware, to gain sensitivity to parameters such as axon radius.
