Outcomes after central grey matter injury in term perinatal hypoxic-ischaemic encephalopathy

Central grey matter damage following perinatal hypoxia?ischaemia frequently leads to death or motor abnormality often with deficits in other developmental domains.

Magnetic resonance image enhancement using stochastic resonance in Fourier domain

In general, low-field MRI scanners such as the 0.5- and 1-T ones produce images that are poor in quality. The motivation of this study was to lessen the noise and enhance the signal such that the image quality is improved.

High-resolution in vivo diffusion tensor imaging of the injured cat spinal cord using self-navigated, interleaved, variable-density spiral acquisition (SNAILS-DTI)

Diffusion tensor magnetic resonance imaging (DTI) is useful for studying the microstructural changes in the spinal cord following traumatic injury; however, image quality is generally poor due to the small size of the spinal cord, physiological motion and susceptibility artifacts.

A new MRI approach for accurately implanting microelectrodes into deep brain structures of the rhesus monkey (Macaca mulatta)

? The accuracy of electrode implantation through MRI has been promoted. ? Slender rigid glass tubes were used as external markers. ? Tetrodes have been implanted in monkey's SC with the error <1mm. ? The new method is convenient, economical and universally available.

Spin-echo SS-PARSE: a PARSE MRI method to estimate frequency, R 2 and R 2 ′ in a single shot

These image parameters can be applied to fMRI research as well as a number of neuroimaging applications. Following a description of the signal model, this article demonstrates the performance of SE-SS-PARSE in simulations with different noise levels and in phantom experiments.

Caudate asymmetry: A neurobiological marker of moderate prenatal alcohol exposure in young adults

This study identified structural changes in the caudate nucleus in offspring of mothers who drank moderate levels of alcohol during pregnancy. In addition, the effect of duration of alcohol use during pregnancy was assessed.

Quantitative assessment of hypoxia in melanoma xenografts by dynamic contrast-enhanced magnetic resonance imaging: Intradermal versus intramuscular tumors

Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has been suggested to be a useful method for assessing the extent of hypoxia in tumors. In this study, we investigated whether differences in hypoxic fraction between tumors caused by the site of growth can be detected by DCE-MRI.

Precise correlation between MRI and histopathology – Exploring treatment margins for MRI-guided localized breast cancer therapy

Magnetic resonance imaging (MRI) is more often considered to guide, evaluate or select patients for partial breast irradiation (PBI) or minimally invasive therapy. Safe treatment margins around the MRI-visible lesion (MRI-GTV) are needed to account for surrounding subclinical occult disease.

Detection of radiation-induced lung injury in non-small cell lung cancer patients using hyperpolarized helium-3 magnetic resonance imaging

To compare hyperpolarized helium-3 magnetic resonance imaging (3He-MRI) acquired from non-small cell lung cancer (NSCLC) patients before and after external beam radiotherapy (EBRT).
