Demonstration of interstitial cerebral edema with diffusion tensor MR imaging in type C hepatic encephalopathy
TLDR
The increase in MD with no concomitant changes in FA in cirrhosis with minimal or early HE indicates the presence of reversible interstitial brain edema.
Clinical proton MR spectroscopy in central nervous system disorders.
TLDR
A summary of brain disorders in which proton (hydrogen 1 [(1)H]) magnetic resonance (MR) spectroscopy has an impact on patient management, together with a critical consideration of common data acquisition and processing procedures is presented.
Relationships Between Choline Magnetic Resonance Spectroscopy, Apparent Diffusion Coefficient and Quantitative Histopathology in Human Glioma
TLDR
The results indicate that both ADC and spectroscopic choline measures are related to glioma cell density and may prove useful for differentiating dense cellular neoplastic lesions from those that contain large proportions of acellular necrotic space.
Imaging features of central nervous system fungal infections.
TLDR
Although almost any fungus may cause encephalitis, cryptococcal meningoencephalitis is most frequently seen, followed by aspergillosis and candidiasis and the biology, epidemiology and imaging features of the common fungal infections of the CNS will be reviewed.
Magnetic resonance imaging in juvenile asymmetric segmental spinal muscular atrophy
TLDR
MRI done in neck flexion may have diagnostic significance in juvenile asymmetric segmental spinal muscular atrophy and a large posterior epidural space was visible which showed enhancement after gadolinium-DTPA administration.
Brain abscesses: etiologic categorization with in vivo proton MR spectroscopy.
TLDR
It is possible to differentiate anaerobic from aerobic or sterile brain abscesses on the basis of metabolite patterns observed at in vivo proton MR spectroscopy, and this information may be useful in facilitating prompt and appropriate treatment of patients with these abscesss.
Serial changes in the white matter diffusion tensor imaging metrics in moderate traumatic brain injury and correlation with neuro-cognitive function.
TLDR
DTI demonstrates axonopathy in the acute stage, as well as at secondary stages, at 6 months post-injury in the corpus callosum and peri-ventricular white matter in regions of normal-appearing white matter on conventional MRI.
Diffusion tensor imaging of the developing human cerebrum
TLDR
The studies suggest that the DTI‐estimated anisotropy could be useful in following neuronal migration, cortical maturation, and associated changes in the germinal matrix during early brain development.
Diffusion tensor fractional anisotropy of the normal‐appearing seven segments of the corpus callosum in healthy adults and relapsing‐remitting multiple sclerosis patients
To investigate the utility of whole‐brain diffusion tensor imaging (DTI) in elucidating the pathogenesis of multiple sclerosis (MS) using the normal‐appearing white matter (NAWM) of the corpus…
Comparative evaluation of corpus callosum DTI metrics in acute mild and moderate traumatic brain injury: Its correlation with neuropsychometric tests
TLDR
It is concluded that DTI abnormalities in the regions of CC were more in patients with moderate TBI compared to mild TBI and this was associated with relatively poor neuropsychological outcome 6 months post-injury.
