Clinical proton MR spectroscopy in central nervous system disorders.
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.
Demonstration of interstitial cerebral edema with diffusion tensor MR imaging in type C hepatic encephalopathy
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.
Relationships Between Choline Magnetic Resonance Spectroscopy, Apparent Diffusion Coefficient and Quantitative Histopathology in Human Glioma
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.
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.
Methodological consensus on clinical proton MRS of the brain: Review and recommendations
A consensus is presented on deficiencies in widely available MRS methodology and validated improvements that are currently in routine use at several clinical research institutions, and use of the semi‐adiabatic localization by adiabatic selective refocusing sequence is a recommended solution.
Magnetic resonance imaging in juvenile asymmetric segmental spinal muscular atrophy
Brain abscesses: etiologic categorization with in vivo proton MR spectroscopy.
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.
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
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.

Noninvasive imaging modalities such as computed tomography scan and magnetic resonance imaging (MRI) are routinely used in the diagnosis of neurotuberculosis, with MRI offering greater inherent sensitivity and specificity than CT scan.
