Brainstem 1H nuclear magnetic resonance (NMR) spectroscopy: marker of demyelination and repair in spinal cord.

29 Sep 2009 Measuring in vivo spinal cord injury and repair remains elusive. Using magnetic resonance spectroscopy (MRS) we examined brainstem N-acetyl-aspartate (NAA) as a surrogate for spinal cord injury in two mouse strains with different reparative ... Read more...

Non-contrast-enhanced perfusion and ventilation assessment of the human lung by means of fourier decomposition in proton MRI.

30 Aug 2009 Assessment of regional lung perfusion and ventilation has significant clinical value for the diagnosis and follow-up of pulmonary diseases. In this work a new method of non-contrast-enhanced functional lung MRI (not dependent on intravenous or ... Read more...

Molecular neurodevelopment: an in vivo 31P-1H MRSI study.

11 Aug 2009 Synaptic development and elimination are normal neurodevelopmental processes, which if altered could contribute to various neuropsychiatric disorders. 31P-1H magnetic resonance spectroscopic imaging (MRSI) and structural magnetic resonance imaging ... Read more...
