Magnetic resonance imaging and T2 relaxometry of human median nerve at 7 Tesla

Measurements of T2 relaxation times in tissues have provided a unique, noninvasive method to investigate the microenvironment of water molecules in vivo. As more clinical imaging is performed at higher field strengths, tissue relaxation times need to be re ...

ANa3M7(PO4)6 (A = K, Rb, Cs and M = Mn, Fe, Co): Three-dimensional transition metal phosphates exhibiting low-dimensional magnetic anomalies

Wendy Lee Queen

We have an extensive interest in cryst. solids contg. magnetic nanostructures. The chem. systems we have paid special attention to thus far include transition-metal-contg. oxy compds., such as silicates, phosphates and arsenates. The oxy anions, like org. ...

Spatio-temporal coupling of the electric and hemodynamic brain responses in humans

Roberto Martuzzi

Our comprehension of human brain functions and their dynamics has been dramatically improved by recent developments in non-invasive imaging techniques. These methods can be divided into two different categories, according to the nature of the measured sign ...

Effect of acute hyperglycemia on visual cortical activation as measured by functional MRI

Rolf Gruetter

To determine whether acute hyperglycemia changes the hyperemic response to functional activation of brain, the area and magnitude of the activation were measured in healthy volunteers maintained at euglycemia and then at hyperglycemia using the hyperglycem ...
