In the industrial production of hydrogen and of synthesis gas the water gas shift reaction represents an essential step for the overall process efficiency of the process by increasing the hydrogen yield and by adjusting the desired ratio of hydrogen

In 35 healthy volunteers 79 hydrogen spectra were measured from the parietal lobe, parieto-occipital lobe, frontal lobe, temporal lobe, thalamus and insular region. Voxels were selected with a double spin-echo sequence at TE 71, 135 and 270 ms. The s

Stimulated echos (STE) are frequently used for localization inin vivo spectroscopy. However, in theory the signal is reduced by a factor of 2 compared to spin echos. We have compared the STEAM technique and a method utilizing a double spin echo (DSE)

Magnetic resonance imaging (MRI) of the abdomen has been of limited clinical value because of long examination times, motion artifacts, and lack of suitable contrast agents [1–7]. Echo-planar MRI (EPI) and its derivatives have been developed to pro

Echo-planar imaging (EPI) is more sensitive to image artifacts than conventional imaging for two basic reasons; these are (a) reversal of every second echo and (b) the long readout (RO) period.

The time resolution of echoplanar imaging (EPI) allows the acquisition of imagesor = 100 ms, thus eliminating motion-related artifacts of the abdomen. Physical limitations are restrictions in signal-to-noise ratio and spatial resolution. Breath-held

Although the diagnostic application of echoplanar imaging (EPI) has until now been limited, recent technical advances provide anatomic resolution and signal-to-noise ratios comparable to that of conventional MR imaging. The purpose of this study was

The purpose of our study was to develop a strategy for optimized EPI in patients with abdominal disease to assess the clinical applicability of echoplanar MR imaging (EPI).

7 patients with drug-resistant temporal lobe epilepsy (TLE) and localized EEG-focus were investigated with a 4 Tesla whole body MR-scanner. Proton (1H) magnetic resonance (MR) spectra were analyzed quantitatively and compared to the healthy side. MRS
