using a quadrature surface coil. Upper Left: 3T, VOI=20x20x20 mm in parietal WM, TR/TE=2000/6, BW=2kHz, 256 scans; Lower Left: 7T, VOI=30x15x30 mm in occipital GM, TR/TE=4000/5.7, BW=4kHz, 64 scans. Data processing consisted of zero-filling up to 16-k data points, shifted Gaussian weighting of the FID, Fourier transformation, and phase correction. Right: Corresponding fitted curves using LCModel. Note the excellent agreement between the data (black line) and the fits (red line) also illustrated by the small fit residuals seen above the fits. The SNR calculated by LCModel was 47 for both, the 3T and 7T spectra.

MR spectroscopy of the human brain with enhanced signal intensity at ultrashort echo times on a clinical platform at 3T and 7T.
Recently, the spin-echo full-intensity acquired localized (SPECIAL) spectroscopy technique was proposed to unite the advantages of short TEs on the order of milliseconds (ms) with full sensitivity and applied to in vivo rat brain. In the present study, SPECIAL was adapted and optimized for use on a clinical platform at 3T and 7T by combining interleaved water suppression (WS) and outer volume s...

Susceptibility-weighted imaging (SWI) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. It is a new art which evaluates and exploits the properties of blood, iron and other tissues. It is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3D fully velocit...

متن کاملImproved Spectral Quality Through Enhanced Shimming on a Clinical Platform at 3T and 7T
Introduction Increased spectral resolution and signal-to-noise ratio (SNR) and additional metabolite information not available at B0 = 1.5T are some of the benefits of magnetic resonance spectroscopy (MRS) at higher fields (≥3T) that enhance its attractiveness as an investigational tool for clinical use. However, to obtain high-quality MR spectra, reliable localized shimming is an essential pre...
