Fast MR Spectroscopic Imaging
MR spectroscopic imaging (MRSI) has become widely available as a research tool for mapping tissue metabolic status. Clinical research applications have been limited by intrinsically low sensitivity and by time-consuming phase encoding techniques that are used with conventional MRSI. The long encoding times limit volume coverage, introduce motion sensitivity and tax patient tolerance. The increa...
متن کاملFast proton spectroscopic imaging using steady-state free precession methods.
Various pulse sequences for fast proton spectroscopic imaging (SI) using the steady-state free precession (SSFP) condition are proposed. The sequences use either only the FID-like signal S(1), only the echo-like signal S(2), or both signals in separate but adjacent acquisition windows. As in SSFP imaging, S(1) and S(2) are separated by spoiler gradients. RF excitation is performed by slice-sele...
متن کاملReproducibility of proton MR spectroscopic imaging findings.
PURPOSE To study the intraindividual, interindividual, and intraregional reproducibility of multisection proton MR spectroscopic imaging in healthy adults. METHODS Six subjects were studied three times with proton MR spectroscopic imaging. Multisection long-echo-time proton MR spectroscopic imaging permits simultaneous acquisition of N-acetylaspartate (NAA), choline-containing compounds (Cho)...
متن کاملProton MR spectroscopic imaging without water suppression.
To improve reproducibility in proton magnetic resonance (MR) spectroscopic imaging in human brain, simultaneous acquisition of the internal water reference and metabolite signals was evaluated. Measurements in healthy volunteers showed that the increase in dynamic range from signal oversampling was sufficient to avoid digitization errors. In addition, use of singular value decomposition techniq...
متن کاملLine Scan Proton Magnetic Resonance Spectroscopic Imaging
This thesis explores magnetic resonance (MR) imaging methodologies that provide in vivo spectroscopic information. To date such information has not been routinely acquired and used in diagnosis. The general objective of the thesis is to develop and implement new and fast MR spectroscopic imaging techniques that can be practically utilized to study spectroscopic information in vivo. This thesis ...
