Single-Sided Magnet System for Quantitative MR Relaxometry and Preclinical In-Vivo Monitoring.

Objective: We have developed a single-sided magnet system that allows Magnetic Resonance relaxation and diffusion parameters to be measured.

Methods: A single-sided magnet system has been developed, using an array of permanent magnets. The magnet positions are optimised to produce a B magnetic field with a spot that is relatively homogenous and can project into a sample.

Phosphorus magnetic resonance spectroscopic imaging using flyback echo planar readout trajectories.

Object: To present and evaluate a fast phosphorus magnetic resonance spectroscopic imaging (MRSI) sequence using echo planar spectroscopic imaging with flyback readout gradient trajectories.

Materials And Methods: Waveforms were designed and implemented using a 3 Tesla MRI system. P spectra were acquired with 2 × 2 cm and 3 × 3 cm resolution over a 20- and 21-cm field of view and spectral bandwidths up to 1923 Hz.

(1)H-MR imaging of the lungs at 3.0 T.

Background: One disadvantage of magnetic resonance imaging (MRI) is the inability to adequately image the lungs. Recent advances in hyperpolarized gas technology [e.g.
