Monitor the reproducibility of MR spectroscopy acquisitions and analyses through routine scanning of the SPECTRE phantom.

The SPECTRE (Spectroscopy Reference) phantom is designed for Quality Assurance measurements of Magnetic Resonance Spectroscopy (MRS).  It contains a set of metabolites found within the brain at physiological concentrations and pH, all housed within a 180mm diameter HDPE sphere.  Up to 30 SPECTRE phantoms can be made from the same batch, providing identical phantoms for use in multi-centre studies.

SPECTRE uses a set of metabolites typically used in MRS QA; however, with the addition of GABA (gamma-Aminobytyric acid) at 2mM to allow performance testing of J-editing sequences.
