A reproducible dynamic phantom for sequence testing in hyperpolarised 13C-magnetic resonance
Abstract
<jats:sec><jats:title>Objective</jats:title><jats:p>To develop a phantom system which can be integrated with an automated injection system, eliminating the experimental variability that arises with manual injection; for the purposes of pulse sequence testing and metric derivation in hyperpolarised 13C-MR.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>The custom dynamic phantom was machined from Ultem and filled with a nicotinamide adenine dinucleotide and lactate dehydrogenase mixture dissolved in phosphate buffered saline. Hyperpolarised [1-13C]-pyruvate was then injected into the phantom (n = 8) via an automated syringe pump and the conversion of pyruvate to lactate monitored through a 13C imaging sequence.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The phantom showed low coefficient of variation for the lactate to pyruvate peak signal heights (11.6%) and dynamic area-under curve ratios (11.0%). The variance for the lactate dehydrogenase enzyme rate constant (kP) was also seen to be low at 15.6%.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>The dynamic phantom demonstrates high reproducibility for quantification of 13C-hyperpolarised MR-derived metrics. Establishing such a phantom is needed to facilitate development of hyperpolarsed 13C-MR pulse sequenced; and moreover, to enable multisite hyperpolarised 13C-MR clinical trials where assessment of metric variability across sites is critical.</jats:p></jats:sec><jats:sec><jats:title>Advances in knowledge</jats:title><jats:p>The dynamic phantom developed during the course of this study will be a useful tool in testing new pulse sequences and standardisation in future hyperpolarised work.</jats:p></jats:sec>
