T2MES: a reference phantom for cardio MRI


In an international collaboration led by University College London, a reference phantom for quantitative MRI imaging of the heart, called T2MES, was developed and tested over twelve months. Spatially resolved measurements of the transverse relaxation time T2 provide clues to edema, inflammation, and other diseases of the myocardium, but in clinical practice measurement results are often influenced by the scanners and MR sequences used. The T2MES phantom contains a set of reference samples with known T2 values in the physiologically relevant regime and is thus an important tool for quality control in cardio MRI. PTB and likewise the US NIST contributed precise data on the long-term stability of the phantom and the temperature dependence of the measured values to this study. The results have now been published in the Journal of Cardiovascular Magnetic Resonance (Topriceanu CC et al, Developing a medical device-grade T2 phantom optimized for myocardial T2 mapping by cardiovascular magnetic resonance. doi: 10.1186/s12968-023-00926-z).
