Repeatability and reproducibility of apparent exchange rate measurements in yeast cell phantoms using filter-exchange imaging

ConclusionsUsing ice –water and yeast cell-based phantoms, a protocol for the validation of FEXI pulse sequences was established for the assessment of stability, repeatability, reproducibility and directionality. In addition, a strong dependence of AXR on cell density and temperature was shown. As AXR is an emerging n ovel imaging biomarker, the suggested protocol will be useful for quality assurance of AXR measurements within a study and potentially across multiple sites.
