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

CONCLUSIONS: Using 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 novel imaging biomarker, the suggested protocol will be useful for quality assurance of AXR measurements within a study and potentially across multiple sites.PMID:37436611 | DOI:10.1007/s10334-023-01107-w
