The aim of this study was to compare the reproducibility and accuracy of ADC measurements on scanners from different vendors with comparable acquisition protocols.. Five plastic tubes (cyclohexane, butanol, destilled water, n-hexadecane, ethanol) were examined with a PROPELLER-DWI sequence (b-values 0,800) in 1.5T scanners of two different vendors. The resulting mean values were compared with the temperature-adjusted literature data. Although both vendors use different approaches for diffusion preparation, the reconstructed ADC value agreed excellently with the reported values in the literature. Vendor-independency can be seen as one important step toward clinical standards in DWI imaging.
