Synopsis

ADC estimations are still known to be influenced by the content of fat. Fat suppression is normally applied in order to avoid the ADC measurement with fat contamination. The aim of this study was to evaluate the fat effect on ADC measurement by EP-DWI and PROP-DWI combined with different fat suppression techniques using a fat-water phantom with different fat fractions. Our results suggest that the ADC measurement is affected by the fat fraction and the MR sequences but not the fat suppression methods in EP-DWI.
