Aims and objectives
Intriguing applications of Diffusion Weighted Imaging (DWI) in body imaging are the quantitative measures of the Apparent Diffusion Coefficient (ADC).
These measures are made on maps obtained by images with at least two different b-values.In order to obtain reliable quantitative ADC maps it’s mandatory to use fast imaging sequences; Echo Planar Images (EPI) sequences in particular [1].
Images obtained with this method are affected by chemical shift artefacts and require an effective fat suppression technique.Fat suppression methods are employed in abdominal DWI to reduce chemical shift artefacts while increasing contrast and reliability of the measured ADC.
The purpose of this work is to evaluate if organ specific ADCs are significantly altered by fat-suppression methods.
