Abstract Objective: To evaluate the clinical value of gradient reversal fat suppression technology(LIPO) in diffusion-weighted MR imaging of normal pancreas at 3.0T. Methods: DWI-LIPO and conventional DWI sequence(b values 800 s/mm2) were performed among twenty volunteers on a 3.0T whole-body MRI system. The ADC value and image quality, including SNR, blurring and artifact level, was evaluated by two experienced radiologists. One-way analysis and LSD test were used to compare DWI-LIPO sequence with conventional DWI sequence through the software SPSS 19.0. Results: There was no statistical difference between two different DWI sequences(P=0.211) in ADC value of normal pancreas. Normal pancreas in DWI with LIPO has more higher SNR than conventional DWI(P=0.000 2). Compared with conventional DWI sequence, there was significantly statistical difference between the artifacts and image blurring degree scores in DWI with LIPO(P=0.001, 0.009). Conclusion: LIPO technology improves the image quality of pancreas DWI at 3.0T MR.
