| Popis: | Background/aim: CAIPIRINHA is a new technique in abdominal imaging. Pancreatic steatosis PS is a subject of increasing scientific interest. The aim of this study was to investigate the efficacy of the isotropic 3D-VIBE- CAIPIRINHA -DIXON technique on a new generation 3-tesla MR unit in the evaluation of PS.Materials and methods: In this retrospective study, the imaging findings of 49 patients with PS and 41 control subjects were examined. The pancreas-to-spleen ratio PSR , pancreas-to-muscle ratio PMR , and pancreatic signal intensity index PSII were defined as 3 new parameters and these indexes were calculated from the in-phase/out of phase 3D-VIBE- CAIPIRINHA-DIXON images. Results: The PSR, PMR, and PSII values were significantly different between the patient and control groups P = 0.001, P = 0.009, P < 0.001, respectively . Statistically significant differences were observed between patient and control groups for ROI measurements of fatty areas on these sequences/images: subtraction in-out P < 0.001 , T2W HASTE P < 0.001 , DIXON-fat P < 0.001 , fat-suppressed T1W P = 0.002 , and subtraction out-in P = 0.010 . Conclusion: Evaluation of PS with the 3D-VIBE-CAIPIRINHA-DIXON technique can be made rapidly and effectively. |
