초록
This study obtained data by applying four types of techniques (1, 4NEX, NT and RT)of abdominal Diffusion MRI as a Free Breaching technique. All techniques wanted to apply theb-value (s mm-2) value up to 0~250 to determine the optimum value. A total of 30 normal volunteerswere targeted and used devices carry out by Ingenia 3.0 T CX Phillips. Quantitative and qualitativeassessment results were shown in the order NT>RT>1NEX>4NEX (p<0.05). However, NT,RT, and 4NEX had variability with respect to noise in breathing and image, but failed to achievesignificant results (p>0.05). In conclusion, the navigator technique was given the most advantage bytechnical comparisons. Based on this technique, we hope that it will be clinical basic data.
