Abstract:
ObjectiveTo explore the effect of low-fat and low-energy diet on the ultrasound examination of liver， gallbladder and pancreas of participants. MethodsFrom January 2020 to September 2020，a total of 30 participants were enrolled in this study. Using self-controlled research method， firstly， ultrasound scans were performed to them for scanning some organs （such as pancreas， left liver and gallbladder） after fasting more than 8 hours， then the participants were told to eat the low-fat and energy foods （steamed bread and porridge）， and five times of the same ultrasound scans were performed to them at 0.5 h， 1 h， 2 h， 3 h and 4 h after the meal. Every participant was tested in the above 6 groups. The ultrasound images were blindly evaluated， and gallbladder volumes were compared by two sonographers. The single-factor method of repeated measurement was used to evaluate the ultrasound image qualities of different groups and to compare the gallbladder volumes. ResultsThe difference had no statistical significance in imaging quality of pancreas and left liver between each postprandial group and fasting group （P > 0.05）. Among the most concerned gallbladder ultrasound image quality， the difference had no statistical significance between groups （F=0.7， P=0.6）. For the percentage of gallbladder volume， the difference had no statistical significance between groups （F=1.8， P=0.2）. ConclusionCompared with the ultrasound examination under an 8-hour fasting state， the ultrasound images of abdominal organs （such as liver， pancreas and gallbladder） and the gallbladder volumes are not affected by the low-fat and low-energy diets.
