| 目的 比较进食高蛋白高脂肪食物与空腹状态下MR胸导管成像（MRTD）图像质量的差异。方法 将70例继发性下肢淋巴水肿患者随机分为空腹组和高蛋白高脂肪组，分别应用重T2W水成像技术进行MRTD。将所获得的胸导管图像分成腹段、胸段下1/2、胸段上1/2、颈段，分别进行图像质量评分（0~2分），记录2组患者胸导管各段评分情况，并计算每幅图像4个节段总评分。采用秩和检验比较2组间各段评分差异，以独立样本t检验比较2组总评分。结果 2组胸导管显示满意率（4段总评分≥ 4分）均为97.14%（34/35），高蛋白高脂肪组和空腹组平均评分分别为（6.37±1.37）分和（6.43±1.40）分（t=0.17，P=0.86）。2组间胸段下1/2、胸段上1/2和颈段评分差异均无统计学意义（P=0.28、0.40、0.05），腹段差异有统计学意义（P=0.01）。结论 空腹或高蛋白高脂肪饮食于MR胸导管整体显示无差异，高蛋白高脂肪饮食对MRTD显示胸导管腹段效果更佳。 |

| Objective To compare the image quality of MRI of thoracic duct (MRTD) under high-protein high-fat diet and fasting state. Methods Seventy patients with secondary lymphedema of lower extremity were randomly divided into fasting group and high-protein high-fat group. MRTD using heavy T2W imaging was performed in all patients. The images of thoracic duct were divided into four segments, i. e. abdominal segment, lower thoracic segment, upper thoracic segment and neck segment, and the scores of image quality (0-2) of each thoracic duct segment in two groups were evaluated and recorded, respectively. The total scores of 4 segments of images in the two groups were calculated. Rank sum test was used to compare the scores of each segment between the two groups. The differences of total scores between the two groups were compared with independent sample t test. Results The image satisfaction rate of thoracic duct of the two groups (the total score was ≥ 4) was both 97.14% (34/35). The average score of fasting group was 6.43±1.40, and of the high-protein high-fat group was 6.37±1.37 (t=0.17, P=0.86). There was no significant difference of scores between the upper, lower thoracic segment nor cervical segment (P=0.28, 0.40, 0.05), while there was statistical significant difference of abdominal segments between the two groups (P=0.01). Conclusion There is no significant difference in the overall display of thoracic duct between fasting and high-fat high-protein diets. High-protein high-fat diets has better display effect on abdominal segment of thoracic duct. |
