摘　　要：目的探讨于MRI mDixon-quant技术在胰腺脂肪含量测定中的应用价值。方法共纳入237人,其中男性107名、女性130名。所有对象均进行上腹部3.0T MRI mDixon-quant扫描,并分别测量胰腺头、体、尾脂肪含量,取均值作为整个胰腺的最终脂肪含量。比较头、体、尾的脂肪含量有无统计差异,并按照性别、年龄分组,记录不同年龄段及性别下胰腺脂肪含量。结果两个观察者内的ICC分别为0.997和0.996;观察者间的ICC为0.989;胰腺头、体、尾部脂肪含量无统计学差异;237位受试者胰腺总体脂肪含量为3.33%(25分位值1.82%,75分位值6.16%)。结论采用MR mDixon-Quant技术可简便、精确测量胰腺脂肪含量,重复性和再现性都很高,可为胰腺脂肪沉积相关疾病的研究提供方法学基础。Objective To investigate the application value of MR mDixon-quant technique in accurate quantification of pancreatic fat content.Methods 237 subjects were studied in this researchMR mDixon-quant imagi,including 107 males and 130 females.All subjects underwent midsection ng,and pancreatic fat content was measured in head,body,and tail,respectively.The mean of head,body,and tail was taken as the final fat content of the whole pancreas.They were grouped and recorded according to their gender and age.Results The ICC in the observers was 0.997 and 0.996,respectively,which is 0.989 between observers.The fat content did not vary significantly between head,body,and tail in the pancreas.The median fat content of pancreatic was 3.33%(first quartile 1.82%,third quartile 6.16 ntification of pancreatic fat content by MR mDixon-quant technique was conveni%).Conclusion Quaent and accurate,having good repeatability and reproducibility.It can provide a methodological basis for the study of diseases related to pancreatic fat deposition.
