摘要目的探究注射钆剂对T2*校正和估算的多回波重建技术用于肝脏脂肪定量是否有影响。方法 48例病人进行了3.0 T MRI检查,在注射钆喷酸葡胺(0.1 mmol/kg)前行1次,注射后行2次肝脏脂肪定量研究序列扫描。使用单因素重复测量的方差分析和两两比较法评估3次扫描脂肪分数 Abstract Objective To investigate whether gadolinium injection has an effect on the quantification of liver fat in T2 * corrected and estimated multi-echo reconstruction. Methods Forty-eight patients underwent 3.0 T MRI examinations. One injection of gadopentetate dimeglumine (0.1 mmol / kg) followed by two sequential quantitative liver scan studies. ANOVA and one pairwise comparisons using one-way repeated measures were used to assess the 3-scan fat fraction
