摘要目的展示使用化学位移MR影像脂-水分离法定量估计肝组织内经导管输入碘油的可行性。材料与方法研究遵循学院动物保护与使用委员会的指南进行。首先行质子核MR波谱扫描以确定碘油波谱峰与相对波幅。然后制做碘油-水容量分数逐步增大的模型。使用多回波化学位移脂-水分离法对每
Abstract Objective To quantitatively estimate the feasibility of transcatheter lipiodol infusion in liver tissue using chemical shift MR imaging and lipid-water separation. Material and methodological studies followed the guidelines of the College Animal Protection and Use Committee. First, proton MR spectroscopy scan to determine the iodine oil peaks and relative volatility. Then make lipiodol - water volume fraction of the model gradually increased. Use multiple-echo chemical shift lipids-water separation method for each
