摘　　要：近年来因椎体退行性变、糖尿病及血液病等原因所致骨髓脂肪含量增加的现象逐渐受到关注,经研究脂肪或可成为病变治疗新靶点。磁共振最小二乘估算法和非对称回波迭代水脂分离(iterative decomposition of water and fat with echo asymmetry and least square estimation-iron quantification,IDEAL-IQ)技术是在IDEAL基础上发展起来的水脂分离技术,可精准量化脂肪含量,操作简便,准确性、重复性高。本文就磁共振IDEAL-IQ技术在腰椎及骨盆骨髓脂肪定量中的相关研究做以下综述。In recent years,the phenomenon of increased fat content in bone marrow caused by vertebral degeneration,diabetes and blood diseases has attracted increasing attention.Studies have shown that fat may be a new target for disease treatment.MR IDEAL-IQ technology is a new water-fat separation technology developed on the basis of IDEAL.This technology can accurately quantify fat content,easy to operate,high accuracy,repeatability.The application of MR IDEAL-IQ in fat quantification of lumbar and pelvic bone marrow is reviewed.
