目的:应用双能CT肌-水分离技术定量评估健康人腰椎旁肌的肌和水含量随年龄的变化规律。方法:回顾性分析125例健康人L1/2-L4/5椎间隙水平竖脊肌、L2/3-L5/S1椎间隙水平多裂肌及腰大肌的肌和水含量。比较青年组(20~39岁)、中年组(40~59岁)及老年组(60~89岁)在各椎间隙水平椎旁肌的肌和水含量差异。结果:多裂肌的肌含量:老年组于L3/4水平低于中年组(t=3.090,P=0.006),L4/5水平低于青年组(t=2.800,P=0.015),老年组于L5/S1水平分别低于青年组(t=3.191,P=0.004,)、中年组(t=3.239,P=0.004)。竖脊肌、腰大肌的肌含量不同年龄组各椎间隙水平差异无统计学意义(P>0.05)。多裂肌水含量:老年组于L2/3、L3/4水...

Objective:To quantitatively evaluate the changes of muscle and water content of lumbar paraspinal muscles in healthy participants with age by using dual-energy CT muscle-water decomposition technique.Methods:The data from 125 healthy participants who underwent lumbar spine examination using dual-energy CT were retrospectively collected.The participants were divided into three age groups:young(20~39 years old),middle-aged(40~59 years old),and elderly(60~89 years old)group.The measurement included muscle content and water content of the bilateral erector spinae muscles at L1-L2 to L4-L5 levels,a...
