目的应用Revolution CT物质分离技术探索腰椎椎旁肌内肌与脂含量随年龄的变化规律。方法回顾性分析125例接受Revolution CT腰椎能谱平扫的受试者,分别在肌-脂配对的基物质密度图上测量L1、2~ L4、5椎间隙水平的竖脊肌、L2、3~ L5/S1椎间隙水平的腰大肌以及多裂肌内的肌含量与脂含量,对上述数值进行统计学分析。结果中年组多裂肌L4、5、L5/S1水平脂含量显著高于青年组多裂肌同层面脂含量(P < 0.05),肌含量显著低于青年组同层面肌含量(P < 0.05),老年组多裂肌所有椎间隙水平脂含量均显著高于青年组与中年组多裂肌内脂含量(P < 0.05),肌含量显著低于青年组及中年组同层面肌含量(P < 0.05);中年组竖...

Objective To evaluate changes in muscle and fat contents oflumbar paraspinal muscles with aging by using Revolution CT material decomposition (MD) technique. Methods A retrospective analysis of 125 subjects who underwent Revolution CT gemstone spectral imaging non-enhancing scan for lumbar spine. The muscle and fat contents were measured for erector spinae muscle (ES) at each disc level from L1/2 to L4/5,psoas muscle (PS) and multifidus muscle (MS) from L2/3 to L5/S1 on muscle-based MD images and fat-based MD images respectively,differences of muscle and fat contents at each disc level and ine...
