计算机断层扫描（CT）和磁共振成像（MRI）可以量化肌肉质量和质量。然而，目前尚不清楚CT和MRI衍生的测量是否可以互换使用。在这项前瞻性研究中，50名癌症筛查项目的连续参与者在同一天接受了低剂量胸部CT和MRI检查。测量脊柱旁骨骼肌的横截面积（CSA）。CT和MRI肌肉脂肪浸润（MFI）分别采用Hounsfield单位平均放射密度（HU）和质子密度脂肪分数（MRIPDFF）评估。CSA和MFI在CT和MRI之间高度相关(CSA: r=0.93， P
Computed tomography (CT) and magnetic resonance imaging (MRI) can quantify muscle mass and quality. However, it is still unclear if CT and MRI derived measurements can be used interchangeable. In this prospective study, fifty consecutive participants of a cancer screening program underwent same day low-dose chest CT and MRI. Cross-sectional areas (CSA) of the paraspinal skeletal muscles were obtained. CT and MRI muscle fat infiltration (MFI) were assessed by mean radiodensity in Hounsfield units (HU) and proton density fat fraction (MRIPDFF), respectively. CSA and MFI were highly correlated between CT and MRI (CSA: r=0.93, P
