诊断成像模式，如计算机断层扫描（CT）和磁共振成像（MRI），可用于评估体内肌肉质量。使用这些技术的定量评估是时间密集型和昂贵的，部分原因是广泛的后处理需求。本研究的目的是确定CT和MRI切片的子集是否会产生与完整切片数量相当的结果，用于测量糖尿病和周围神经病变患者足部固有肌的肌肉质量（肌肉退化率=脂肪体积/肌肉体积）。使用先前描述的方法获得CT（0.6 mm切片厚度）和MRI（3.5 mm切片厚度）扫描。将扫描期间采集的切片总数与使用部分切片的几种条件进行比较。Bland-Altman图和Lin的一致性相关系数用于检验一致性。使用至少三个切片的任何条件都与CT和MRI上的总切片数基本一致，几乎完全一致（Lin一致性相关系数范围：0.947 - 0.999）。在感兴趣区域的中间使用单个切片证明与切片总数的一致性较差至中等。这项研究的结果表明，使用有限数量的切片来量化CT或MRI上的肌肉退化率是一种可行的方法，可以在研究和临床环境中平衡测量准确性与可行性的综合需求。
Diagnostic imaging modalities, like computed tomography (CT) and magnetic resonance imaging (MRI), can be used to assess in vivo muscle quality. Quantitative assessment using these techniques is time-intensive and costly due in part to extensive post-processing needs. The purpose of this study was to identify whether a subset of slices on CT and MRI would yield comparable results to the full number of slices for a measure of muscle quality (muscle deterioration ratio = fat volume/muscle volume) in the foot intrinsic muscles of people with diabetes and peripheral neuropathy. CT (0.6 mm slice thickness) and MRI (3.5 mm slice thickness) scans were obtained using previously described methods. The total number of slices acquired during the scan was compared to several conditions using a portion of slices. Bland-Altman plots and Lin’s concordance correlation coefficient were used to test agreement. Any condition using at least three slices yielded substantial to almost perfect agreement with the total number of slices on both CT and MRI (Range of Lin’s concordance correlation coefficient: 0.947 −0.999). Using a single slice in the middle of the region of interest demonstrated poor to moderate agreement with the total number of slices. The findings of this study suggest that using a limited number of slices to quantify muscle deterioration ratio on CT or MRI is a viable way to balance the combined need for measurement accuracy with feasibility in research and clinical settings.
