大量的研究使用腹部计算机断层扫描（CT）来量化身体成分，并使用不同的软件程序来执行这些分析。因此，这种比较对于使研究人员了解更易于访问的软件的性能非常重要。选择来自巴西单一中心的54例肥胖（BMI 30 - 39.9 kg/m2）、久坐的成年人（24-41岁）腹部CT扫描患者。比较两种软件程序：Slice-O-Matic (Tomovision, Canada) 5.0版和OsiriX 5.8.5版。使用标准Hounsfield单位（HU）对身体成分分析进行分割（脂肪组织：-190至+30，骨骼肌：-29至+150），并在显示两横突的切片上测量第三腰椎（L3）中段水平。一致性分析的Bland-Altman极限被用来评估Slice-O-Matic和OsiriX之间的一致性水平。共有54名参与者接受了评估，其中大多数为女性（69%），平均年龄为31.3岁（SD 6.5），肥胖I级最普遍（74.1%）。在Bland-Altman分析中，muscle mass tissue，内脏脂肪组织和皮下脂肪组织的切片- o - matic和OsiriX分析的一致性非常好（≥0.954），p值< 0.001。这些发现表明，Slice-O-Matic和OsiriX软件在肥胖患者的骨骼肌和脂肪组织测量以及肌肉减少症诊断方面是一致的，这表明在该人群的身体组成研究和临床实践中具有良好的适用性。
A large number of studies have used abdominal computed tomography (CT) to quantify body composition, and different software programmes have been used to perform these analyses. Thus, this comparison is important to enable researchers to know the performance of more accessible software. Fifty-four abdominal CT scans of obese (BMI 30 to 39.9 kg/m2), sedentary adults (24-41 years) patients from a Brazilian single center were selected. Two software programs were compared: Slice-O-Matic (Tomovision, Canada) version 5.0 and OsiriX version 5.8.5. The body composition analysis were segmented using standard Hounsfield unit (HU) (adipose tissue: -190 to +30 and skeletal muscle: -29 to +150) and measured at the mid third lumbar vertebra (L3) level on a slice showing both transversal processes. Bland-Altman limits of agreement analyses were used to assess the level of agreement between Slice-O-Matic and OsiriX. A total of fifty-four participants were evaluated, with majority women (69%), mean of age 31.3 (SD 6.5) years and obesity grade I most prevalent (74.1%). The agreement, in Bland-Altman analysis, between Slice-O-Matic and OsiriX analisys for the muscle mass tissue, visceral adipose tissue and subcutaneous adipose tissue were excellent (≥ 0.954) with P-values < 0.001. These findings show that Slice-O-Matic and OsiriX softwares agreement in measurements of skeletal muscle and adipose tissue and sarcopenia diagnosis in obese patients, suggesting good applicability in studies with body composition in this population and clinical practice.
