详细
论证。由于在对抗COVID-19的过程中使用胸部计算机断层扫描的频率越来越高,因此有必要应用低剂量计算机断层扫描(LDCT)来减少患者身体的剂量负荷,同时保持研究的诊断价值.然而,在已发表的文献中未发现有关患者体重指数对COVID-19患者LDCT诊断准确性影响的数据。
目的是评估患者的BMI对放射科医生在解释COVID-١٩相关肺炎的标准和低剂量胸部CT扫描时在٠-٤视觉半定量CT评分上的一致程度的影响。
材料与方法。一项回顾性多中心研究,其中在一次访问时每位参与者接受了两次连续的胸部检查,使用标准和低剂量方案。对标准和低剂量胸部CT扫描的肺部和软组织核素的解释是以视觉半定量的CT ٠-٤尺度进行的。每个方案的数据根据体重指数的值进行分组(病理学阈值等于公斤/平方米)。协议是根据二元和加权分类计算的。通过方差单因素方差分析来评估各组平均值之间是否存在统计学上的显著差异。
结果。在患者总数(n=231)中,٢٣٠人符合确立的研究纳入标准。专家为每位患者处理了٤项标准和低剂量计算机断层扫描研究,包括肺和软组织卷积核。体重正常的患者比例为 ٣١٪(٧١ 人),样本的中位体重指数中位为 ٢٧.٥(١٨.٣;٤٨.٣)公斤/平方米。无论是二元分类还是加权分类,组间配对比较未发现统计学上的显著差异(p值分别为٠.٠٩和٠.١٢)。超重患者组根据肥胖程度进一步划分,但研究结果对这种划分是不变的(没有统计学上的显着差异:身体质量参数最大不同组别»正常»和»٣度肥胖»的p值为٠.١٧)。
结论。患者的体重指数不影响在٠-٤的视觉半定量CT等级上对 COVID-١٩胸部标准和低剂量计算机断层扫描的解释。
