The use of CXR in the ICU has been debated for several years. Its diagnostic accuracy in critically ill patients can be limited for several reasons. In ICU patients, the presence of internal and external medical devices presents a specific challenge, as patient positioning and other factors limit the ability to complement the antero-posterior projection with a lateral-lateral scan.Several societies recommend abandoning the practice of requiring daily CXR in ICU patients; however, the overall number of prescribed CXR has seen only a modest reduction over the last decades [17]. Despite being the most used radiographic exam in critically ill patients, it is associated with only around 2% the cumulative radiations dose received during the ICU stay, which are almost exclusively due to CT examinations associated with high per-exam doses, even though these represent only 12% of the performed exams [18].During the COVID-19 pandemic CXR were widely used for their availability, and their visual assessment and scoring had similar performances compared to CT in defining disease severity and predicting mortality, with the potential role of reducing the overload of CT facilities during the peak phases [19]. Attempts of providing quantitative information from CXR dates back at least two decades.Nevertheless, this topic found renewed interest, and several score systems have been tested in COVID-19 patients. One approach consists of a manual quantification of opacified areas, expressed as total of the lung surface [20 &&]. However, this approach is more time-consuming and less efficient compared to scoring systems such as the radiographic assessment of lung edema (RALE) [20 &&] score and Brixia score [21].Overall, while affected by several limitations, CXR still have a role in evaluating the respiratory function in critically ill patients.

在ICU中应用CXR已有数年的争论，有几个原因可能限制了其在重症患者中的诊断准确性。在 ICU 患者中，内部和外部医疗器械的使用是CXR的特定挑战，因为患者体位和其他因素限制了通过侧方扫描补充前后位投影的能力。一些协会建议在ICU患者中放弃每日CXR的做法，然而在过去几十年中，处方CXR的总数仅轻度减少。尽管CXR是重症患者中使用最多的影像学检查，但其仅与ICU住院期间约2%累积辐射量相关，即使CT检查仅占检查的12%，但累积辐射量几乎完全与CT检查时较高的每次检查剂量相关。在COVID-19大流行期间，CXR因易获得而广泛使用，可能减少疫情高峰期CT检查的超负荷，与CT相比，当使用视觉评估和评分时两者在定义疾病严重程度和预测死亡率方面相似。尽管至少二十年前就尝试从CXR中获取定量信息，但这一话题还是引起了新的兴趣，并在COVID-19患者中测试了几个评分系统。一种评分方法包括手动测量不透明区域，将其表示为肺表面的总面积。然而，与肺水肿影像学评估(RALE)评分和Brixia评分等评分系统相比，这种方法更耗时，效率更低。总体而言，虽有某些局限性，CXR仍具有评价重症患者呼吸功能的作用。
