求翻译：In this paper, we will discuss the initial evaluation of suspected RA-ILD focusing on screening algorithms and radiologic features of the disease. However, screening and diagnosis of RA-ILD is only one aspect of care. Once the presence of RA-ILD is certain, the challenge for clinicians comes in distinguishing an exacerbation of RA-ILD from infection, drug toxicity, or a host of other comorbid disease entities. We will explore a practical approach to the workup and treatment of a clinical deterioration in the established RA-ILD patient, and the following case history will serve as a framework for this discussion highlighting some of the inherent challenges.是什么意思？
