A number of studies have shown that high-resolution CT (HRCT) scanning may be helpful in the assessment of acute diffuse lung disease in immunocompromised patients. HRCT may demonstrate abnormalities when the radiograph is normal and may allow for a more confident diagnosis in patients with nonspecific radiographic findings. Because HRCT is superior in demonstrating the distribution and extent of parenchymal abnormalities, it is also helpful as a guide to the optimal type and site of lung biopsy. This article reviews the HRCT manifestations of the most common causes of acute diffuse lung disease in the immunocompromised host, including infection, drug-induced lung disease, pulmonary edema, and neoplasms.
多项研究表明，高分辨率CT（HRCT）扫描可能有助于评估免疫功能低下患者的急性弥漫性肺疾病。当X线胸片正常时，HRCT可能显示异常，并且对于具有非特异性X线表现的患者，它可能有助于做出更可靠的诊断。由于HRCT在显示实质异常的分布和范围方面更具优势，因此它也有助于指导肺活检的最佳类型和部位。本文综述了免疫功能低下宿主急性弥漫性肺疾病最常见病因的HRCT表现，包括感染、药物性肺疾病、肺水肿和肿瘤。
