In the case of febrile neutropenia, a chest X-ray most often does not detect pneumonia and this may be related to the low sensitivity of this technique since high-resolution computed tomography (CT) has been shown to be suggestive of pneumonia in the majority of the cases when fever persists for more than 48 h. In such cases, early documentation of pneumonia is often possible. The pattern of pulmonary infiltrates on chest radiograph and CT scan can only be considered as indicative and confirmation of non-infectious or infectious processes is better achieved by bronchoalveolar lavage combined with transbronchial biopsy provided there is no contraindication. The results of the CT scan may also help to determine the site of sampling.
在发热性中性粒细胞减少症的情况下，胸部X光检查大多无法检测到肺炎，这可能与该技术的低敏感性有关，因为当发热持续超过48小时时，高分辨率计算机断层扫描（CT）在大多数病例中已显示提示肺炎。在这种情况下，肺炎的早期记录通常是可能的。胸部X光片和CT扫描上的肺部浸润模式只能作为指示性的，只有在没有禁忌症的情况下，通过支气管肺泡灌洗联合经支气管活检才能更好地确诊非感染性或感染性过程。CT扫描结果也可能有助于确定采样部位。
