ACR Appropriateness Criteria® screening for pulmonary metastases.

Screening for pulmonary metastatic disease is an important step for staging a patient with a known or recently discovered malignancy. Here we present our recommendations for screening for metastatic disease based on recommendations from the literature and experiences of pulmonary radiologists. In short, chest computed tomographic (CT) screening is the most appropriate tool for evaluation of pulmonary metastasis in the majority of cases. Chest computed tomographic screening is also recommended for follow-up and to determine response to therapy. Other modalities such as chest radiography, magnetic resonance imaging, and scintigraphy will also be discussed.
