Incidental findings of solitary pulmonary nodules on computed tomographic pulmonary angiography: a hidden workload.

摘要

Computed tomographic pulmonary angiograms (CTPAs) are increasingly used as the primary radiological investigation in suspected pulmonary emboli. Pulmonary nodules measuring 1-2 mm can now be detected on CT scanning. A small number of these turn out to be malignant and guidelines for follow-up have been suggested. The follow-up of these patients often requires further CT scans and places demands on chest physicians and radiologists.
