Abstract
Pulmonary nodules less than 10 mm in length are often detected on computed tomography
(CT) scans after the examination is completed. No further imaging may be possible
and it would be useful to determine whether the nodule is sufficiently calcified to
be considered benign. We wanted to use the relationship between the true and apparent
nodule density on 10-mm CT sections to determine the true density of the nodule. An
understanding of the partial volume effect on 10-mm CT images of small pulmonary nodules
allowed us to identify accurately those which were diffusely calcified without having
to resort to obtaining additional 1-mm CT sections.
