Lateral radiograph
Computed tomography
Follow-up radiograph


Observation of discrete abnormal densities within the lung fields are described as nodules. When the density is similar to that of the ribs, they can be presumed to be calcified. Confirmation of the presence of calcium can be obtained quantitatively from computed tomography which may, with its greater quantitative soft tissue sensitivity, reveal other inapparent parenchymal densities.
