For solid nodules are only imaging descriptions, not disease diagnosis, imaging purely solid nodules, and there is no way to completely determine the benign and malignant. For the gold standard for the nature of nodules, the actual pathology, generally solid nodules >1cm or more, tend to have a relatively high likelihood of malignancy, but if calcified components are present in the lesion, solid nodules are more likely to be benign, especially in tuberculosis, which is often prone to calcified components. If subcentimeter solid lesions, that is, solid nodules less than 1 cm, the percentage of benign is higher, about 60% are benign. Some people with normal structures, such as lymph nodes, tend to show up as subcentimeter solid nodules on imaging.
