[Diagnosis and management of solitary pulmonary nodules]

Currently in China, the incidence and death rate of lung cancer with low five-year survival rates has ranked the first position among all cancers. Early detection of lung cancer and early treatment are of great importance. However, patients with early satge lung cancer always do not present with any synptoms or signs, only to demonstrate solitary pulmonary nodules (SPNs) in radiology findings. So it is very critical to improve the ability to identify the SPNs, and with the development of sorts of diagnostic modalities, the accuracy in the evaluation of the SPNs has imporved greatly.
