| With the worsening air pollution and deteriorating people’s living environment, the incidence of respiratory diseases is persistently higher, the most concern is the incidence of lung cancer which has become the leading cause of cancer mortality in China. However the symptoms of early-stage pulmonary malignant tumor are not obvious and the health consciousness is bad, when they have clinical features, they are usually diagnosed at an advanced stage with losing valuable operative chances. Five-year survival rate of lung cancer is around 15%, which is a very important factor to lead to the higher mortality. In the final analysis, the reason is the low detectable rate of early-stage pulmonary adenocarcinoma. With the progress of science technology and the widespread application of high-resolution CT(HRCT) and positron emission tomography/computed tomography(PET/CT), more and more solitary pulmonary ground-glass opacity(GGO) have been identified, which attract much interest by patients and clinicians. GGO is the non-specific Imaging of early-stage pulmonary cancer, definite diagnosis and prompt surgery usually achieve satisfactory outcome, but operation is the invasive treatment, benign lesion or small size of GGO can treat with conservative treatment or follow up closely, and once considered malignance, timely surgical resection. In order to let people know more about solitary pulmonary GGO, improve their health awareness, improve detection rate of early lung cancer, guide the treatment of GGO, this article reviewed the progress in imaging diagnosis, localization, treatment and follow-up. |
