肺结节CT随访中的生长特性评估

Computed tomography (CT) follow-up of indeterminate pulmonary nodules and the quantification of growth characteristics are the commonly adopted strategy in clinical setting. The volume/mass doubling time can be used to quantify the growth velocity based on exponential growth model. Therefore, we reviewed the followed aspects on growth evaluation of pulmonary nodules on chest CT, including the growth model of lung cancer, the methods used for nodule growth quantification and the growth characteristics of different types of pulmonary nodules.
