In recent years, the detection rate of early lung cancer with microscopic lesions such as ground-glass nodules and sub-centimeter nodules (≤1 cm) has been significantly higher. For such lesions, early surgical intervention can effectively prolong the survival time of patients. But in the actual operation of these small lesions difficult to detect, which brought great difficulties to surgery. At present, clinically for such small lesions, usually in the preoperative CT-guided puncture positioning based on the implementation of surgical resection. This method of location there are trauma, complications and other shortcomings, so how to more precise positioning and labeling of lung lesions is a clinical problem to be solved urgently. In this paper, the localization and localization of lung lesions in recent years are reviewed, and the advantages and disadvantages of various methods and materials are summarized and analyzed.
