近年来肺结节的检测率明显提高,尽早确定肺结节的良恶性对于提高早期肺癌的治愈率意义重大。肺结节体积测量技术可以准确监测结节的体积变化和生长情况,进而可判断良恶性。介绍肺结节体积测量技术的基本原理、测量过程的可重复性、临床应用以及存在的一些问题。 In recent years, the detection rate of pulmonary nodules was significantly improved, as soon as possible to determine the benign and malignant lung nodules for improving the cure rate of early lung cancer is of great significance. Pulmonary nodule volume measurement technology can accurately monitor the volume changes and growth of nodules, which can be judged benign and malignant. Introduce the basic principle of pulmonary nodule volume measurement technology, the repeatability of the measurement process, clinical application and some existing problems.
