单纯采用形态学方法对肺小结节做出准确定性诊断较为困难。肿瘤倍增时间是反映肿瘤生长特征的重要指针,计算肺小结节的肿瘤倍增时间,对其定性诊断有重要价值。近年来,采用高分辨率CT(High resolution CT,HRCT)或多层螺旋CT(Multi-detectorrow CT,MDCT)测定肿瘤倍增时间的研究取得了一些进展,本文着重就肺癌肿瘤倍增时间特点及其病理学基础作一综述。
It is more difficult to make exact qualitative diagnosis of pulmonary nodules by simple morphological methods. Tumor doubling time is an important indicator to reflect the characteristics of tumor growth. Calculating the tumor doubling time of pulmonary nodules is of great value to the qualitative diagnosis. In recent years, some progresses have been made in the study of tumor doubling time using High Resolution CT (HRCT) or Multi-detectorrow CT (MDCT). This article focuses on the characteristics of lung cancer doubling time and its disease The rationale for a comprehensive review.
