摘要
肾脏肿瘤的分型与鉴别关系到治疗方案的选择和预后。CT纹理分析是基于图像中像素或体素灰度级的分布和关系特点,对肿瘤的异质性进行客观定量的评估故能够弥补传统的图像视觉分析方法诊断的主观局限性。本文对CT纹理分析及其在肾脏肿瘤诊断中的应用和局限性等的研究进展进行综述。
The classification and differentiation of renal tumors are related to the choice of therapeutic modalities and prognosis of patients.CT texture analysis is an objective and quantitative assessment of tumor heterogeneity based on the distribution and relationship characteristics of pixel or voxel gray levels in images,which can make up for the subjective limitations of traditional image visual analysis methods for diagnosis.In this article,CT texture analysis and its application in the diagnosis of renal tumors are reviewed and the limitations are also discussed.
