DSA作为血管造影的主要设备,是肝癌诊断和鉴别诊断的常用方法之一,DSA时间密度曲线分析,对于鉴别原发性肝癌和转移性肝癌具有重要意义。由于目前国内外普遍使用的DSA设备无法进行密度定量分析,DSA图像诊断的定量分析受到很大限制。笔者应用Photoshop图像处理软件对肝癌DSA时间
As the main equipment of angiography, DSA is one of the commonly used methods for the diagnosis and differential diagnosis of liver cancer. DSA time-density curve analysis is of great significance for the identification of primary liver cancer and metastatic liver cancer. Due to the fact that DSA equipment commonly used at home and abroad can not perform density quantitative analysis, the quantitative analysis of DSA image diagnosis is greatly limited. I applied Photoshop image processing software on liver cancer DSA time
