宝石能谱CT成像在肝转移瘤诊断及疗效评价中的应用

Application of Gemstone Spectral CT Imaging and in Diagnosis and Efficacy Evaluation of Hepatic Metastasis

肝脏是转移瘤的好发部位之一,有效监测及早期评价肿瘤治疗的效果对肝转移瘤患者至关重要。传统的影像学检查局限于形态学或血供情况,难以从定性、定量等层次进行分析,宝石能谱CT实现了单能量、低kev图像,从而提高了组织间的对比度,优化了图像质量,结合碘基图像的定量分析能够准确全面反映病灶的解剖及血供情况,同时显示功能信息,还可对不同组织来源的肝转移瘤作出初步判断。故能谱CT能够为监测和早期评价肝转移瘤治疗疗效提供指导。

Liver is one of the predilection sites of metastasis, and effective monitoring and early assess- ment of treatment efficacy is very important for patients with hepatic metastasis. The traditional imaging inspection method is limited to the morphology or blood supply,hard to realize the qualitative and quantitative analysis ,while gemstone spectral imaging （GSI）technology can improve tissue contrast, optimize the image quality by the single energy imaging, low energy image and achieve image observation and quantitative analy- sis by the iodine-based image, so this technology obviously improve the detection rate of lesions changes by treatment, roundly reflect the situation of lesions, and concurrently display anatomical and functional informa- tion. Therefore, GSI can provide guidance for early monitoring and evaluation of the treatment effect of hepatic metastasis.
