| 摘 要： | 目的:总结国内外CT灌注技术及其在食管癌中的应用进展。方法:应用Medline和CNKI期刊全文数据库系统,以"食管癌、计算机体层成像、灌注"为关键词,检索1991-01—2010-01的相关文献,共检索到英文文献61篇和中文文献11篇。纳入标准:1)CT灌注技术的理论基础;2)食管癌灌注参数的意义;3)CT灌注在食管癌诊断、治疗中的价值。根据纳入标准分析24篇文献。结果:1)食管癌CT灌注参数血容量(BV)和峰值到达时间(TTP)与食管癌微循环情况有良好相关性;2)放疗前后的食管癌CT灌注参数毛细血管通透性(PS)、强化峰值(PEI)有显著差异;3)食管癌患者对放化疗的敏感性及治疗效果与CT灌注参数显著相关,对放化疗敏感的患者其灌注参数BV、血流量(BF)高于不敏感者,而MTT短于不敏感者;4)CT灌注可以对局部和远处转移的食管癌进行检测和分期。结论:CT灌注技术可以评价血管生成情况,对食管癌具有诊断价值;也可以评价和预测放化疗疗效,辅助食管癌治疗;同时,CT灌注还是食管癌分期的一种新方法。
