摘要
弥散加权成像技术（DWI）作为一种无辐射、无创伤的检查手段，在食管癌诊断及分期方面已表现出独特优势。其表观弥散系数的测定对食管癌的疗效评估也显示出较高的临床应用价值。应用DWI与定位计算机体层成像（CT）图像融合制定治疗计划，既可以发挥CT在解剖结构方面的优势，又可以发挥DWI在食管癌临床分期、诊断方面的优势，有望使靶区勾画准确性提高。
Magnetic resonance imaging diffusion weighted imaging （DWI）as a non-radiation and noninvasive examination method, has shown its unique advantages in diagnosis and staging of esophageal cancer. The ADC value has demonstrated clinical application value in the therapeutic assessment. Application of DWI and CT image fusion could combine the advantages of CT in anatomical structure and the advantages of MRI in clinical stages and diagnosis. The accuracy of target area sketching would be improved.
