| Research Abstract |
In this study, we studied the image parameters to predict the therapeutic effect of radiotherapy/chemoradiotherapy for esophageal cancer. We had done research on the response evaluation using the barium swallow as a preliminary study, and the result was that the change in the percent esohpageal stenosis before and after treatment was correlated with the therapeutic response. Our main study was the response evaluation using the MRI including diffusion-weighted images. Of the 31 cases registered cases, treatment response were evaluated in 20 cases. There was no relationship between the treatment response and the MRI findings before and after treatment in the 10 cases that underwent the definitive chemoradiotherapy. Apparent diffusion coefficient (ADC) values and change of them were significantly associated with treatent response in the 10 cases that underwent preoperative chemoratiotherapy.
