Abstract:
The gold standard evaluation criteria of radiotherapeutic effect at the present time is the three-level classification of X-ray barium meal.However,this method has certain limitations.Morphological changes in esophagus wall and metastases after radiotherapy can be observed on computed tomography scanning.A positron emission tomography scan is a sensitive imaging test to observe the metabolic activity in pathologic cells and tissues.And diffusion-weighted magnetic resonance imaging could provide the esophageal tumor necrosis information after radiotherapy by observing the changes of water molecular diffusion.With the development of medical imaging techniques,using various means in a comprehensive way to evaluate radiotherapeutic effect for esophageal carcinoma patients may become a trend.
