食管癌多层螺旋CT灌注成像研究现状

Research Status Quo of Perfusion Imaging with Multidetector Row Computed Tomography on Esophageal Cancer

食管癌是常见的恶性肿瘤之一。多层螺旋CT灌注成像作为一种无创手段,可以在活体状态下评价其微循环。近年来,CT灌注成像在食管癌的微循环评价、放化疗的疗效判断方面取得进展。本文着重综述多层螺旋CT灌注成像技术在食管癌中的应用研究现状。

Esophageal cancer is one of frequent malignant tumors worldwide.As a noninvasive technique,computed tomography（CT） perfusion imaging could be valuable to assess the microcirculation of esophageal cancer in vivo.Recently,multidetector row CT（MDCT） perfusion imaging has sparked new interest in the assessment of the microcirculation of esophageal cancer,and therapeutic effects of chemoradiotherapy on this tumor.In this paper,we reviewed the status quo of perfusion imaging with MDCT on esophageal cancer.
