弥散加权成像在直肠癌诊断中的应用价值

Application of Diffusion Weighted Imaging in Rectal Cancer Diagnosis

目前磁共振成像已作为直肠癌诊断的主要方法,而弥散加权成像作为一种新的磁共振功能成像技术,提高了病变检出敏感性并提供机体功能改变信息,近20年来,其在临床中的应用范围不断扩大,应用价值明显提升。本文主要从诊断、分期及术前放化疗效果评估等方面评价弥散加权成像在直肠癌中的应用价值。

Magnetic resonance imaging has became the major method for rectal cancer diagnosis. As a novel magnetic resonance functional imaging technique, diffusion-weighted imaging has improved the lesion detection sensitivity and provided more information on changes nessed the increasing application of this technique in clinical in body functions. The past two decades have witpractices. This article summarizes the application of diffusion weighted imaging in rectal cancer diagnosis.
