磁共振扩散张量成像诊断前列腺癌的理论基础

前列腺癌是威胁老年男性健康的重要疾病,MRI目前被一致认为是前列腺疾病理想的检查方法。MR扩散张量成像(DTI)通过在多个方向施加扩散敏感梯度而测量水分子扩散程度的方向性,从而提供组织微观结构的信息;可以弥补常规磁共振诊断前列腺疾病的不足。该文对DTI诊断前列腺癌理论基础进行综述。

Prostate cancer:theoretical base of MR diffusion tensor imaging study

Prostate cancer is a major disease ,which threatens the health of older men, magnetic resonance imaging is currently being agreed as the ideal method of diagnosis of prostate disease. Magnetic resonance diffusion tensor imaging by applying diffusion sensitizing gradient in multiple directions to measure the degree of water molecules’ diffusion directionality, provides information of the organization of the microstructure;It can compensate for the lack of conventional MRI diagnosis of prostate disease. This article aims to review the theoretical basis of magnetic resonance diffusion tensor imaging diagnosis of prostate cancer .
