合成磁共振成像在肿瘤诊断中的应用价值

Review of the application of synthetic magnetic resonance imaging in tumor diagnosis

合成磁共振成像(SyMRI)是一种全新的定量磁共振技术,一次扫描即可得到多种对比度加权图像,同时可量化组织的弛豫时间和质子密度。近年来,不断有关于SyMRI在前列腺、乳腺、直肠等肿瘤诊断中的应用报道。该文简要介绍SyMRI的基本原理及优缺点,综述其在肿瘤诊断、鉴别诊断及预后评估中的应用价值,并展望SyMRI在肿瘤诊断中的进一步广泛应用。

Synthetic magnetic resonance imaging(SyMRI)is a new quantitative magnetic resonance technique which can obtain multiple contrast-weighted images in a single scan and simultaneously quantify tissue relaxation time and proton density.In recent years,there have been continuous reports on the application of SyMRI in the diagnosis of prostate,breast,rectal and other tumors.This paper briefly introduces the basic principles,advantages and disadvantages of SyMRI,reviews its application value in tumor diagnosis,differential diagnosis and prognosis evaluation,and makes an outlook for the further extensive application of this technology in the future.
