合成MRI(synthetic MRI,SyMRI)是一种日渐成熟的定量磁共振成像技术,能在短时间扫描内获得多种对比加权图像重建,可以直接获得反映组织生物物理特性的定量参数.该技术所获得的纵向弛豫时间T1、横向弛豫时间T2和质子密度(proton density,PD)在乳腺良恶性鉴别诊断、分子分型评估、组织学分级预测及预后评价发挥重要价值,现临床实践越来越广泛.本文就SyMRI技术原理及其在乳腺疾病中的研究进展及前景展开综述,期望能够帮助影像医师更全面地了解乳腺癌相关影像表现,为临床诊疗提供客观、精准的影像学信息.
Clinical application and progress of synthetic MRI in breast cancer
Synthetic MRI(SyMRI)is an increasingly mature quantitative magnetic resonance imaging technology,which can obtain a variety of contrast weighted image reconstruction in a short scan,and can directly obtain quantitative parameters reflecting the biophysical properties of tissues.The Tl,T2 and proton density(PD)values obtained by this technique play an important role in the differential diagnosis of benign and malignant breast,molecular typing evaluation,histological grading prediction and prognosis evaluation,and are now more and more widely practiced in clinical practice.This paper reviews the principle of SyMRI technology and the research progress and prospects in breast diseases,hoping to help radiologists to have a more comprehensive understanding of breast cancer-related image manifestations and provide objective and accurate imaging information for clinical diagnosis and treatment.
