磁共振成像（Magnetic Resonance Imaging, MRI）是现今临床医学诊断的重要手段之一，但如何提高成像技术、应用场景等成为该领域近来的热门研究问题。

随着人工智能及机器学习的发展，深度学习方法被应用于医学图像处理中，同时也使磁共振成像在新的时代背景下有了新的发展动力。

近日，上海科技大学图书信息中心发布了一篇题为《深度学习时代下的磁共振成像》的研究报告。

该报告检索2013年至今近十年发表的SCI期刊论文作为分析对象，考察该领域的研究发展态势和变化趋势。

该报告根据磁共振成像及深度学习的语义特征、相关的关键词，设计了检索式：主题=("Magnetic Resonance Imag*" OR MRI) AND "deep learn*"，时间范围为2013-2022年，同时限制文献类型为Article。

报告的数据源来自Web of Science数据库中的SCI索引集、InCites数据库。

其中，在Web of Science数据库SCI索引集中，共检索到2013-2022年间发表的该主题共计3254篇研究论文。

论文数量进入爆发增长期

深度学习时代下的磁共振成像领域在2013-2021间每年的SCI论文产出数量是逐年递增的。

2013-2015年文章数量还处于零星增长阶段，2016-2017年发文量增长明显，但仍相对为低位，而从2018年起的近五年里则呈现了爆发增长的趋势，并且增长率越来越高。

2022年度，截至检索日期（2022-06-27）共发文674篇。
