Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Optimization-inspired deep unfolding correction-distillation network for CS-MRI reconstruction
优化启发 CS-MRI 重建深度展开 校正-蒸馏网络
2023/4/27
In this talk, we discuss a unifying deep unfolding multi-sampling-ratio interpretable CS-MRI framework. The combined approach offers more generalizability than the existing deep-learning-based CS-MRI ...
中国科学院高能物理研究所专利：一种用于MRI超导磁体可拨引线的接头结构
2023年1月6日，中国科学院精密测量科学与技术创新研究院研究员周欣研究团队设计构建了一种双模态分子探针氟化硝基Cy7，实现了活体肺癌中硝基还原酶的19F 磁共振和近红外荧光精准成像。相关研究成果发表在《德国应用化学》（Angew. Chem. Int. Ed.）上，并被遴选为本期的VIP（Very Important Paper）。
MRI联合超声检查与乳腺癌p53表达的相关性研究
磁共振成像 超声 乳腺癌 p53
2020/10/16
探讨乳腺癌组织p53表达与MRI及彩色多普勒超声征象的相关性。 方法 回顾性分析53例乳腺癌患者术前MRI及彩色多普勒超声征象，包括MRI乳腺背景实质强化（BPE）、病灶环形强化、TIC、周围血管征（AVS）以及超声Adler血供分型。采用免疫组化法分析乳腺癌p53表达情况。
超声与MRI诊断乳腺癌及不同病理分型影像特点分析
