编辑推荐： 本研究针对胶质母细胞瘤 (GBM)患者放化疗 (RCT)后真性进展 (PD)与假性进展 (PsP)的临床鉴别难题，创新性采用Golden Angle Radial Sparse Parallel动态增强磁共振 (GRASP DCE-MRI)联合动态磁敏感对比 (DSC-MRI)技术，通过83例患者的多参数分析发现：联合Ktrans 、Ve 、Vp 和rCBV参数可将早期鉴别准确率 ...

基于以上背景，近期一项发表在 Advanced Science杂志的研究基于动态对比增强MRI（DCE-MRI）构建了ViT深度学习模型，旨在实现HER2状态的无创区分，并通过 ...

挑战与展望 尽管DCE-MRI标准化采集协议（如扫描时间分辨率>15秒）和人工智能辅助分析（如像素级药代动力学建模）已取得进展，但设备异质性和运动伪影仍是推广瓶颈。 未来研究需聚焦多中心验证及成本效益分析，以确立其在关节炎诊疗路径中的核心地位。

Four dose levels were administered (5 mg/m 2, 8.4 mg/m 2, 16.5 mg/m 2, and 27.5 mg/m 2. Results: 10 patients underwent DCE-MRI scans and eight patients with 44 total evaluable lesions had available ...

Methods: Since 2005, 50 subjects with NM-HNSCC (minimum 1 cm) treated with concurrent platinum based chemoradiotherapy were prospectively enrolled and evaluated with DCE-MRI to evalute nodal perfusion ...

TRIPLE-NEGATIVE breast cancer (TNBC) remains one of the most aggressive subtypes of breast cancer, with limited targeted treatment options. Neoadjuvant chemoimmunotherapy (NACI) has improved rates of ...

DCE-MRI uses a blood-borne contrast agent to capture before and after images of the brain’s vasculature. It “ possesses an unparalleled capacity to quantitatively measure not only perfusion but also ...
