概括
此摘要是机器生成的。

这项研究开发了一个深度学习模型,使用MRI扫描来预测质母细胞瘤患者的伪进展与瘤进展. 该模型准确预测治疗反应和潜在瘤生长,有助于预后.

科学领域:

  • 神经成像
  • 医学的人工智能
  • 癌症学

背景情况:

  • 对质母细胞瘤 (GBM) 患者的治疗和预后来说,准确预测质母细胞瘤 (PsP) 与瘤进展 (TuP) 是至关重要的.
  • 使用常规成像方法将PsP与TuP区分开来是一项挑战.

研究的目的:

  • 开发和验证深度学习 (DL) 预后模型,用于预测 GBM 患者的 PsP 与 TuP.
  • 利用术前和术后对比度增强的T1加权 (CET1) 磁共振成像 (MRI) 来提高预测准确度.

主要方法:

  • 一个视力转换器 (ViT) DL模型从110名GBM患者的手术前和后的CET1MRI扫描中训练了专家细分的瘤区域.
  • 对比分析包括主流卷积神经网络 (CNN) 模型,通过PCA和LASSO回归进行特征选择.
  • 综合多模式方法将DL特征与临床特征集成,以进行全面的预测.

主要成果:

  • 使用手术前和手术后图像的CET1- ViT模型实现了高性能 (AUC高达95. 5%的训练,95. 2%的验证).
  • 在预测PsP与TuP方面,ViT模型显著优于标准CNN架构.
  • 多模式模型显示出优异的预测能力,AUC达到98.6% (训练) 和99.3% (验证).

Tumor Progression

6.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
