概括
使用MRI序列的深度学习模型有效预测P53突变肝细胞癌 (HCC). 综合模型整合了动脉阶段 (AP),门静脉阶段 (VP) 和T2加权成像 (T2WI),在识别这种侵袭性癌症变体方面显示出高准确性.
科学领域:
- 放射学和医学成像学 医学成像学
- 人工智能在医学中的应用
- 在瘤学瘤学.
背景情况:
- 发生P53突变的肝细胞癌 (HCC) 具有攻击性,与血管内皮生长因子 (VEGF) 和微血管密度增加有关.
- 预测HCC中P53突变状态对于向治疗和改善患者结果至关重要.
研究的目的:
- 开发和评估一个深度学习模型,利用MRI数据进行P53突变HCC的非侵入性预测.
- 为了比较单个MRI序列与组合序列在预测P53突变状态中的性能.
主要方法:
- 对312名病理确诊的HCC患者进行了回顾性分析,这些患者接受了加多增强的MRI.
- 基于EfficientNetV2的深度学习模型的开发,使用动脉相 (AP),门静脉相 (VP),T2加权成像 (T2WI) 和肝胆相 (HBP) 序列.
- 使用AUC,精度,灵敏度,特异性,精度和F1评分评估模型性能,与AUC比较的Delong测试进行比较.
主要成果:

02:43Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
