一个新的多发性硬化症 (MS) 脑预测疾病持续时间差距 (DD差距) 模型显示对MS病变和脑缩的敏感性. 这种MS特定的生物标志物补充了大脑年龄差距分析,解释了身体残疾的进展.
科学领域:
- 神经成像是一种神经成像.
- 人工智能在医学中的应用
- 神经学 神经学
背景情况:
- 区分正常的大脑衰老与多发性硬化症 (MS) 中的神经退行是至关重要的.
- 大脑年龄范式可能无法完全捕捉到MS特定的病理变化.
- 开发特定疾病的生物标志物对于了解多发性硬化症的进展至关重要.
研究的目的:
- 研究一种特定于疾病的模型,以补充MS患者的大脑年龄差距 (BAG).
- 开发和验证脑预测疾病持续时间差距 (DD差距) 作为MS特异性脑损伤的衡量标准.
- 评估DD差距,BAG和身体残疾之间的关系.
主要方法:
- 追溯分析3D T1加权脑MRI扫描从一个大多中心队列的MS (PwMS) 患者.
- 训练3DDenseNet模型来预测疾病持续时间 (DD),并使用DeepBrainNet进行年龄预测.
- 对DD差距的验证与扩展残疾状况量表 (EDSS) 横截面和纵向分数的验证.
主要成果:
- 与大脑年龄模型不同,DD差距模型显示对MS病变和大脑缩的敏感性.
- DD差距显著解释了身体残疾 (EDSS) 的变化,无论是横截面还是纵向.
- 与单独的BAG相比,DD差距在解释残疾恶化方面提供了增量价值.
结论:
- 大脑预测的DD差距是一个敏感的,MS特定的生物标志物,反映了疾病的严重程度和进展.
- 这种DD差距测量方法补充了大脑年龄范式,用于评估MS患者的身体残疾.
- 该DD差距有可能用于监测MS疾病严重程度和进展的临床应用.
