摘要:

颅内出血(ICH)后的预后受影像和表格数据间复杂相互作用的共同影响。快速可靠的预后对于有效的患者分层和明智的治疗决策至关重要。本研究旨在通过学习预后与高度相关的临床及人口统计学变量之间共享的稳健特征表示,来增强基于影像的预后。我们的方法通过强化模型学习嵌入在影像中的有价值的预后数据,从而模拟临床决策。我们提出了一种3D多任务影像模型,用于预测预后、格拉斯哥昏迷量表(GCS)评分和年龄,从而提高准确性和可解释性。我们的方法优于当前最先进的基线影像模型,并且在仅使用CT扫描作为输入的情况下,在ICH预后方面表现出优于四位获得委员会认证的神经放射科医生的卓越性能。我们进一步通过可解释性显著性图验证了我们的模型。代码可在 https://github.com/MiriamCobo/MultitaskLearning_ICH_Prognosis.git 获取。

英文摘要:

Prognosis after intracranial hemorrhage (ICH) is influenced by a complex interplay between imaging and tabular data. Rapid and reliable prognosis are crucial for effective patient stratification and informed treatment decision-making. In this study, we aim to enhance image-based prognosis by learning a robust feature representation shared between prognosis and the clinical and demographic variables most highly correlated with it. Our approach mimics clinical decision-making by reinforcing the model to learn valuable prognostic data embedded in the image. We propose a 3D multi-task image model to predict prognosis, Glasgow Coma Scale and age, improving accuracy and interpretability. Our method outperforms current state-of-the-art baseline image models, and demonstrates superior performance in ICH prognosis compared to four board-certified neuroradiologists using only CT scans as input. We further validate our model with interpretability saliency maps. Code is available at https://github.com/MiriamCobo/MultitaskLearning_ICH_Prognosis.git.
