- 适合临床辅助诊断,尤其适用于需要可解释性的医学场景
颅内出血(ICH)指脑内或脑周血管破裂导致的血液泄漏,若未能及时诊断和治疗,可能引发意识下降、永久神经损伤甚至死亡。本研究旨在检测是否存在ICH,并进一步判断硬膜下出血(SDH)类型,将其建模为两个独立的二分类问题。在共尺度卷积注意力(CCA)分类器架构基础上,新增两层:第一层从CT扫描不同切片中提取特征后,选取方差最高的50个成分作为关键特征,并利用自助森林算法评估其判别能力,剔除区分度不足的特征,构建可解释性AI模型;第二层引入基于不确定性的模糊积分算子,融合连续切片间的信息,考虑切片间的依赖关系,显著提升检测精度。
原文摘要 · Abstract (English)
Intracranial hemorrhage (ICH) refers to the leakage or accumulation of blood within the skull, which occurs due to the rupture of blood vessels in or around the brain. If this condition is not diagnosed in a timely manner and appropriately treated, it can lead to serious complications such as decreased consciousness, permanent neurological disabilities, or even death.The primary aim of this study is to detect the occurrence or non-occurrence of ICH, followed by determining the type of subdural hemorrhage (SDH). These tasks are framed as two separate binary classification problems. By adding two layers to the co-scale convolutional attention (CCA) classifier architecture, we introduce a novel approach for ICH detection. In the first layer, after extracting features from different slices of computed tomography (CT) scan images, we combine these features and select the 50 components that capture the highest variance in the data, considering them as informative features. We then assess the discriminative power of these features using the bootstrap forest algorithm, discarding those that lack sufficient discriminative ability between different classes. This algorithm explicitly determines the contribution of each feature to the final prediction, assisting us in developing an explainable AI model. The features feed into a boosting neural network as a latent feature space. In the second layer, we introduce a novel uncertainty-based fuzzy integral operator to fuse information from different CT scan slices. This operator, by accounting for the dependencies between consecutive slices, significantly improves detection accuracy.
