CLAIRE-DSA: Fluoroscopic Image Classification for Quality Assurance of Computer Vision Pipelines in Acute Ischemic Stroke

  • 基于ResNet模型,分类1758张造影图像的9种关键质量属性。
  • 过滤低质图像后,病灶分割成功率从42%提升至69%,显著提高。
  • 适合临床与科研中对血管造影图像进行自动化质检和流程优化。

计算机视觉模型可用于急性缺血性卒中机械取栓术(MT)的辅助决策,但图像质量差常导致性能下降。本文提出CLAIRE-DSA,一种基于深度学习的框架,用于对MT过程中获取的最小强度投影(MinIP)图像进行关键属性分类,支持下游质量控制与流程优化。该模型采用预训练的ResNet主干网络,在包含1,758张荧光造影MinIP图像的标注数据集上微调,可预测包括对比剂存在、投影角度、运动伪影严重程度等9类图像属性。各标签的受试者工作特征曲线下面积(ROC-AUC)在0.91至0.98之间,精确率介于0.70至1.00。通过筛选低质量图像并对比过滤前后数据集的分割表现,验证了其有效性:分割成功率从42%提升至69%(p < 0.001)。CLAIRE-DSA展现出作为自动化工具在急性缺血性卒中患者数字减影血管造影(DSA)序列中准确分类图像属性的潜力,支持临床与研究中的图像标注与质量控制。源代码见https://gitlab.com/icai-stroke-lab/wp3_neurointerventional_ai/claire-dsa。

原文摘要 · Abstract (English)

Computer vision models can be used to assist during mechanical thrombectomy (MT) for acute ischemic stroke (AIS), but poor image quality often degrades performance. This work presents CLAIRE-DSA, a deep learning--based framework designed to categorize key image properties in minimum intensity projections (MinIPs) acquired during MT for AIS, supporting downstream quality control and workflow optimization. CLAIRE-DSA uses pre-trained ResNet backbone models, fine-tuned to predict nine image properties (e.g., presence of contrast, projection angle, motion artefact severity). Separate classifiers were trained on an annotated dataset containing $1,758$ fluoroscopic MinIPs. The model achieved excellent performance on all labels, with ROC-AUC ranging from $0.91$ to $0.98$, and precision ranging from $0.70$ to $1.00$. The ability of CLAIRE-DSA to identify suitable images was evaluated on a segmentation task by filtering poor quality images and comparing segmentation performance on filtered and unfiltered datasets. Segmentation success rate increased from $42%$ to $69%$, $p < 0.001$. CLAIRE-DSA demonstrates strong potential as an automated tool for accurately classifying image properties in DSA series of acute ischemic stroke patients, supporting image annotation and quality control in clinical and research applications.
