摘要:

头部非增强计算机断层扫描(NCCT)因其广泛的可用性和快速性,仍是首选的初级成像方式。然而,当前对头部NCCT扫描中异常脑组织进行人工标注的标准存在显著缺点,例如缺乏截断值标准化和退行性识别。近年来,基于深度学习的计算机辅助诊断(CAD)模型在多学科领域的进展为神经医学影像创造了巨大机遇。此前已有大量文献报道了在不同成像模态上自动识别脑组织的研究。然而,由于图像纹理、体积大小和扫描质量的可变性,确定颅内出血(ICH)和梗死可能具有挑战性。这项回顾性验证研究评估了一种基于深度学习(DL)的算法,该算法从头部NCCT扫描中识别ICH和梗死。头部NCCT扫描数据集连续收集自印度多个诊断影像中心。该研究展示了此类基于DL的软件在大型医疗机构常规工作流程中引入的潜力和局限性。

英文摘要:

Head Non-contrast computed tomography (NCCT) scan remain the preferred primary imaging modality due to their widespread availability and speed. However, the current standard for manual annotations of abnormal brain tissue on head NCCT scans involves significant disadvantages like lack of cutoff standardization and degeneration identification. The recent advancement of deep learning-based computer-aided diagnostic (CAD) models in the multidisciplinary domain has created vast opportunities in neurological medical imaging. Significant literature has been published earlier in the automated identification of brain tissue on different imaging modalities. However, determining Intracranial hemorrhage (ICH) and infarct can be challenging due to image texture, volume size, and scan quality variability. This retrospective validation study evaluated a DL-based algorithm identifying ICH and infarct from head-NCCT scans. The head-NCCT scans dataset was collected consecutively from multiple diagnostic imaging centers across India. The study exhibits the potential and limitations of such DL-based software for introduction in routine workflow in extensive healthcare facilities.
