摘要:

创伤性脑损伤可引起颅内出血(ICH)。如果没有在时间敏感的手术中准确诊断和治疗,ICH可能导致残疾或死亡。目前诊断ICH的临床方案是由放射科医生检查计算机断层扫描(CT)扫描,以检测ICH并定位其区域。然而,这个过程在很大程度上依赖于有经验的放射科医生的可用性。在本文中,我们设计了一个研究方案,收集了82例创伤性脑损伤患者的CT扫描数据集。之后,由两名放射科医生一致决定在每个切片中手动划定ICH区域。最近,全卷积网络(FCN)在医学图像分割中取得了成功。我们开发了一种称为U-Net的深度FCN,以完全自动化的方式从CT扫描中分割ICH区域。基于5倍交叉验证,该方法实现了ICH分割的Dice系数为0.31。该数据集可在PhysioNet存储库在线公开获取,以供未来分析和比较。

英文摘要:

Traumatic brain injuries could cause intracranial hemorrhage (ICH). ICH could lead to disability or death if it is not accurately diagnosed and treated in a time-sensitive procedure. The current clinical protocol to diagnose ICH is examining Computerized Tomography (CT) scans by radiologists to detect ICH and localize its regions. However, this process relies heavily on the availability of an experienced radiologist. In this paper, we designed a study protocol to collect a dataset of 82 CT scans of subjects with traumatic brain injury. Later, the ICH regions were manually delineated in each slice by a consensus decision of two radiologists. Recently, fully convolutional networks (FCN) have shown to be successful in medical image segmentation. We developed a deep FCN, called U-Net, to segment the ICH regions from the CT scans in a fully automated manner. The method achieved a Dice coefficient of 0.31 for the ICH segmentation based on 5-fold cross-validation. The dataset is publicly available online at PhysioNet repository for future analysis and comparison.
