Development of a computer-aided design system for detection of acute cerebral infarction in emergency medicine using the multi-energy method based on MDCT

在日本，脑血管疾病是导致死亡的第三位原因，也是卧床不起患者的第一位原因。本研究旨在开发一种基于图像的脑梗塞诊断方法，这是近年来一直在认真考虑的问题。回顾了用X射线计算机断层扫描(CT)检测急性脑梗塞所需的条件，提出了一种用于脑梗塞可视化的图像处理算法。评估了颅骨对这种可视化的影响，并检查了双能量图像的使用。结果表明，在急性脑梗塞的早期阶段发现急性脑梗塞的可能性是可能的，而急性脑梗塞是X线CT难以发现的。

In Japan, cerebrovascular disease is the third cause of death and the first cause of bedridden patients. This study aimed to develop a method for image-based diagnosis of cerebral infarction, which has been under serious consideration in recent years. The conditions required to detect acute cerebral infarction by X-ray computed tomography (CT) were reviewed, and an image-processing algorithm for infarction visualization was developed. The effect of the cranium on this visualization was evaluated and the use of dual-energy images was examined. The results demonstrate the possibility of detecting acute cerebral infarction at its early stage, which is difficult to visualize by X-ray CT.
