脑水肿的诊断主要依靠CT、MRI等传统监测技术，但传统技术往往不具备经济、实时动态、可床边监测的理想监测方式。目前，国内外研究较为热门的新型脑水肿监测设备层出不穷、各有千秋，及时通过这些新型无创监测技术对颅脑损伤患者脑水肿趋势和颅脑疾病高危人群的颅内压概况进行监测，可能会对专科医疗行为的决策起到关键辅助指导作用。因此，一种可靠、廉价且适用范围大的脑水肿监测技术已经成为科学研究者、临床工作人员和病患人群的迫切需求。本文围绕无创脑水肿监测技术的研究现状及展望作一综述。

The diagnosis of cerebral edema mainly relies on traditional monitoring techniques such as CT and MRI, but traditional techniques often do not have the ideal monitoring method of economy, real-time dynamic, and bedside monitoring. At present, there are an increasing number of new Brain edema monitoring devices that are popular at home and abroad. These new non-invasive monitoring technologies are used to monitor the situation of brain edema in patients with craniocerebral injury and the profile of intracranial pressure in high-risk populations with craniocerebral diseases. It may play a key role in assisting and guiding the decision-making of specialized medical behavior. Therefore, a reliable, inexpensive and widely applicable brain edema monitoring technology has become an urgent need for scientific researchers, clinical staff and patients. This article reviews the research status and prospect of noninvasive brain edema monitoring techniques.
