摘要

本文提出了一个新颖的框架,通过自动测量视神经鞘直径(ONSD)和眼球横径(ETD),从外伤患者的眼部超声图像预测升高的颅内压(ICP)。使用眼部超声波扫描测量视神经鞘直径是非侵入性的,与升高的 ICP 相关。然而,现有研究表明,仅凭ONSD值不足以说明ICP的情况。由于不同种族/原住民患者的 ONSD 值和 ETD 值可能会有所不同,因此有必要开发一种独立的全球生物标志物来预测 ICP 升高的情况。本研究通过开发自动测量 ONSD 和 ETD 值的算法,建立了预测 ICP 升高的自动化框架。研究证实,ONSD 和 ETD 比值 (OER) 是预测 ICP 的潜在生物标志物,不受种族和出身的影响。通过对从新德里 AIIMS 获取的 57 名创伤患者的数据进行统计分析,确定了 OER 临界值。通过确定合适的相关系数,计算出自动 OER,并与传统测量的 ICP 进行比较。结果发现,OER 与 ICP 存在明显的相关性(r = .81,p ≤ .01),而仅 ONSD 与 ICP 的相关性相对较小(r = .69,p = .004)。这些相关值表明,OER 是预测 ICP 的更好参数。此外,本研究还发现 OER 的阈值为 0.21,可用于预测升高的 ICP 条件。OER 和相应 ICP 的散点图和热图分析显示,OER ≥ 0.21 的患者的 ICP 在 17 至 35 mm Hg 之间。在本研究工作的可用数据中,OER 在 0.17 至 0.35 之间。

A Novel Method for Prediction of Raised Intracranial Pressure Through Automated ONSD and ETD Ratio Measurement From Ocular Ultrasound.

The paper presents a novel framework for the prediction of the raised Intracranial Pressure (ICP) from ocular ultrasound images of traumatic patients through automated measurement of Optic Nerve Sheath Diameter (ONSD) and Eyeball Transverse Diameter (ETD). The measurement of ONSD using an ocular ultrasound scan is non-invasive and correlates with the raised ICP. However, the existing studies suggested that the ONSD value alone is insufficient to indicate the ICP condition. Since the ONSD and ETD values may vary among patients belonging to different ethnicity/origins, there is a need for developing an independent global biomarker for predicting raised ICP condition. The proposed work develops an automated framework for the prediction of raised ICP by developing algorithms for the automated measurement of ONSD and ETD values. It is established that the ONSD and ETD ratio (OER) is a potential biomarker for ICP prediction independent of ethnicity and origin. The OER threshold value is determined by performing statistical analysis on the data of 57 trauma patients obtained from the AIIMS, New Delhi. The automated OER is computed and compared with the conventionally measured ICP by determining suitable correlation coefficients. It is found that there is a significant correlation of OER with ICP (r = .81, p ≤ .01), whereas the correlation of ONSD alone with ICP is relatively less (r = .69, p = .004). These correlation values indicate that OER is a better parameter for the prediction of ICP. Further, the threshold value of OER is found to be 0.21 for predicting raised ICP conditions in this study. Scatter plot and Heat map analysis of OER and corresponding ICP reveal that patients with OER ≥ 0.21, have ICP in the range of 17 to 35 mm Hg. In the data available for this research work, OER ranges from 0.17 to 0.35.
