Title: Quantitative Analysis of Computed Tomography Images and Early Detection of Cerebral Edema for Pediatric Traumatic Brain Injury Patients: Retrospective Study


Abstract:

The purpose of this study was to identify whether the distribution of HU values across the intracranial area in CT images can be used as an effective diagnostic tool for determining the severity of cerebral edema in pediatric TBI patients.

CT images, medical records, and radiology reports of 70 pediatric patients were collected. Based on radiology reports and the Marshall classification, patients were grouped as mild edema patients (n = 37) and severe edema patients (n = 33). Automated quantitative analysis, using unenhanced CT images, was applied to eliminate artifacts and identify the difference in HU value distribution across the intracranial area between these groups.

The proportion of pixels with HU = 17 to 24 was highly correlated with the existence of severe cerebral edema (p < 0.01). This proportion was also able to differentiate patients who developed delayed cerebral edema from mild TBI patients. A significant difference between deceased patients and survived patients in terms of HU distribution came from the proportion of pixels with HU = 19 to HU = 23 (p < 0.01).

The proportion of pixels with HU value of 17 to 24 in the entire cerebral area of non-enhanced CT image can be an effective basis for evaluating the severity of cerebral edema. With this result, we propose a novel approach for early detection of severe cerebral edema.
