Objectives

Narrative objectives1

Intracranial pressure (ICP) elevation is associated with poor outcome in patients with traumatic brain injury (TBI), and ICP is one of the key indicators in the management of TBI patient. Although ICP elevation is sometimes estimated from CT images as a substitute for ICP sensor placement, the association between CT images and ICP elevation remains unclear. This study aims to objectively elucidate this association through the utilization of a freely available programming code for CT assessment.

Other related information

We will conduct a retrospective cohort study at Rinku General Medical Center in Japan from April 2014 to August 2023, including all ages of traumatic brain injury (TBI) patients with inserted intracranial pressure (ICP) sensors. ICP values will be compared with CT series taken at the same timing. The 'CT volumetry' will be employed to analyze CT series, visualizing and calculating intracranial volume (ICV) and three density volumes: low-density volume (LDV), middle-density volume (MDV), and high-density volume (HDV). The thresholds for the density areas will be determined as averages by three blinded trauma physicians. The code was developed using Python and the OpenCV module, enabling cost-free and versatile utilization. The primary outcome is ICP value, and we establish an ICP elevation threshold (ICP > 22mmHg) for a dichotomous outcome to assess diagnostic accuracy.
