syngo.CT Brain Hemorrhage

syngo.CT Brain Hemorrhage is an artificial intelligence-driven software designed to analyze non-contrast head CT DICOM images for the suspicion of acute intracranial hemorrhage, aiming to assist clinicians by prioritizing cases for review. Its methodology involves AI learning algorithms processing imaging data to provide notifications of potential ICH with high sensitivity and specificity, thereby acting as an informational triage tool within the radiological workflow.

syngo.CT Brain Hemorrhage is an image processing software utilizing artificial intelligence learning algorithms to assist qualified clinicians in analyzing and prioritizing non-contrast head CT DICOM images. Its primary function is to algorithmically identify findings suspicious of acute intracranial hemorrhage (ICH), providing a notification for worklist prioritization by making case-level output (suspected hemorrhage / no suspected hemorrhage) available to CT scanners or PACS systems. This software acts as an informational tool to support the review process and is not intended for direct diagnostic use, nor does it alter the original medical images. The software's efficacy was demonstrated in a retrospective stand-alone performance study involving 600 anonymized head CT cases from five international sites, with findings compared against a ground truth established by a consensus of three board-certified neuroradiologists. This evaluation yielded a sensitivity of 92.8% (95% CI: 89.3%-95.2%) and a specificity of 94.5% (95% CI: 91.3%-96.5%) for detecting ICH, surpassing the predefined 80% performance threshold, with an average image processing time of 13.67 seconds per case. The underlying science employs AI to analyze imaging data, serving as a triage and notification system that operates in parallel to standard workflows to flag suspicious cases for expedited review by clinicians.
