Rapid ICH 3.0 and Rapid Hyperdensity are designed to support clinicians managing intracranial hemorrhage, including hemorrhagic stroke and head trauma. Two studies presented at the International Stroke Conference 2023 evaluated these technologies.
The studies were conducted by Dr. Anirudh Sreekrishnan of Stanford Medicine and co-authors and were presented by Dr. Sreekrishnan at ISC.
Key takeaways:
- Rapid ICH 3.0 showed 97.84% sensitivity and 99.52% specificity for intracranial hemorrhage detection in the study discussed.
- Rapid Hyperdensity measurements were highly correlated with expert manual measurements of hemorrhage volume.
- The studies examined how automated detection and volume measurement can support intracranial hemorrhage triage and follow-up.
Rapid ICH 3.0 showed high specificity with few false-positive detections
The latest version of Rapid ICH evaluated non-contrast CT scans for intracranial hemorrhage. In the peer-reviewed Rapid ICH 3.0 study, the software showed 97.84% sensitivity, 99.52% specificity, 99.56% positive predictive value and 97.65% negative predictive value.
The peer-reviewed analysis included 881 NCCT examinations. The software processed exams in under one minute and detected multiple hemorrhage subtypes.
Rapid Hyperdensity measurements correlated with manual hemorrhage-volume measurements
Dr. Sreekrishnan and co-authors also evaluated whether Rapid Hyperdensity could automatically quantify hemorrhage volume and detect changes on follow-up NCCT scans. Expert neuroradiologists and the software evaluated baseline and 24-hour follow-up scans from 127 patients.
The peer-reviewed study found a high correlation between automated and manual baseline hemorrhage-volume measurements and between measurements of change on follow-up imaging. For detecting ICH expansion, the software had 94.12% sensitivity and 97.27% specificity.
Streamlining triage-and-transfer decision-making
Rapid ICH and Rapid Hyperdensity automatically process non-contrast CT images and provide findings that can give clinicians additional context for triage and transfer decisions. Rapid ICH 3.0 assesses scans for intraparenchymal, intraventricular, subdural and subarachnoid hemorrhage.
