Red dot® CTH V1 processes adult non-contrast CT Head at the point of acquisition and, within 5 minutes, provides the following key outputs:

Intracranial Haemorrhage (ICH)

Acute Infarct

High Confidence Normal (HCN)
An AI enabled pathway not only significantly reduces time to treatment but also reduces costs and increases radiological resources
![](https://www.behold.ai/wp-content/uploads/2022/03/rad-teal-1.png)
Increase radiological capacity
CTH identified as HCN (normal with a very high degree of confidence) can be autonomously reported, reducing radiology workload and reliance on outsourcing

Reduce time-to-treatment
CTH identified as having acute abnormalities (haemorrhage or acute infarct) are prioritised for hot-reporting and fast-tracked for appropriate treatment

How does our red dot® CT Head solution perform?
![](https://www.behold.ai/wp-content/uploads/2022/03/CT-HCN-icon.png)
High confidence normal
54.3%
of Normal examinations removed with a negative predictive value (NPV) of 0.93 (compared to 0.87 for radiologists)

Intracranial haemorrhage
93.1%
of radiologist false negatives for ICH identified

Acute infarct
69.1%
of radiologist false negatives for acute infarct identified
Our evidence
“Validation of an artificial intelligence solution for acute triage and rule‐out normal of non‐contrast CT head scans” published in Neuroradiology: We demonstrated state-of-the-art performance with AUCs of 0.988, 0.933 and 0.939 for ICH, Acute Infarct and Normal respectively. Red dot® identified 91.3% ICH and 61.9% acute infarcts missed by radiologists, and demonstrated the ability to remove up to 54.3% of Normal examinations with a negative predictive value (NPV) of 0.93 (compared to 0.87 for radiologists).
The clinical need for red dot® is clear...

CTH scans identified as normal
Patients who have no acute clinical abnormality, with an NPV of 93%, and remove >60.65% of all CTH scans from the reporting workload.
