Deans' stroke musings: FDA Clears Software to Notify Specialists When CT Scan Suggests Stroke

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

FDA Clears Software to Notify Specialists When CT Scan Suggests Stroke

Now if we would know just how fast interventions need to occur to get 100% recovery then we could have targets to shoot for rather than this lazy, it works faster than manual tasks. But that would require brains and effort, neither of which exist in stroke medical leadership.

Viz.AI Contact software that provides artificial intelligence-assisted stroke detection for CT scans and automatically notifies neurovascular specialists by text message got U.S. marketing approval from the FDA, the agency Giving the alert on suspected large vessel infarcts early -- at the time a first-line provider is conducting a standard review of the images -- theoretically gets the specialist involved faster than waiting for a radiologist to complete his or her review of the scans.

The platform is designed to analyze all stroke-protocol CT angiography images of the brain and works with any standard commercial CT scanner. "The system is designed for hospitals to push DICOM [Digital Imaging and Communications in Medicine] imaging data to the cloud where the Viz.AI deep learning artificial intelligence resides," a representative of the company told MedPage Today.

Nonetheless, the application is limited to the analysis of CT scans and should not be used as a replacement of a full patient evaluation or solely relied upon to make or confirm a diagnosis, according to the FDA statement.

Approval for Viz.AI Contact was supported by the ALADIN study wherein the application matched two neuro-radiologists in performance. ALADIN was presented at the International Stroke Conference this year, with an abstract citing sensitivity of 0.97 and specificity of 0.52, with a positive predictive value of 0.74, negative predictive value of 0.91, and overall accuracy of 0.78 in internal carotid artery terminus, middle cerebral artery-M1 large vessel occlusions versus more distal occlusions or no large vessel occlusion.
