Artificial Intelligence Analysis of Initial Scan Evolution of Traumatic Brain Injured Patient to Predict Neurological Outcome
Artificial Intelligence Analysis of Initial Scan Evolution of Traumatic Brain Injured Patient to Predict Neurological Outcome
We assume that an early iterative automatic CT scan analysis (D0, D1 and D3) by different AI
 approaches will allow an early differentiation of the tissues evolution after TBI. Our
 objective is to couple theses scan profiles to a neurological evolution, measured by
 therapeutic intensity.
Traumatic brain injury is a common and serious pathology, responsible of an important
 morbi-mortality. The TBI can be consider as a complex set of nosological entities of
 different evolution with difficult early identification whereas the main issue of this
 pathology depends on prevention and management of the lesions caused by the initial cerebral
 aggression.

 Different evolutionary profiles seems to exist and sometimes coexists: edema evolution,
 hemorrhagic transformation and/or cerebrospinal fluid (CSF) resorption issues with
 hydrocephalus apparition.

 Currently, there is no Imaging methods that can be used in every day clinical management that
 allows a visualization, quantification and prediction of these different lesional evolutions

 CT scan is the reference imaging method for TBI patient monitoring. It allows a lesion
 description, a therapeutic adaptation and an evaluation of the prognostic.

 Even if it is used as a routine examination, the analysis of cerebral scanners remains manual
 and a non-quantitative one, which make a little informative analysis as far as lesions
 evolution is concerned.

 Recently it has been established the automatic MRI analysis with AI approach allows:

 1. - To show aspects of images that can't be seen to the naked eye

 2. - To automatically segment and quantify the different tissues (edema, hemorrhage...).
 First tests on this kind of analysis on CT scans shows that this technology can be
 transferred from MRI to CT scans and more importantly it brings out new quantitative
 informations on cerebral lesions evolution.
