Abstract
Traumatic brain injury (TBI) is not only an acute condition but also a chronic disease
with long-term consequences. Intracranial hematomas are considered the primary consequences
that occur in TBI and may have devastating effects that may lead to mass effect on
the brain and eventually cause secondary brain injury. Emergent detection of hematoma
in computed tomography (CT) scans and assessment of three major determinants, namely,
location, volume, and size, is crucial for prognosis and decision-making, and artificial
intelligence (AI) using deep learning techniques, such as convolutional neural networks
(CNN) has received extended attention after demonstrations that it could perform at
least as well as humans in imaging classification tasks. This article conducts a comparative
review of medical and technological literature to update and establish evidence as
to how technology can be utilized rightly for increasing the efficiency of the clinical
workflow in emergency cases. A systematic and comprehensive literature search was
conducted in the electronic database of PubMed and Google Scholar from 2013 to 2023
to identify studies related to the automated detection of intracranial hemorrhage
(ICH). Inclusion and exclusion criteria were set to filter out the most relevant articles.
We identified 15 studies on the development and validation of computer-assisted screening
and analysis algorithms that used head CT scans. Our review shows that AI algorithms
can prioritize radiology worklists to reduce time to screen for ICH in the head scans
sufficiently and may also identify subtle ICH overlooked by radiologists, and that
automated ICH detection tool holds promise for introduction into routine clinical
practice.
