Ischemic Stroke Clinical Trial
Official title:
A Prospective Study to Determine Confounding Factors in the Detection of Intracranial Hemorrhage With the Infrascanner
The investigators prospectively want to use the Infrascanner in patients with ischemic stroke, patients with brain surgery, patients with brain tumors, patients with intracranial hemorrhage and patients with a normal CT scan of the brain as part of a diagnostic work-up after head trauma or headache to determine to positive and negative predictive value of the Infrascanner in these different settings.
Infrascanner is a portable device initially designed to detect intracranial hemorrhage in
battlefield traumas. Infrascanner uses near infrared spectroscopy to measure cerebral blood
flow non-invasively. This is achieved by putting the device against the scalp in 4 different
areas (frontal, temporal, parietal, occipital) on the left and right side and by comparing
both sides.This allows for the detection of intracranial hemorrhages with a volume upwards
of 3.5ml and to a depth of 2.5cm. However, little is known about the influence of other
intracranial conditions that could confound the measurements of the Infrascanner (e.g.
ischemic stroke, brain surgery, brain tumors,...).
Therefore, the investigators prospectively want to use the Infrascanner in patients with
ischemic stroke, patients with brain surgery, patients with brain tumors, patients with
intracranial hemorrhage and patients with a normal CT scan of the brain as part of a
diagnostic work-up after head trauma or headache to determine the positive and negative
predictive value of the Infrascanner in these different settings.
