This study uses a Doppler ultrasound technique being developed at the University of Leicester called \"Brain Tissue Velocimetry\" (Brain TV), to investigate brain tissue motion over the cardiac cycle.
Brain motion is highly sensitive to heart and brain biomechanics, but the impact of brain injury on brain tissue motion has yet to be explored. Preliminary brain tissue motion measurements from a small number of patients suggest that brain biomechanics may be disturbed in the presence of brain injury. This study combines transcranial tissue Doppler (TCTD) ultrasound with brain magnetic resonance imaging (MRI) to establish whether analysis of brain tissue motion provides clinically useful information for emergency diagnosis and monitoring of suspected stroke.

Doppler ultrasound technique called "Brain Tissue Velocimetry" (Brain TV), to investigate brain tissue motion over the cardiac cycle.
Brain MRI for investigation of brain tissue motion in the presence of suspected stroke.
University of Leicester
Leicester, United Kingdom
MRI measurement
This study will perform brain MRI for brain tissue motion for selective patients with suspected stroke.
Time frame: Up to 5 days.
TCTD measurement
The study will generate a library of Brain TV measurements for exploratory (descriptive) analysis and imaging of brain tissue pulsations in patients with suspected stroke to evaluate the potential for clinical device development.
Time frame: Up to 5 days.
