Rapid Ventricular Pacing During Cerebral Aneurysm Surgery: a Study Concerning the Safety for Heart and Brain

Rapid ventricular pacing (RVP) is a technique to obtain flow arrest for short periods of time during dissection or rupture of the aneurysm. RVP results in an adequate fall in blood pressure which presents as an on-off phenomenon. However it is not clear whether repetitive periods of pacing are harmless …

Estimating Brain Biomechanics Using MRI

Objective: In this study we will develop and apply imaging techniques to perform the first three-dimensional (3-D) measurements of brain biomechanics during mild head movement in healthy human subjects. Biomechanics is the application of mechanics, or the physical principles in action when force is applied to an object, to the …
