Speckle tracking for third ventricle pulsation detection and quantification

Background: “Speckle tracking” is a new quantification software that allows to measure and to monitor the movement of two selected points (speckles), individually and relative to one another. We applied this technique in order to study the pulsation of the third ventricle and to evaluate the diagnostic potential of this new technique. Method: We recorded video loops in cross sectional insonation planes of the third ventricle by means of a transcranial B-mode imaging device (Philips iu22, sectional S5 – 1 probe). Advanced Quantification Software (Philips QLAB – CMQ Free Deformation function) was used to analyze m…
