OBJECTIVE: To characterize changes in regional blood flow (rCBF) during and after a
period of arterial occlusion and determine the effect on rCBF and on the extent of infarction …

Background and Purpose—Initial reports indicate that transcranial harmonic imaging after
ultrasound contrast agent bolus injection (BHI) can detect cerebral perfusion deficits in acute …

The bolus kinetic in ultrasonic cerebral perfusion imaging is the most favored data
acquisition and processing technique. However, there has not yet been convincing evidence …

Aim Perfusion harmonic imaging (PHI) has been used for several years now in neurological
as well as other patients. The aim of the study was to compare PHI with perfusion-weighted …

Ziel: Die gestörte Hirnperfusion bei Patienten mit akutem Hirninfarkt kann mit der
sonographischen Perfusionsbildgebung nach Ultraschallkontrastmittelbolusinjektion …

Objective. The authors evaluate blood flow velocities in the medial cerebral artery (MCA)
and the basilar artery using magnetic resonance (MR) phase contrast technique in …

Following middle cerebral artery occlusion, tissue outcome ranges from normal to infarcted
depending on depth and duration of hypoperfusion as well as occurrence and efficiency of …

Background and Purpose Gas bubbles of ultrasound contrast agents resonate at
frequencies used for diagnostic ultrasound and produce harmonics or multiples of the …

Ziel: Die transkranielle Perfusionssonografie (TPS) ist eine neue, nicht invasive Methode zur
Darstellung der Hirnperfusion. Ziel war die Bewertung einer neuen TPS-Modalität, die einen …

Introduction: The aim of this study was to assess the effect of Albunex, a vascular contrast
agent based on albumin‐coated air microbubbles, on pulsed Doppler and colour‐coded …
