In this review, methodological aspects of cerebral perfusion imaging with ultrasound signal
enhancing agents are described. The various experimental bases, contributing to the …

Perfusion harmonic imaging of the brain is a new ultrasound technique for assessing
cerebral perfusion. In a patient with acute middle cerebral artery infarction, this method …

Zusammenfassung Studienziel: Die Darstellung von Ultraschall-Kontrastmitteln im
Hirngewebe mittels Harmonic Imaging ist ein neues Verfahren, um Hirnperfusion …

Background and Purpose—Through harmonic gray-scale imaging, it is possible to analyze
brain tissue perfusion with different ultrasound methods. Methods—In 12 healthy volunteers …

Fast visualisation of cerebral microcirculation supports diagnosis of acute stroke. However,
the commonly used CT/MRI-based methods are time consuming, costly and not applicable …

With ultrasound (US) contrast agent (UCA) continuous infusion providing a steady state,
mean tissue microbubble velocity can be assessed by analyzing the reappearance rate after …

The aim was to evaluate phase-inversion harmonic imaging (PIHI) with respect to brain
perfusion imaging using a novel “bilateral approach”(depth of examination: 150 mm) and …

Analysis of contrast diminution kinetics after bubble destruction is a new aspect in harmonic
imaging. The purpose of this study was to investigate this approach to human cerebral …

The fast visualisation of cerebral microcirculation supports diagnosis of acute
cerebrovascular diseases. However, the commonly used CT/MRI-based methods are time …

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 …
