Mithilfe der Kontrastmittelsonografie lässt sich die diagnostische Genauigkeit der
konventionellen Sonografie in vielen Bereichen der HNO-Heilkunde erhöhen. Durch die
Untersuchung
werden Vaskularisation und Gewebeperfusion objektivierbar. Dies bietet vielversprechende
Ansätze, beispielsweise zum Therapiemonitoring metastatischer zervikaler Lymphknoten
oder im
Rahmen der Behandlung vaskulärer Malformationen.
Abstract
With the help of contrast enhanced ultrasound, the diagnostic accuracy of conventional
sonography can be increased in many areas of otorhinolaryngology. Vascularisation
and tissue
perfusion can be objectified through the examination. This offers promising approaches
for
example to monitor the therapy of metastatic cervical lymph nodes or in the treatment
of
vascular malformations. Contrast Enhanced Ultrasound (CEUS) also offers great potential
for
differential diagnosis, for example of thyroid nodules. Valid threshold values for
the
quantitative time intensity curve (TIC) analysis of cervical pathologies are currently
still
not available. Further studies are necessary. As there is currently no license for
the use of
contrast enhanced ultrasound in otorhinolaryngology patients must be informed about
its
off-label use before the examination. This article is intended to provide an overview
of the
current possibilities and to serve as an introduction to the topic.
