Brain tumor imaging with transcranial sonography: state of the art and review of the literature.

Transcranial sonography (TCS) is a widely used non-invasive bedside method to evaluate the brain, its vessels, perfusion and pathologies. Transcranial brain tumor sonography emerged in the early nineties and while B-mode imaging and Color-Doppler have acquired widespread use, especially for intraoperative imaging, other ultrasound modalities such as Perfusion Imaging are applied more in the research field. The aim of this review is to give an overview of the different ultrasound modalities and their respective application in sonographic brain tumor imaging. © Georg Thieme Verlag KG Stuttgart · New York.
