Abstract:

In the surgical resection of intracranial tumors, exact localization of the intracranial mass is the key to achieving complete tumor resection to reduce the recurrence rate but preserve or improve the patient′s neurological functions. At present, imaging guided neuronavigation techniques include intraoperative CT (iCT), intraoperative MRI (iMRI), and intraoperative ultrasound (ioUS). iCT and iMRI are restricted not only by time and space, but also by expensive equipment and the need for a dedicated room. Therefore, their use has been limited. IoUS ensures rapid, reproducible, and cost-effective real-time intraoperative imaging without those limitations to help surgeons understand the spatial location of the lesions after craniotomy. In this regard, standard B-mode ultrasound offers significantly useful morphologic information, and different Doppler modalities as well as contrast-enhanced ultrasound offer information regarding tumor vascularization and perfusion. Intraoperative elastosonography appears to be of value in evaluating tumor borders, parenchymal infiltration, and tumor consistency, which needs further research. This paper introduces the application of ioUS in neurosurgery.

Key words: Intracranial tumors, Contrast-enhanced ultrasound, Elastosonography
