| Sumario: | The surgical approach to brain tumors often uses preoperative images to visualize the characteristics of pathology, guiding the surgical procedure. However, the usefulness of preoperative images during the surgical procedure is altered by the changes in the brain during the surgery because of craniotomy, inflammation, tumor resection, cerebrospinal fluid (CSF) drainage, among others. For this reason, there is a need to use intraoperative imaging evaluation methods that allow the surgeon to consider these changes, reflecting the real-time anatomical disposition of the brain/tumor. Intraoperative ultrasound (iUS) has allowed neurosurgeons to guide the surgical procedure without exposing the patient to ionizing radiation or interrupting the procedure. Technological advances have made it possible to improve image quality, have smaller probes, and facilitate the use of the equipment, in addition to the introduction of new imaging modalities, such as three-dimensional images, enhanced with contrast, among others, expanding the available options. In the context of these advances, the objective of this chapter was to review the current status of the usefulness and challenges of iUS for brain tumor resection through an in-depth review of the literature and the discussion of an illustrative case. |
