Intraoperative Ultrasonography in Neurosurgery: Experience of an Institution

Abstract

Objective Intraoperative ultrasound (IOUS) is an imaging method that can be used in various neurosurgical procedures. It assists in the removal of brain tumors, hematomas, in the insertion of ventricular catheters, and in spinal and peripheral nerve surgeries. The original studies using IOUS were performed with devices that produced lower-quality images, generating little interest in their use. The introduction of ultrasound devices that yielded higher-quality images associated with a relative low cost and ease of use rendered IOUS attractive. Thus, we started using it in multiple neurosurgical procedures, studying its practicality, efficacy and limitations.
