Neurosurgical diagnosis and intervention has evolved through improved neuroimaging, allowing better visualization of anatomy and pathology. This article discusses the various systems that have been designed over the last decade to meet the requirements of neurosurgical patients and opines on the potential future developments in the technology and application of intraoperative MRI. Because the greatest amount of experience with intraoperative MRI comes from its use in brain tumor resection, this article focuses on the origins of intraoperative MRI in relation to this field.

Intraoperative assessment of tumor margins can be challenging; as neoplastic cells may extend beyond the margins seen on preoperative imaging. Real-time intraoperative ultrasonography (IOUS) has emerged as a valuable tool for delineating tumor boundaries during surgery. However, concerns remain regarding its ability to accurately distinguish between tumor margins, peritumoral edema, and normal brain tissue.

Objective: Anterior cruciate ligament (ACL) reconstruction using tendon autograft requires imaging to evaluate graft adequacy. Ultrasound (US) offers an efficient adjunct to MRI; however, the utility of US is variable in prior literature and should be investigated. The primary aim of this study is to provide a statistical appraisal of literature assessing correlation of preoperative US measurements with intraoperative size of autografts during ACL reconstruction.

Objective: The extent of resection (EOR) is an important prognostic factor for both low- and high-grade gliomas. Intraoperative MRI (iMRI) has been used to increase the EOR in glioma surgery. While a recent study reported differences between iMRI and early postoperative MRI (epMRI), their specific relationship to postoperative clinical symptoms remains unclear.

Spinal schwannomas are benign, slow-growing tumors originating from Schwann cells, constituting 25 to 30% of primary spinal neoplasms and most frequently arise from sensory nerve roots in the cervical or thoracic spine. 1 2 3 Although generally nonaggressive, their growth can result in significant neurological deficits due to compression of surrounding structures such as the spinal cord or nerve roots. 4 5 Patients commonly present with localized pain, muscle weakness, and sensory disturbances.

Hibernomas are rare, benign neoplasms characterized by the presence of brown adipose tissue. Although these tumors may arise in any region of brown fat, they predominantly occur in the thigh, shoulder, back, and neck. Hibernomas are rarely found in mammary tissue, with a higher prevalence in females than males.
