intraoperative MRI

Also written as: iMRI — intraoperative magnetic resonance imaging

Real-time magnetic resonance imaging performed during brain surgery to guide tumor resection and assess completeness.

Full Definition

Intraoperative MRI (iMRI) is a specialized imaging technique that allows neurosurgeons to obtain real-time magnetic resonance images during brain tumor surgery. This technology enables surgeons to assess the extent of tumor resection, identify residual tumor tissue, and make real-time adjustments to maximize tumor removal while preserving critical brain structures. The procedure typically requires a specially designed operating room with MRI capabilities or a mobile MRI unit. This technology has significantly improved surgical outcomes in brain tumor resection.

Usage

Usage note: Always hyphenate when used as adjective; iMRI acceptable after first use.
