MRI creates detailed images of your body’s organs and tissues by using a magnetic field and radio waves. MRI is very useful for imaging the brain. The surgeon may request iMRI imaging at several moments during the procedure. The frequency with which the surgeon creates images during surgery is determined on your procedure and condition. Intraoperative magnetic resonance imaging (iMRI) is a surgical method that produces images of the brain. Neurosurgeons rely on iMRI technology to obtain precise images of the brain that aid in the removal of brain tumors and the treatment of other disorders such as epilepsy.
Uses for (iMRI)
Doctors use iMRI to assist in surgery to treat:
- Dystonia
- Epilepsy
- Essential tremor
- Parkinson’s disease
- Brain tumor
- Pediatric brain tumors
- Pituitary tumors
- Glioma
- Neuropsychiatric disorders
Advantages of iMRI
Although doctors use imaging tests to plan brain surgery, real-time images created with iMRI are crucial:
- If the brain has shifted, look for anomalies. Because the brain frequently changes during surgery, pre-surgical imaging is not always precise. Imaging with iMRI during surgery assists surgeons in providing the most accurate information.
- Differentiate between abnormal and normal brain tissue. It might be difficult to detect the margins of a brain tumor and to distinguish between normal and malignant tissue. Imaging with an iMRI during surgery helps confirm that the entire brain tumor was successfully removed.
- Protect critical structures. A minimally invasive treatment known as laser interstitial thermal therapy (LITT) allows surgeons to treat epilepsy by heating tissue and rendering it inactive, stopping the flow of seizures. Surgeons can also keep temperatures low enough to minimize harm throughout the procedure by employing iMRI to monitor brain temperature. Surgeons can use MR-guided ultrasound to focus ultrasound energy on areas of the brain that cause epilepsy without performing surgery.
Intraoperative MRI allows surgeons to remove some brain tumors more completely. As a result, iMRI has become the gold standard for many operations to remove specific brain tumors.
