Intraoperative magnetic resonance imaging (iMRI) is a procedure to create images of the brain during surgery. Neurosurgeons rely on iMRI technology to create accurate pictures of the brain that guide them in removing brain tumors and other abnormalities during operations.
Though doctors use imaging tests to plan brain surgery, real-time images created with iMRI are crucial to:
Distinguish abnormal brain tissue from normal brain tissue. It can be difficult to distinguish the edges of a brain tumor and separate normal tissue from abnormal tissue. Imaging with iMRI during surgery helps confirm successful removal of the entire brain tumor.
Intraoperative MRI allows surgeons to achieve a more complete removal of some brain tumors. For this reason, iMRI has become the standard of care for operations to remove certain brain tumors.
MRI uses a magnetic field and radio waves to create detailed images of the organs and tissues in your body. MRI is especially helpful for imaging the brain.
To utilize MRI technology during surgery, doctors use special imaging systems and operating rooms, including:
At certain points in your operation, the surgeon may request imaging with iMRI. When and how often iMRI images are created during surgery depends on your procedure and your condition.
Doctors use iMRI to assist in surgery to treat:
Doctors use iMRI to assist in surgery to treat brain tumors, gliomas, and pituitary tumors. They also use it to assist in surgery to treat epilepsy, essential tremor, dystonia, and Parkinson's disease. IMRI can also be used to assist in surgery to treat brain and mental health disorders.
Brain surgeons use intraoperative magnetic resonance imaging, or iMRI, to create real-time brain images during surgery. MRI uses a magnetic field and radio waves to create detailed images of the brain. To use MRI technology during surgery, doctors use portable iMRI devices that are moved into the operating room to create images. They may also use nearby iMRI devices that are kept in a room next to the operating room so doctors can easily move you there for imaging during surgery. At certain points during an operation, the surgeon may request imaging with iMRI.
