iMRI technology gives surgeons “real-time” images during procedures.
Norton Healthcare was one of the nation’s first health care providers to install and utilize intraoperative magnetic resonance imaging (iMRI) technology. iMRI enables surgeons to use computer-assisted, image-guided technology during surgical procedures. The iMRI provides the surgeon with “real-time,” continuous images of the brain and spine during surgery. The iMRI uses a strong magnetic field, radio-frequency signals and advanced computer technology to create precise images of the surgical field as the surgeon works. These images are displayed on a monitor above the surgeon’s head during the procedure.
In addition to providing surgeons with real-time images, iMRI also offers these benefits:
- Sharper imagery: iMRI provides the surgeon with a picture of the patient’s brain at the start of surgery to confirm placement of the initial incision. Then up-to-the-minute images help the surgeon base decisions on the brain’s most current status, such as if it has shifted or accumulated fluid around it. Without these images the surgeon must rely on instinct, which can result in larger incisions, more extensive surgery and longer operating time.
- More thorough removal of brain tumors: The naked eye can’t always distinguish between a tumor and normal brain tissue, making it sometimes difficult to completely remove a tumor, or more brain tissue is removed than necessary. By using the iMRI, surgeons may be able to avoid removing or damaging healthy brain tissue around the tumor, which may help patients avoid cognitive or physical disabilities following surgery. Recent studies show that iMRI revealed residual tumors in one-third of cases where surgeons thought tumors had been completely removed. Surgeons were then able to completely remove the tumors, avoiding a possible second surgery.
- Diagnostic advantages: The open design of the iMRI means patients can be imaged in a wider variety of positions. This can mean a more accurate diagnosis of the condition and more detailed images than those produced by traditional MRI.
