3T Intraoperative MRI Revolutionary Technology in Brain Surgery
Understanding an Intraoperative MRI
MRI stands for Magnetic Resonance Imaging. MRI utilizes a powerful magnetic field and radio waves to generate detailed pictures of the inside of your body using computer software.
Traditionally the patient underwent an MRI scan before the surgery and based on these images the surgery is performed and later the patient is again transferred to the MRI room to reconfirm if the surgery was performed as planned. In case any abnormality is found the patient is subject to another surgery to correct the abnormality. This cycle might repeat a couple of-of times.
Intraoperative MRI in Neurosurgery
Intraoperative Magnetic Resonance Imaging or IMRI is used by the neurosurgeons to visualize the patient’s brain during surgery without the need to move the patient out of the operation theater.
This cutting-edge technology helps to create accurate pictures of the brain that guide the neurosurgeons to remove tumors of the brain and other abnormalities during operation in a single setting.
Advantages of Intraoperative MRI in Neurosurgery
Though doctors use imaging tests to plan brain surgery, real-time images created with Intraoperative MRI are crucial to:
- Identify abnormalities if there is brain shift. The brain often shifts during a surgery, which makes pre-surgical imaging inaccurate. Intraoperative MRI gives surgeons the most accurate real-time images of the brain.
- Distinguish normal brain tissue from abnormal brain tissue. Differentiating the edges of a brain tumor and separating the normal tissue from abnormal tissue is a difficult task. Intraoperative MRI helps to confirm that the entire brain tumor is removed completely.
How an Intraoperative MRI functions
MRI is especially useful for imaging the brain using radio waves and a magnetic field to create detailed visuals of the tissues and organs in our body.
An Intraoperative MRI is similar to a regular MRI setup, but it is specially re-engineered to be stationed inside the operation theatre itself so that the surgeon can get images as frequently as needed during the surgery
When and how often MRI images are captured during surgery depends on the procedure and the patient’s condition.
