Image-guided surgury
|
One option for treating an accessible tumor (one that can be
removed without a high risk of neurological damage) is surgery.
There are many new techniques and tools that allow neurosurgeons
to reach tumors previously considered inaccessible. These include:
- Microsurgery, in which the surgeon uses a high-powered
microscope to get a magnified view of the operating area.
This makes it easier to see and remove a tumor while sparing
surrounding healthy tissue.
- Stereotactic procedures, in which a computer uses
information from a CT scan or an MRI to create a three-dimensional
map of the operation site. The neurosurgeon uses this map to guide
computer-assisted tools to target certain difficult-to-reach tumors
with greater precision. Many procedures can be performed using this
approach, including biopsy, certain types of surgery and planting
radiation pellets in a tumor.
