Brain tumors are diagnosed through a clinical exam and the results of tests such as CT and MRI. The neurosurgeon discusses available treatments with the patient. Treatments which neurosurgeons provide include surgical resection and Gamma Knife Radiosurgery.
Neuronavigation provides the neurosurgeon a probe, which when placed on or in the patients head, shows him what is just beyond the probe in all directions. The images are presented in 3D on a computer screen.
This information is helpful even before the surgery begins since it allows for planning the best approach to the tumor. During the procedure neuronavigation guides the neurosurgeon directly to the tumor and also informs him of the locations of sensitive structures within the brain.
In many cases neurosurgeons use an operating microscope to obtain the best view of the surgical field.
