The diagnosis of brain tumors are primarily radiological. These are what the neurosurgeon wants when he suspects a brain tumor; CT (computed tomography), MR (magnetic resonance), DSA (digital cerebral angiography), PET (positron emission tomography) which can be withdrawn with or without injecting contrast agents. These can give the neurosurgeon a more detailed view of the structure of the brain, even more than when they see after opening the skull.
Also tests that can display the function of various regions of the brain, such as EEG (Electroencephalography), MEG (Magneto Electroencephalography) and Perfusion MR, Diffusion MR, MR Spectroscopy, MR Tractography, Functional MR can be used. In other words, the tumor can damage the brain’s specific areas, and this damage in the brain’s functioning can be shown.
In addition to all of these, since there is the possibility of an inflammatory event or a “metastasis”; blood tests are necessary. Of course, in this process; it may be necessary to take into consideration the recommendations of doctors from other branches of medicine.
