How should glioma be diagnosed

Gliomas, also known as neurogliomas, are a type of brain tumor and are generally malignant brain tumors. Therefore, active examination and treatment of gliomas are very important. Once symptoms appear, treatment should be started immediately. Let's take a look at how gliomas should be diagnosed.

The first is the electroencephalogram (EEG). Affected by the infiltration of the tumor, the size of the tumor, the intracranial pressure, and the degree of cerebral edema, the brain tumor in the early stage is easy to appear once, while the deep brain tumor has little change. The main centenary line of benign oligodendroglioma and astrocytoma is the localized delta wave, while most of the multiform glioblastomas show extensive delta waves; the second is radioisotope scanning (Y-ray brain map). Tumors with fast growth and rich blood supply have high blood-brain barrier permeability and high isotope absorption rate. For example, multiform glioblastoma shows isotope concentration images, and there may be low-density areas in the middle due to necrosis and cyst formation, which need to be distinguished from metastatic tumors based on their shape and multiplicity. The concentration of more benign gliomas such as astrocytoma is lower, often slightly higher than the surrounding brain tissue, and the image is not clear, and some may be negative findings; the third is radiological examination. Including skull plain film, ventriculography, computer tomography, etc. Skull plain film can show signs of increased intracranial pressure, tumor calcification and displacement of pineal calcification. Ventriculography can show displacement of cerebral blood vessels and tumor blood vessels. These abnormal changes are different for different types of tumors in different locations, which can help locate and sometimes even determine the diagnosis. In particular, CT scanning has the greatest diagnostic value. The intravenous injection of contrast agent to enhance scanning has a positioning accuracy of almost 100%, and the accuracy of qualitative diagnosis can reach more than 90%. It can show the location, range, shape, brain tissue reaction and ventricle compression displacement of the tumor. However, it still needs to be combined with comprehensive clinical considerations to make a clear diagnosis; the last is nuclear magnetic resonance. The diagnosis of brain tumors is more accurate than CT, the image is clearer, and small tumors that CT cannot show can be found. Positron emission tomography can obtain images similar to CT, and can observe the growth and metabolism of tumors and distinguish benign and malignant tumors.

The above is what the editor introduced to you about what examinations are needed to diagnose brain glioma. I believe everyone has a certain understanding of it. Then actively cooperating with the doctor to treat the disease is what patients should do most. Timely treatment of brain tumors is not good, but being able to control the development of the disease is also a good choice.
