What tests are needed if glioma is suspected

Glioma is a brain nerve tumor, which has a certain degree of cancerous transformation, so people should pay more attention to this disease. How can we detect it as early as possible and treat it as soon as possible? This requires us to regularly check our bodies. So what kind of examinations should be done if glioma is suspected? Let's learn about the examinations for glioma.

What tests should be done if you suspect a brain glioma? The main ones are as follows:

1. Head X-ray: It helps to understand whether there is increased intracranial pressure, local destruction or hyperplasia of the skull, enlargement of the sella turcica, displacement of pineal calcification and pathological calcification in the brain tumor. It is helpful for positioning and qualitative diagnosis, but the positive rate of X-ray is less than one-third, so brain tumors cannot be ruled out due to negative X-ray results.

2. Biochemical determination: For patients with pituitary tumors, especially those with excessive secretion of anterior pituitary hormones, blood biochemical tests can be used to confirm the condition. Prolactin, growth hormone, adrenocorticotropic hormone, thyroid stimulating hormone, gonadotropin, etc. can be tested to clarify the nature of pituitary disease. Among them, prolactinoma is the most common, accounting for about 50%, followed by growth hormone adenoma and adrenocorticotropic hormone adenoma.

3. Magnetic resonance imaging: It can not only clearly show the size of the tumor, but also directly see whether the blood vessels in the tumor are rich, and use the injection enhancement or no enhancement to judge the richness of its blood supply. In particular, it can show the entire morphology of brain tissue, making the brain almost "transparent". This provides an important basis for us to choose the surgical approach.

4. EEG examination: It has a 0.0 positioning value for fast-growing brain tumors in the cerebral hemispheres. It can be seen that the amplitude of the affected side is reduced and the frequency is slowed down, but it is not very helpful for the diagnosis of brain tumors in the midline, deep in the hemisphere, and under the tentorium. The EEG topography developed after the 1970s can show the location and range of intracranial lesions in a graphical way. It is more sensitive to the diagnosis of brain tumors than conventional EEG. Its main manifestation is abnormal slow wave power in the tumor area and around the tumor area. It is an effective screening method before CT examination.

5. Radiological examination: Radiological examination mainly includes skull plain film, ventriculography, computer tomography, etc. The doctor will make a judgment based on the changes and metastasis of brain tissue in the film.
