Experts explain the three most common diagnostic methods for brain cancer

With the advancement of medical technology, there are more and more diagnostic methods for brain cancer, which are very beneficial to brain cancer patients. So what are the common diagnostic methods for brain cancer ? Let's talk about the common diagnostic methods for brain cancer.

In general, the common diagnosis methods for brain cancer are:

1. Head X-ray

It is the most common method for diagnosing brain cancer. 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 brain cancer. It is helpful for positioning and qualitative diagnosis, but the positive rate of X-ray films is less than one-third, so brain cancer cannot be ruled out due to negative films.

2. Electroencephalogram

It is of great significance for the diagnosis of fast-growing brain cancer in the cerebral hemisphere, as the amplitude and frequency of the diseased side can be seen to be reduced, but it is not very helpful for the diagnosis of brain cancer in the midline, deep in the hemisphere, and under the tentorium. The EEG topography developed after the 1970s can graphically display the location and range of intracranial lesions. It is more sensitive to the diagnosis of brain cancer 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.

3. Brain CT scan

The detection rate of brain cancer can reach over 90%. It is easy to display the size, shape, number, location, density and nature of the lesions, and has clear anatomical relationships. It is currently the main method for diagnosing brain cancer.

The above is an introduction to the common diagnosis methods of brain cancer. I hope it will be helpful to everyone. For more questions about the diagnosis of brain cancer, you can consult our online experts, who will give you detailed answers.
