How to check for brain cancer

People may be very afraid of brain tumors in their daily lives, because brain tumors can cause great harm to patients and may even lead to their death. Therefore, many patients are very worried and afraid when they first learn that they have brain tumors, and even have thoughts of suicide. Now let us ask the editor to introduce how to check for brain cancer?

1. Imaging examinations include cranial X-rays, radionuclide brain angiography, ventriculography and cisternography, cerebral angiography, etc. These examinations used to be important diagnostic methods for neurological diseases, not only for locating lesions, but also for qualitative diagnosis. However, except for X-rays, these examinations are all damaging and should be carefully selected according to needs.
2. CT examination
CT has a diagnostic rate of more than 90% for intracranial tumors and is one of the main diagnostic methods for brain tumors. Intracranial tumors are histologically quite different from normal brain tissues. Different tissue structures have different CT values ​​and show different densities, thus showing lesions on CT images.
3. Magnetic resonance imaging
MRI can provide clear anatomical background images, especially head images that are not disturbed by artifacts in the posterior cranial fossa, with distinct contrast between gray and white matter in the brain, and can be used for coronal, sagittal, and axial sectioning, which is superior to CT. Intravenous injection of a paramagnetic substance, gadolinium (Gd) compound (Gd-DTPA), can significantly shorten the T-1 relaxation time of tissues, so it can be used as an enhancer to increase the contrast between lesions and normal brain tissues and improve the resolution of MRI. It is now generally believed that MRI should be the first choice for the diagnosis of neurological lesions.
