What are the detection indicators of brain cancer

Mainly because brain tumors have seriously affected people's lives and health in recent years, more and more people have begun to pay attention to this disease and actively carry out prevention work. So, in order for everyone to find out that they are sick as early as possible, what are the detection indicators of brain cancer?

1. Imaging examination

These include cranial X-rays, radionuclide brain angiography, ventriculography and cisternal angiography, and cerebral angiography. These examinations were once 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 very high diagnosis rate 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 clear contrast between gray and white matter in the brain, and can be used for coronal, sagittal and axial section 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.
