What tests are done for brain tumors

When you feel unwell, you usually choose to go to the hospital for a check-up. Different symptoms require different examinations. So what examinations are required for brain tumors? People with brain tumors should not be too sad. Sometimes they are benign and can be completely recovered through surgery. The common examinations for brain tumors include angiography, head X-rays, etc. These examinations are very accurate in finding out the cause of the disease.

1. Imaging examination

Including skull X-ray, radionuclide brain angiography, ventriculography and cisternography, cerebral angiography, etc. These examinations were once important diagnostic methods for neurological diseases. They not only have the significance of locating lesions, but also have certain qualitative diagnostic value. However, except for X-rays, these examinations are all damaging and should be selected carefully according to needs.

2. CT examination

The diagnosis rate of CT for intracranial tumors can reach over 90%, making it one of the main diagnostic methods for brain tumors. There are considerable histological differences between intracranial tumors and normal brain tissues. Different tissue structures have different CT values ​​and exhibit 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 interfered by posterior cranial fossa artifacts, have sharp contrast between brain gray and white matter, and can be sliced ​​in coronal, sagittal, and axial planes, making them superior to CT. Intravenous injection of a paramagnetic substance gadolinium (Gd) compound (Gd-DTPA) can significantly shorten the T-1 relaxation time of tissues. Therefore, 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 diseases.
