Can glioma be detected by B-ultrasound?

Tumor is an extremely scary word for us. Tumor has always been a major problem faced by the medical community. In recent years, the incidence and mortality of tumors have been increasing year by year. If tumors can be diagnosed early, the survival rate of tumors may be improved to a certain extent. So, can glioma be detected by B-ultrasound? What are the methods of detection?

1. Ultrasound examination

It can help determine the side and observe whether there is hydrocephalus. For infants, B-mode ultrasound scans can be performed through the anterior fontanelle to show tumor images and other pathological changes.

2. Electroencephalogram

On the one hand, the EEG changes of gliomas are limited to changes in brain waves at the tumor site. On the other hand, there are general and widely distributed changes in frequency and amplitude. These are affected by tumor size, infiltration, degree of brain edema, and increased intracranial pressure. Shallow tumors are prone to localized abnormalities, while deep tumors have fewer localized changes. In more benign astrocytomas, oligodendrogliomas, etc., localized delta waves are mainly manifested, and some epileptic waveforms such as spikes or sharp waves can be seen. Large glioblastoma multiforme can show widespread delta waves, which can sometimes only be determined on one side.

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.
