What is brain tumor diagnosis?

Diagnosis of brain tumors includes the following: 1. History and physical examination: The doctor will ask the patient about symptoms, family history, etc., and conduct a comprehensive physical examination to get an initial understanding of the disease.2. Imaging: Magnetic resonance imaging (MRI) of the head: provides detailed images of brain structure, helping to discover the location, size, and shape of the tumor. Computed tomography (CT): can scan the brain quickly to detect brain masses or other abnormalities. Positron emission tomography (PET): can detect brain metabolism, which is helpful in the diagnosis of certain tumors. 3. Neuropathology examination: brain biopsy: A biopsy or surgery to obtain a sample of brain tissue for pathological analysis to determine the type and grade of the tumor. Cytological examination: Cytological analysis of cerebrospinal fluid or other body fluids to help diagnose certain brain tumors. Other examinations: EEG: To detect electrical activity in the brain and to help diagnose diseases such as epilepsy. Cerebral angiography: The injection of contrast medium to observe the cerebral vessels may assist in the diagnosis of certain brain tumors. The diagnosis of brain tumors usually requires a combination of the results of multiple methods and the specific conditions of the patient. In addition, in difficult cases or specific types of brain tumors, further genetic testing or expert consultation may be required. It is important to note that brain tumor diagnosis requires professional evaluation and judgment. If brain tumor is suspected or related symptoms occur, seek medical attention promptly for detailed examination and diagnosis. Early diagnosis and treatment are essential to improve the treatment effect and survival rate of brain tumor. At the same time, patients and family members should maintain a positive attitude in the face of brain tumors, cooperate with doctors' treatment plans, and pay attention to their physical and mental health.
