Phantom tastes are less common and often coexist with phantom smells or other hallucinations. Patients feel that they taste a particular taste when eating or drinking, often causing them to refuse food. It is seen in temporal lobe epilepsy and schizophrenia. What tests are needed for phantom taste? CT cranial examination CT cranial examination is a method of examining the cranial brain through CT. Cranial CT is a new examination method that is convenient, rapid, safe, painless and non-invasive. It can clearly show the anatomical relationships and specific brain tissue structures in different cross-sections of the cranial brain. Thus, it greatly improves the detection rate of lesions and the accuracy of diagnosis. In general, CT has better visualization of human hard tissues than soft tissues. Cranial CT examination is important for the diagnosis of most diseases in the skull, cranium and scalp (including trauma, tumor, inflammation, vascular lesions, poisoning, degenerative and metabolic diseases, etc.). Cranial MRI Examination Cranial MRI examination is an MRI examination of the brain, which is used to observe the presence of lesions in the brain and can clarify whether the patient is due to structural changes in the brain. Intracranial tumors often cause epilepsy, and MRI has an extremely high rate of diagnostic confirmation for low-grade astrocytomas, ganglia, gliomas, arteriovenous malformations and hematomas in the brain. Brain evoked potentials Brain function is examined by brain evoked potentials.
