MRI and EEG are two completely different testing methods, and it is not possible to simply comment on which one is more accurate, because the two tests are applicable to different situations, and both have their own advantages and disadvantages. MRI is mainly used to check whether the brain tissue structure is normal, for example, to see whether the patient has brain infarction, brain tumor or cerebrovascular lesions. The EEG is a functional test that detects the patient’s brain waves and is mainly used for various intracranial infections and various types of epilepsy. Patients with epilepsy need both an EEG to see abnormal neuronal discharges and an MRI to clarify the specific lesion, so in many cases the two are complementary.
