Which is more accurate, MRI or CT, cannot be generalized, and the ENT doctor should choose the appropriate test according to the patient’s condition. MRI of the ear is stronger in showing the soft tissue structure and identifying its components, and can diagnose small ear lesions at an early stage. For example, bulbous tumor of the tympanic chamber, facial nerve tumor and so on. In-depth diagnosis can be made for complications of otitis media synostosis and congenital ear deformities. CT examination can show bony structures, which can show some middle ear lesions and bony developmental abnormalities of the inner ear. There are also tympanic body tumors, jugular vein globe tumors, and sigmoid sinus diverticula, which can be detected on CT examination. It is recommended that patients choose the appropriate examination under the guidance of the doctor, so as not to affect the diagnosis and treatment of the patient’s condition.
