what imaging to order for vertigo
If the cause of your signs and symptoms is difficult to determine, your doctor may order additional testing, such as: 1  Electronystagmography (ENG) or videonystagmography (VNG). The purpose of these tests is to detect abnormal eye movement. 2  Magnetic resonance imaging (MRI). This test uses a magnetic field and radio waves to create cross-sectional images of your head and body. Your doctor can use these images to identify and diagnose a range of conditions. MRI may be performed to rule out other possible causes of vertigo.
