Abstract: The main symptom of vertebrobasilar insufficiency (VBI) -transient ischemic focal neurological signs due to decreased blood supply to the vertebrobasilar resion- is vertigo, though vertigo without any other neurological signs (solo vertigo) is not enough to diagnose VBI. The etiological factors of VBI are the hemodynamic disorder like postural hypotension, cardiac arrythmia or blood hyperviscosity associated with athelosclerosis in arteries, usually in larger vessels of vertebrobasilar system or fibromuscular dysplasia, cardiac embolism, compression to vertebral arteries with bony deformity etc. It is very important to find out the patients who are in the stage of impending stroke and need antiplatelet therapy among those with solo vertigo. In this purpose, MR angiography is becoming to be a very useful non-invasive tool to verify the arterial stenosis or obstruction.
