Testing for Dizziness and Hearing
Most patients with dizziness that we see get an audiogram, a VHIT, and either a VENG or a rotatory chair test.
We offer most dizziness testing in the clinic. We may also reccomend additional procedures such as imaging, generally arranged for close to where patients live.
Tests for dizziness offered in the clinic
Neuroradiology tests (see also specific suggestions here)
- MRI/MRA of the head or neck (for a large number of structural disorders of the brain or it's blood
supply). Most MRI scans are done at the local hospital (NMH, Northwestern Memorial Hospital).
- 3T MRI (higher field) - These are very high resolution MRI scans, mainly suitable for cases where regular
MRI imaging has been insufficient. 3T MRI's are available at several hospitals in Chicago, including the hospital accross the street from us, Northwestern Memorial Hospital.
- CT scan of the temporal bone (for SCD or congenital deafness).
Usually done at NMH.
We strongly urge against having temporal-bone CT scans done at local hospitals. Even academic hospitals often
do a poor job with temporal bone CT scans.
Survey's offered on our online dizzy survey platform. We have done a lot of these (i.e. thousands)
Other tests are obtained in Northwestern Memorial Hospital, which is across the street from our practice.
In most instances, these tests need to be arranged for several weeks in advance.
Generally these tests are not routinely scheduled prior to the first visit but may be recommended after
