: If you had the hearing loss before the MRI in 2013 and 2014, you should not worry about retrocochlear pathology as the cause of your hearing loss. By UPTODATE: majority of patients with sudden sensorineural hearing loss likely have a viral, autoimmune, or microvascular etiology that cannot be diagnosed by any imaging study.
