MRI as a single screening procedure for acoustic neuroma: a cost effective protocol.

摘要: Abstract Magnetic resonance imaging (MRI) is accepted as the 'gold standard' in diagnosing acoustic neuromas. Limited availability and perceived high costs have prevented clinicians from using it a first-line investigation. A prospective study was set up specially designated screening session to audit cost effectiveness accuracy of audiovestibular investigations compared MRI. Ninety-nine patients with asymmetrical symptoms or signs were investigated. Of these 54 evoked response audiometry tests, 39 calorics either not performed inconclusive. One patient refused enter MRI machine. All others received an unequivocal report after four tumours (three intracanalicular) detected. The total protocol 12,545 pounds 12,900 for protocol, which diagnostic well-tolerated procedure. This shows that can be effective, well accurate, when used single procedure
