“…6 In another study, several of the clinicians referred over 70% of new patients with audiovestibular symptoms for MRI. 2 Also, British Association of Otorhinolaryngologists reported that imaging evaluation comprised 10% of the MRI workload in hospitals with sizeable otolaryngology departments. 6 It has been documented that the diagnostic outcome of MRI screening for audiovestibular symptoms does not compare with that of other situations as for example MRI screening of children with epilepsy, where 12.7% of cases have relevant positive imaging findings.…”

“…9 According to Vanderveldea and Connor, MRI is "specifically focused on excluding treatable compressive abnormality of the cerebellopontine angle as a rare cause of audiovestibular dysfunction". 2 Referral of patients with audiovestibular symptoms for MRI is a relatively frequent practice at out institution. Its cost-effectiveness was a point of discussion; therefore we conducted this study to investigate the cost-effectiveness of MRI for evaluating patients with audiovestibular symptoms at out setting.…”

“…Additionally, there are several reports investigated the diagnostic accuracy and diagnostic yield of MRI for the assessment of audiovestibular dysfunction. 2 Several studies have been considered MRI as an appropriate, low-cost and rapid screening test for audiovestibular dysfunction. [12][13][14][15][16][17] although its ability to confidently detect small lesions has been questioned.…”

“…6 Therefore, it is important to reassess the diagnostic yield of MRI in the evaluating patients with audiovestibular symptoms compared to previous studies, and to determine whether presenting clinical features could be used to predict a positive imaging study and hence guide future referral protocols. 2,7,8 This retrospective study is therefore being carried out to investigate cost-effectiveness of MRI for evaluating patients with audiovestibular symptoms. This study being unique of its kind in the kingdom will help to formulate a proper protocol for such patients presenting with audio-vestibular disease and identifying them correctly for being a candidate for MRI scanning thus indirectly reducing the work load and cost to the hospital.…”

“…1 However, not all cases of asymmetrical sensorineural hearing loss (SNHL) have retro-cochlear pathology and till date debate still exists among researchers regarding the use of MRI in all the cases presenting as asymmetrical SNHL. [1][2][3][4] MRI as an expensive imaging technique should have an effective utilization strategies to minimize the rising imaging-related health care costs. 4,5 The MRI referral rates by general practitioners are increasing to audiology departments, which may have a significant impact on service provision.…”

Background: Till date, debate still exists among researchers regarding the use of magnetic resonance imaging (MRI) in all the cases presenting as asymmetrical sensorineural hearing loss (SNHL). The objective of the study was to investigate cost-effectiveness of MRI for evaluating patients with audiovestibular symptoms. Methods: A retrospective study was carried out included all adult patients (>12 years) presenting over a 12 month period between November 2014 and October 2015 at Otolaryngology department clinic, Armed Forces Hospital. Khamis Mushait, Saudi Arabia with asymmetrical sensorineural hearing loss (sudden or progressive) and have underwent MRI of cerebellopontine angle and internal auditory meati for evaluation of audiovestibular symptoms. Results: The study included 52 patients with audiovestibular symptoms. Their mean age (±SD) was 46 (±13.9) years and almost two-thirds of them (65.4%) were males. Majority of them were presented with deafness (84.6%). Vertigo and tinnitus were presented in 38.5% and 53.8% of them, respectively. Over the studied 52 patients, MRI of cerebellopontine angle yielded no detectable lesion in any case. Conclusions: MRI was not cost-effective, so it is important that clinical and audiometric indications for MRI referral criteria should be reviewed and analyzed to ensure cost-effectiveness of MRI in detecting audiovestibular dysfunctions, particularly in situations with financial restraints and long waiting time.

Magnetic resonance imaging (MRI) is the imaging method of choice for patients with vestibular schwannoma, with almost 100 % sensitivity and specificity. The role of computed tomography (CT) is limited to preoperative planning and the postoperative phase. High-resolution sequences and the application of gadolinium-based i.v. contrast medium are crucial for MRI-based diagnosis. Description of the size and location of the tumor, as well as its relationship to adjacent structures and anatomic features, is essential, since these factors, in addition to clinical findings, influence the type of treatment, surgical options, and associated risks. A postoperative linear contrast enhancement is often seen for up to 6 months and sometimes even longer. However, if this is of nodular structure, a recurrent schwannoma is likely. A sufficient statement regarding tumor response is not possible within the first 24 months after stereotactic radiosurgery. An increasing tumor volume after 24 months indicates failure of the treatment. Knowledge of the features of vestibular schwannomas allows all other possible differential diagnoses to be confidently excluded.
