MRI scans

MRI inner ear (IAM)

A fine-slice scan of the internal auditory meatus and inner ear structures.

What to expect

  • Preparation: Usually none - eat, drink and take medication as normal unless told otherwise. You will complete a safety questionnaire covering implants and previous surgery, and remove all metal items before the scan.
  • During the test: You lie on a motorised couch that moves into the scanner. The machine is noisy, you wear ear protection, and you need to keep as still as possible. Most MRI examinations take 20-45 minutes.
  • Results: A consultant radiologist reports the scan, typically within 24-72 hours of your appointment.
  • Who follows up: The report goes to your referring GP or specialist, who explains the findings and arranges any follow-up.
  • Cost: an indicative cost varies by provider.

About this test

A fine-slice scan of the internal auditory meatus and inner ear structures. It is usually recommended for one-sided hearing loss, tinnitus or imbalance, chiefly to exclude an acoustic neuroma.

How to access it privately

You can arrange a private MRI either with a referral from your GP or specialist or, for many scans, by self-referring as a self-pay patient with a short pre-scan questionnaire. Routine NHS diagnostic waits are often long - frequently measured in months - whereas private slots are typically available within days to around two weeks. Costs vary by provider and should be confirmed with the provider before booking.

Frequently asked

Common questions about MRI inner ear (IAM).

Quick, plain-English answers to what people ask us most.

  • What is an MRI of the inner ear (IAM) and what does it show?

    This scan focuses on the internal auditory meatus (IAM) and inner ear, the small canal and structures that house the hearing and balance nerves. It's particularly good at detecting small nerve tumours and other causes of hearing or balance symptoms in this area.

  • Why would a doctor order this scan?

    It's commonly used to investigate one-sided hearing loss, persistent tinnitus, or balance problems where a nerve tumour called an acoustic neuroma (vestibular schwannoma) needs to be ruled out. It's also used to monitor known small tumours over time.

  • Do I need to prepare for the scan?

    There's usually no special preparation needed. Contrast dye is often used for this scan, so mention any allergies or kidney problems when booking, along with any implants such as cochlear devices.

  • What happens during the scan?

    You lie still with your head positioned in a coil, and the scan typically takes around 30 to 45 minutes given the fine detail required for this small area. A contrast injection is usually given partway through.

  • Does it hurt, and are there any risks?

    The scan is painless and doesn't use radiation. Contrast dye is generally well tolerated, with only a small risk of an allergic reaction.

  • How long do results take?

    A radiologist experienced in this type of imaging reviews the scan, with private results typically available within a few days. Your ENT specialist will then discuss the findings with you.

  • What do abnormal results mean?

    A small tumour on the hearing or balance nerve is one possible finding, and many of these are slow-growing and can simply be monitored rather than treated immediately. Your specialist will explain the size, likely behaviour and recommended next steps based on your specific scan.

  • How much does a private inner ear MRI cost, and is it available on the NHS?

    This scan is available on the NHS, typically via an ENT referral, though waiting times vary. Privately, scans are usually available within days with specialist reporting; cost varies by provider.

  • Is this scan accurate and reliable?

    MRI is highly sensitive for detecting even small abnormalities in the inner ear and hearing nerve, making it the standard test when this area needs to be assessed. Results are best interpreted by a radiologist experienced in this specific type of imaging.

  • How do I book a private inner ear MRI, and how quickly can I be seen?

    Private imaging centres can usually offer an appointment within a week. Contact a provider directly, ideally noting your specific symptoms, to check availability.
