About The Test
Quick Snapshot: What the Scan Does
- Purpose: Visualises the cochlea, vestibule, semi-circular canals, auditory nerve and surrounding bone structures.
- No contrast: Safer for patients with kidney issues or dye allergies.
- Duration: 25–35 minutes total appointment time.
Why Choose Cadabams Diagnostics
- 3T MRI scanners for sharper detail than standard 1.5T machines.
- Same-day digital reports sent to your phone and referring doctor.
- Comfort-first approach: Wide-bore design, music headphones and optional mild sedation.
List of Parameters
| Parameter | What We Check | Why It Matters |
|---|---|---|
| Cochlear nerve calibre | Thickness & signal | Rules out compression or tumour |
| Semi-circular canal integrity | Shape & fluid signal | Diagnoses BPPV or canal dehiscence |
| Middle ear ossicles | Malleus, incus, stapes | Detects erosion or fixation |
| Internal auditory canal (IAC) diameter | Width & symmetry | Early sign of acoustic neuroma |
Why This Test
- Unexplained hearing loss or tinnitus – identify tumours or malformations.
- Vertigo or balance disorders – visualise inner-ear fluid dynamics.
- Post-traumatic facial palsy – check for temporal bone fracture.
When to Take Test
Benefits
Opting for an MRI Bilateral Temporal Bone / Inner Ear Without Contrast at Cadabams Diagnostics offers several significant benefits in your diagnostic journey:
- Early detection of acoustic neuroma – improves treatment outcomes.
- Non-invasive and painless – no needles or radiation.
- Same-day digital reports – faster specialist consultation.
Illnesses Diagnosed with a Temporal Bone & Inner Ear MRI (Without Contrast)
- Acoustic neuroma / vestibular schwannoma – benign nerve-sheath tumour.
- Meniere’s disease – endolymphatic hydrops.
- Labyrinthitis – viral or bacterial inflammation.
- Cholesteatoma – cystic mass eroding bone.
Preparing for test
- Fasting not required – eat and drink normally.
- Remove all metallic objects – jewellery, hairpins, hearing aids.
- Inform about implants – pacemaker, aneurysm clips, or tattoos with metallic ink.
Pre-requisites
- Signed MRI safety checklist – completed on arrival.
- Recent audiometry report – bring if available; helps correlate findings.
Best Time to Take the MRI Bilateral Temporal Bone / Inner Ear Without Contrast
- Morning slots – shorter wait times and fresher staff.
- Book 24–48 h in advance – secure your preferred slot via our app or website.
Eligibility
- Adults and children over 5 years – paediatric sedation available.
- No renal function restrictions – no contrast means no GFR blood test needed.
Procedure for Taking a MRI Bilateral Temporal Bone / Inner Ear Without Contrast
- Check-in & safety screening (~10 min)
- Positioning in 3T scanner – lie on your back, head in a cushioned cradle (~30 min scan)
- Post-scan image QC & digital upload – radiologist reviews images immediately.
Caution Before Taking the Test
- Notify staff of pregnancy – especially first trimester.
- Claustrophobic patients – request mild oral sedation (requires accompanying adult).
Test Results
Inner Ear & Auditory Canal MRI Findings – Reference Table
| Finding/Observation Examples | General Description | Possible General Interpretation / Significance |
|---|---|---|
| Normal cochlear nerve | Uniform thickness, no mass | No tumour |
| Enlarged IAC | >8 mm diameter on one side | Possible acoustic neuroma |
| High signal in labyrinth | Bright on T2 | Labyrinthitis or hydrops |
| Ossicular erosion | Missing incus long process | Chronic otitis media or cholesteatoma |
| No Obvious Mass or Lesion | No visible tumors, significant inflammation, or structural abnormalities in the auditory pathway. | A reassuring finding. Persistent symptoms may require functional or neurological evaluation. |
| Asymmetry in Inner Ear Fluid Signal | One inner ear has different fluid signal characteristics compared to the other. | May suggest endolymphatic hydrops (e.g., Meniere’s disease) or labyrinthitis. Specialized imaging or further workup may be needed. |
Risks & Limitations
- No radiation risk – MRI uses magnetic fields, not X-rays.
- Limitations: Small inflammatory changes may be less visible than with contrast.
- Contraindications:
- Pacemakers or cochlear implants (unless MRI-conditional)
- Severe claustrophobia (we offer sedation)
- First-trimester pregnancy (discuss with radiologist)
FAQs
How long does the scan take?
About 25–35 minutes from arrival to departure.
Is the procedure noisy?
Yes, but we provide noise-cancelling headphones with music.
Can I drive home after?
Yes, unless you took sedation—then bring a companion.
When will I receive the report?
Digital report within 4–6 hours; printed copy on request.
What if I'm claustrophobic?
If you suffer from claustrophobia, please inform our staff when scheduling your appointment and when you arrive. We can discuss several options:
* Our technologists are experienced in helping anxious patients and can offer support and reassurance.
* You may be able to have a friend or family member (screened for MRI safety) in the room with you (depending on policy).
* Sometimes, mild sedation prescribed by your doctor can help you relax.
* In some cases, if available and appropriate for the required image quality, an Open MRI might be an alternative.
How much does an MRI of the temporal bone without contrast cost?
The cost of MRI temporal bone no contrast can vary depending on several factors, including your specific insurance coverage, the complexity of the scan, and geographic location. For detailed information on pricing, insurance coverage, and any potential out-of-pocket expenses for your MRI Bilateral Temporal Bone / Inner Ear Without Contrast at Cadabams Diagnostics, please contact our billing department or patient financial services. They will be happy to assist you.
What if the scan shows an abnormality?
