About The Test
Definition & Purpose
- MRI Temporal Bones is a high-resolution magnetic resonance study focused on the temporal bone, inner ear, and surrounding nerves.
- It shows nerves, blood vessels, and soft tissue far better than traditional imaging.
How It Differs from CT & X-ray
| Imaging Type | Radiation | Best For |
|---|---|---|
| X-ray | Yes | Quick fracture check |
| CT | Yes | Bone detail |
| MRI Temporal Bones | Zero | Nerves, tumors, infection |
List of Parameters
- Cochlear nerve integrity and diameter
- Vestibular apparatus and semicircular canals
- Facial nerve canal, labyrinthine segment & tympanic segment
- Middle ear cavity, ossicles (malleus, incus, stapes)
- Mastoid air cells for fluid or inflammation
Why This Test
- Unexplained sensorineural hearing loss
- Recurrent vertigo or imbalance unresponsive to medication
- Suspected acoustic neuroma or schwannoma pressing on nerves
When to Take Test
Benefits
Benefits of a Temporal Bone MRI Test
- Zero radiation – safe for children and repeated follow-ups
- Superior soft-tissue contrast – finds 1–2 mm lesions earlier
- Early detection leads to better outcomes and hearing preservation
Conditions Diagnosed with an MRI of Temporal Bone Radiology Scan
| Condition | What MRI Shows |
|---|---|
| Vestibular schwannoma | Enhancing mass in internal auditory canal |
| Cholesteatoma | Soft-tissue sac eroding bone |
| Otosclerosis | Abnormal spongy bone around cochlea |
| Congenital anomalies | Cochlear malformations, enlarged vestibular aqueduct |
Preparing for test
- Fasting: Not required for non-contrast; 4-hour fast if contrast is planned.
- Medications: Take all routine drugs with small sips of water.
- Metal screening: Remove jewellery, hearing aids, hairpins; inform staff about pacemakers, cochlear implants, or tattoos.
- Clothing: Wear metal-free cotton garments or change into our provided gown.
Pre-requisites
- Doctor’s prescription or referral note
- Previous imaging reports (CT, prior MRI) for comparison
- Recent renal function test (creatinine) if gadolinium contrast is needed
Best Time to Take the Scan
- Early morning slots reduce wait times and help claustrophobic patients feel calmer.
- Avoid acute ear infections; reschedule if you have active pain or discharge.
Eligibility
- Adults & children ≥5 years
- Pregnancy: 2nd or 3rd trimester only if essential; no contrast given
Step-by-Step Procedure
- Registration & safety screening (~10 min)
- Positioning: Lie on your back; head secured in a soft coil (~5 min)
- Scan: 25–35 min of intermittent loud knocking; earplugs provided
- Contrast injection (if ordered) via IV line during the scan
- Post-scan observation (~15 min) for any delayed reaction
Caution Before the Test
- List all implants: joint replacements, stents, IUDs
- Report tattoos with metallic ink; may warm up
- Ask about sedation if you have severe claustrophobia
Test Results
Results and Interpretations
| Finding / Observation | Description | General Interpretation/Significance |
|---|---|---|
| Cochlear nerve | Uniform thickness, no enhancement | Enhancement suggests neuritis or tumor |
| Vestibular system | Symmetrical fluid signal | Loss of signal indicates labyrinthitis |
| Middle ear cavity | Air-filled, ossicles intact | Fluid or mass suggests infection or cholesteatoma |
| Enhancing mass | Bright lesion in canal | Acoustic neuroma |
| Fluid in mastoid | High signal on T2 | Otitis media with effusion |
| Cochlear malformation | Incomplete turns | Congenital hearing loss |
Risks & Limitations
| Risk | How We Handle It |
|---|---|
| Pacemaker / Implant | Step-by-step metal screening before entry |
| Claustrophobia | Open-bore MRI & optional mild sedation |
| Missed bony detail | If bone erosion is suspected, we may recommend a follow-up CT |
FAQs
Is MRI Temporal Bones safe for kids?
Yes. The scan uses no radiation, and our technologists are trained in paediatric sedation and distraction techniques.
How soon will I get results?
Most reports are available the same evening. Critical findings are phoned to your doctor within 30 minutes.
Do I need contrast every time?
No. A non-contrast scan is often enough. Contrast is added only when infection, tumor, or nerve inflammation is suspected.
Can I drive after the scan?
Yes, unless you received sedation. In that case, arrange a companion for 4–6 hours.
What if I'm claustrophobic?
We offer an open-bore MRI, music headphones, and mild oral sedation on request.
Are there any side effects from the MRI scan?
MRI is considered very safe with no known long-term side effects. The most common issues are related to claustrophobia or, very rarely, a mild allergic reaction to the contrast agent. Our team at Cadabam's Diagnostics is fully prepared to manage any such concerns.
