About The Test

Why Cadabams Diagnostics for epilepsy MRI

3T & 1.5T systems with epilepsy-dedicated coils
Radiologists trained in seizure protocol interpretation
Same-day appointments and online report access

Quick snapshot of test purpose and safety

Purpose: Pinpoint seizure focus and guide treatment
Safety: No radiation, non-invasive, safe for children and adults
Duration: 20–40 minutes, depending on sequences required

List of Parameters

Sequence	Slice Thickness	Gap	Purpose
T2 axial	4 mm	0.5 mm	General anatomy
FLAIR axial	4 mm	0.5 mm	White-matter lesions
DWI	4 mm	0 mm	Acute ischemia
T1 coronal	2 mm	0 mm	Hippocampal volume
T2 sagittal	4 mm	0.5 mm	Midline malformations

Why This Test

Identify mesial temporal sclerosis causing temporal-lobe epilepsy
Reveal cortical scarring from old trauma or infection
Detect low-grade tumours missed on CT scans
Spot vascular malformations such as cavernomas or AVMs
Guide anti-epileptic drug choices and surgical planning

When to Take Test

Common indications

First seizure after age 25
Intractable epilepsy (seizures despite two anti-epileptic drugs)
Pre-surgical work-up for epilepsy surgery or VNS implant

Adult vs paediatric eligibility

Adults: No age limit; safe even above 80 years
Paediatrics: From 1 month onward; child-friendly mock scanner available

Benefits

Benefits of Taking the Test

Non-invasive: No needles unless contrast is required
Radiation-free: Safe for children and repeated follow-ups
High-contrast images: Soft-tissue detail far superior to CT
Early diagnosis: Reduces seizure burden and long-term cognitive impact

Illnesses Diagnosed with MRI Brain Seizure Protocol

Epilepsy & seizure disorders
Hippocampal sclerosis
Brain tumours (low-grade gliomas, gangliogliomas)
Arteriovenous malformations (AVMs)
Cortical dysplasia, tuberous sclerosis, and other congenital malformations

Preparing for test

Fasting & medication guidelines

No fasting needed for routine protocol
Take anti-epileptic drugs as usual; bring list to appointment

Metal screening checklist

Remove jewellery, watches, hairpins
Inform staff about implants, tattoos, or prior eye injury

Best time to scan

Schedule when the patient is neurologically stable (no post-ictal confusion)

Eligibility criteria

Weight limit: up to 150 kg on 3T, 180 kg on 1.5T
Estimated GFR > 30 if contrast is planned

Step-by-step scanning procedure

Change into MRI-safe gown
Lie on table, head in epilepsy-dedicated coil
Foam cushions minimise motion
Earplugs and headphone music reduce noise

Cautions before entering MRI room

Lockers provided for mobiles, wallets, and keys
Credit cards and hearing aids must stay outside

Test Results

Results and Interpretations

Finding / Observation	Description	General Interpretation / Significance
Hippocampal sclerosis	Volume loss & T2 hyperintensity	Likely temporal-lobe epilepsy
Cortical dysplasia	Thickened cortex & blurred gray-white junction	May need surgery
Cavernoma	Popcorn-like lesion with hemosiderin rim	Risk of seizures
Low-Grade Glioma (e.g., Ganglioglioma)	Slow-growing brain tumor seen as abnormal mass with variable enhancement, often in temporal lobes.	May directly trigger seizures. Management typically includes neurosurgical consultation, biopsy, or resection, depending on tumor behavior.
Low-grade tumour	Hypointense T1, hyperintense T2	Biopsy or resection required
Gliosis / Encephalomalacia	Area of scarring or softening in the brain, appearing as volume loss with abnormal signal, often from prior injury.	Indicates previous brain injury (e.g., trauma, infection, infarct). This region may now act as a seizure focus.
Mesial Temporal Sclerosis (MTS)	A form of hippocampal sclerosis involving medial temporal lobe atrophy and signal abnormality.	Equivalent to hippocampal sclerosis; hallmark finding in many patients with temporal lobe epilepsy.
Evidence of Past Traumatic Brain Injury	Signs such as encephalomalacia, hemosiderin staining, or cortical irregularity reflecting previous trauma.	Post-traumatic epilepsy is common following significant brain injury. MRI findings help correlate with seizure onset zones.
Developmental Venous Anomaly (DVA)	A benign vascular anomaly with radial venous drainage pattern—typically normal brain tissue between veins.	Usually asymptomatic and incidental. Occasionally associated with seizure-causing cavernomas or other malformations.

Risks & Limitations

Contraindications

Cardiac pacemakers
Cochlear implants
Certain aneurysm clips and older ferromagnetic stents

Limitations in detecting subtle cortical dysplasias

Ultra-microscopic malformations may still be invisible
Post-surgical scar can mimic dysplasia—comparison with earlier scans helps

FAQs

How long does the scan take?

20–40 minutes, depending on whether contrast is used.

Is contrast dye always needed?

Only if a tumour or infection is suspected; most epilepsy scans are contrast-free.

Can children undergo this protocol?

Yes. We offer child-friendly mock sessions and sedation when necessary.

When will reports be ready?

Same day for urgent cases; routine reports within 24 hours.

Does it require hospitalisation?

No. It’s an outpatient procedure—you can go home immediately after.

Is the scan noisy or claustrophobic?

The machine makes knocking sounds; we provide earplugs and music. Our wide-bore 3T scanner reduces claustrophobia.
