No. You’ll feel only the table moving and hear knocking sounds.

How soon will I get results?

Plain scan: same evening. Contrast scan: next working day.

Can I eat before MRI Brain + PNS?

Yes, unless contrast is ordered—then 4-hour fast.

What if I’m claustrophobic?

Ask for open MRI or mild sedation; our technicians coach breathing techniques.

Is contrast dye safe?

Gadolinium is generally safe; we screen kidney function first.

What are the next steps after my scan?

Your referring doctor will receive the detailed report from the MRI BRAIN + PNS scan. They will then review these findings in conjunction with your symptoms and medical history to make a diagnosis, discuss any further investigations if needed, and outline potential treatment or follow-up plans with you.

MRI Brain + PNS Overview

Definition

MRI Brain + PNS combines a brain MRI with paranasal sinus imaging to create detailed 3-D pictures of:

Brain parenchyma, ventricles, vessels
Frontal, maxillary, ethmoid & sphenoid sinuses
Nasal cavity, septum, turbinates, orbits and skull base

How It Differs From Stand-Alone Scans

Feature	MRI Brain Only	MRI PNS Only	MRI Brain + PNS
Area Covered	Brain	Sinuses	Both in one scan
Scan Time	~20 min	~20 min	25–35 min
Cost	One study	One study	One combined fee

Technology Used

1.5T & 3T closed MRI for highest detail
Open MRI option for claustrophobic or bariatric patients
Advanced software reconstructs both regions simultaneously

List of Parameters

List of Parameters Considered During MRI Brain + PNS

Brain: grey & white matter, ventricles, vessels, pituitary
Sinuses: mucosal thickening, polyps, mucoceles, air-fluid levels
Nasal cavity: septal deviation, turbinate hypertrophy
Orbits & skull base: masses, bony erosion, CSF leaks

When to Take Test

Chronic sinusitis with suspected complications Suspected brain tumour extending into nasal cavity or sinuses CSF rhinorrhoea (nose leak) evaluation Pre-surgical ENT mapping for endoscopic sinus surgery Unexplained facial numbness or swelling Recurrent epistaxis (nosebleeds) of unknown cause Post-traumatic skull-base fracture assessment

Benefits

Benefits of Taking the test

Single session – saves time and cost
No radiation – safe for children & repeat follow-ups
Superior soft-tissue contrast – detects lesions CT may miss
3-D reconstruction – aids surgeons in navigation

Illnesses Diagnosed with MRI Brain + PNS

Illness	What the Scan Shows
Acute or chronic sinusitis	Mucosal thickening, air-fluid levels
Nasal polyps	Soft-tissue masses in sinuses or nasal passage
Brain tumours	Mass effect, enhancement with contrast
Mucoceles / cysts	Expanded sinus cavity with fluid signal
Meningoencephalocele	Brain tissue herniation into sinuses
Vascular anomalies	Aneurysms, AVM near skull base

Preparing for Test

Preparing for MRI Brain + PNS

Fasting: 4 hours only if contrast is ordered. Plain scans—no fasting required.
Metal objects: Remove jewellery, hairpins, piercings; credit cards stay outside.
Clothing: Change to MRI-safe gown; zippers & buttons interfere.
Medical history: Inform staff of pregnancy, kidney disease, prior contrast allergy.

Pre-Requisites

Creatinine report (within 4 weeks) if contrast scan is booked
Previous imaging discs (CT/MRI) for accurate comparison
Signed consent after safety questionnaire

Best Time to Take the Test

Morning slots reduce anxiety and claustrophobia fatigue
Avoid during active nasal bleeding or severe cold (may degrade images)
Children: schedule when they’re most cooperative (early morning or post-nap)

Eligibility

Group	Eligibility
Adults	Any age
Children	>5 years (younger kids may need sedation)
Pregnancy	Only if medically essential; no contrast in 1st trimester

Step-by-Step Procedure

Arrival & registration – 10 min
Safety screening & IV line if contrast – 15 min
Positioning on table with head coil – 5 min
Scan acquisition – 25–35 min (sequences: T1, T2, FLAIR, DWI, sinus STIR)
Contrast injection (if ordered) – 2 min via power injector
Post-scan observation – 15 min for contrast reactions
Discharge with receipt & online report link

Cautions Before the Test

Contrast allergy: Premedication available if prior reaction documented
Sedation: Oral or IV mild sedation arranged for anxious patients
Children: Child-life specialist distracts with video goggles or music

Risks & Limitations of MRI Brain + PNS

Risk / Limitation	How We Manage at Cadabams Diagnostics
MRI-incompatible implants (pacemaker, cochlear)	Pre-scan safety checklist & radiologist review
Claustrophobia	Open MRI, music headphones, mild sedation if needed
Motion artefacts	3T fast sequences reduce scan time
Cost vs CT	Transparent pricing; CT reserved when bone detail is priority

Test Results

Results and Interpretations

Finding / Observation Area	Description of Potential Findings	General Interpretation / Significance Example
Mucosal thickening	>4 mm sinus lining	Chronic sinusitis
T2 bright mass	Polyp / mucocele	May need surgery
Enhancing lesion	Gadolinium uptake	Tumour or infection
CSF signal in sinus	High T2 fluid	Possible CSF leak
Deviation	Septum shifted >50 %	Surgical candidacy
Blood Vessels (if MRA performed)	Normal arterial anatomy; findings may include stenosis, occlusion, aneurysm, vascular malformations (AVM), or dissections	Normal vessels, or may indicate stroke risk (stenosis/occlusion), aneurysm (rupture risk), or AVMs that require close monitoring or intervention.
Incidental Findings	Any findings not related to the primary indication for the scan, such as cysts, benign tumors, degenerative changes, or congenital anomalies	Often clinically insignificant, but may warrant further follow-up. Examples: arachnoid cysts, old infarcts, tiny meningiomas, or cervical spine degenerative disease.
