MRI Brain Csf Flow Study

• Painless & Radiation-Free: No injections or X-rays
• Duration: 30–45 minutes total appointment time
• Cadabams Edge:
• 3T high-field MRI for razor-sharp images
• Fellowship-trained neuroradiologists reporting every scan

• Determine normal vs. obstructed CSF circulation
• Guide VP shunt placement or surgical decompression
• Monitor post-surgical CSF dynamics after Chiari repair or shunt revision
• Evaluate idiopathic intracranial hypertension

• Non-invasive – no injections or incisions
• Quantitative accuracy – precise velocity and volume data
• Early detection – prevents memory loss or walking difficulties
• Repeatable – safe for ongoing monitoring

• Communicating hydrocephalus – CSF reabsorption failure
• Non-communicating hydrocephalus – blockage within ventricles
• Chiari I / II malformation – abnormal cerebellar tonsil position
• CSF leaks – post-traumatic or spontaneous spinal fluid loss
• Intracranial hypotension – sagging brain due to low pressure

Pre-requisites

• Remove all metallic objects: jewelry, hairpins, belts
• Fasting: Not required; light meal allowed
• Best time: Any time of day; avoid caffeine if anxious

Eligibility

• Age: Adults and children ≥5 years
• Pregnancy: Discuss with radiologist in first trimester

Procedure Steps

1. Change into MRI-safe gown.
2. Lie on table; head in 12-channel brain coil.
3. Foam padding to keep head still.
4. 2–3 short scans (2–3 minutes each) + 5-minute CSF flow sequence.
5. Total table time: ~20 minutes.

Caution Checklist

• Inform staff of pacemaker, implants, claustrophobia, contrast allergies.

Safety Profile

• No radiation – safe for children and repeat scans
• No contrast dye required in most cases
• Claustrophobia: Open-bore 3T scanner reduces anxiety; music headsets available

Limitations

• Motion artefacts – slight head movement can blur images
• Contraindications: pacemakers, cochlear implants, certain aneurysm clips
• Pregnancy: first-trimester scans only when medically essential
