MRI Brain NPH Protocol Hyderabad | Focus Diagnostics

MRI Brain NPH Protocol Scan in Hyderabad

The MRI Brain NPH Protocol at Focus Diagnostics is a specialized neuro-imaging study designed specifically to evaluate patients suspected of having Normal Pressure Hydrocephalus (NPH). By combining high-resolution structural MRI with advanced Phase-Contrast Cine MRI (CSF flow study), this examination precisely measures ventricular enlargement, Evans' index, callosal angle, and cerebrospinal fluid (CSF) flow dynamics through the cerebral aqueduct, aiding in distinguishing reversible hydrocephalus from neurodegenerative conditions like Alzheimer’s or Parkinson’s disease.

Why Is an MRI Brain NPH Protocol Performed?

• Classic Hakim-Adams Triad Evaluation: Investigating patients presenting with the classic triad of gait disturbance (magnetic/shuffling walk), cognitive decline (mild dementia), and urinary urgency or incontinence.
• DESH Feature Detection: Identifying Disproportionately Enlarged Subarachnoid-space Hydrocephalus (DESH), characterized by tight high-convexity sulci and dilated Sylvian fissures.
• Ventriculomegaly & Evans' Index: Accurately calculating ventricular enlargement relative to overall intracranial diameter.
• CSF Flow Dynamics & Hyperdynamic Flow: Assessing CSF stroke volume and velocity across the Sylvian aqueduct using phase-contrast sequences.
• Surgical Shunt Candidacy: Determining whether a patient is a suitable candidate for ventriculoperitoneal (VP) shunt placement to reverse symptoms.

Key Benefits at Focus Diagnostics Hyderabad

• High-Precision Phase-Contrast Sequences: Accurate quantification of peak flow velocity and CSF stroke volume across the cardiac cycle.
• Advanced Volumetric & Morphometric Analysis: Detailed structural evaluation of callosal angle, periventricular white matter changes, and basal cisterns.
• Subspecialty Neuroradiology Expertise: Detailed reporting by experienced radiologists to support neurologists and neurosurgeons in surgical decision-making.

Patient Preparation and Important Instructions

• Fasting: Routine NPH protocols generally do not require fasting unless sedation or IV contrast is specifically requested by the physician.
• Comfort & Immobility: The scan requires resting flat and remaining completely still for accurate flow measurement sequences.
• Metal Screening: Remove all metallic objects, hearing aids, dental bridges, jewelry, hairpins, and watches before entering the MRI room.
• Implant Verification: Inform staff in advance if you have cardiac pacemakers, implanted pumps, aneurysm clips, or neurostimulators.
