About The Test
Introduction
MRI Brain with Navigation Protocol is a high-resolution imaging technique specifically designed to assist neurosurgeons in pre-operative planning and intraoperative navigation. This protocol provides detailed anatomical images of the brain that are compatible with neuronavigational systems used during surgeries for tumours, epilepsy, deep brain stimulation, and other neurosurgical procedures.
What is MRI Brain – Navigation Protocol
This is an advanced MRI scan using fine-cut, 3D isotropic sequences that allow multiplanar reconstructions and fusion with surgical navigation systems. It focuses on anatomical accuracy rather than functional or dynamic data, making it ideal for pre-surgical mapping.
List of Parameters
- High-resolution 3D T1-weighted images with or without contrast
- Multiplanar reconstructions
- Detailed visualisation of gyri, sulci, ventricles
- Registration compatibility with surgical navigation platforms such as Brainlab or StealthStation
Why This Test
- Pre-surgical anatomical mapping
- Guidance for accurate trajectory planning
- Integration with functional imaging or tractography
- Planning around critical brain structures
When and Who Needs MRI Brain Protocol?
Indications:
- Planning for brain tumour resection
- Epilepsy surgery
- Stereotactic biopsy
- Placement of deep brain stimulators
- Surgical planning in proximity to eloquent cortex such as motor, speech, or vision areas
Patient Demographics:
- Patients with brain tumours or metastases
- Epileptic patients undergoing surgery
- Neurosurgical patients requiring precise preoperative planning
- Candidates for awake craniotomy or functional surgery
Benefits
Benefits of MRI Brain Navigation Protocol
- High anatomical precision
- Essential for minimally invasive or complex brain surgeries
- Supports real-time neuronavigational during surgery
- Improves surgical outcomes and minimises damage to healthy tissue
Conditions Diagnosed by MRI Brain Protocol
- Gliomas, meningiomas, metastases
- Arteriovenous malformations
- Epilepsy pre-resection
- Deep-seated or eloquent cortex tumours
- Lesions near motor, speech, or visual areas
Preparing for test
- No fasting required
- Remove jewellery, hearing aids, and metal objects
- Inform about implants, pacemakers, or previous brain surgeries
- Patient may be marked with fiducials in some centres if required for surgical planning
Pre-requisites for MRI Brain Protocol
- Clinical referral from a neurosurgeon
- Prior diagnostic imaging for context
- Informed consent if contrast is needed
Best Time to Perform the MRI Brain Protocol
- Shortly before scheduled brain surgery
- Before functional mapping such as fMRI or DTI integration
- When neurosurgical planning or targeting is needed
Eligibility for MRI Brain Navigation Protocol
- All ages from older children to adults
- Patients scheduled for neurosurgical procedures
- Not ideal for those with MRI-incompatible implants
Procedure for MRI Brain with Navigation Protocol
- Patient lies still in the MRI scanner
- High-resolution 3D imaging performed
- Contrast may be given if lesion requires enhancement
- Data exported in compatible format for navigation systems
- Duration is approximately 30 to 45 minutes
Caution for MRI Brain Navigation Protocol
- Movement affects precision; immobilisation is essential
- Ensure compatibility with neuronavigational platform
- Repeat imaging may be needed if surgery is delayed or anatomy changes
Test Results
Results and Interpretations
Condition/Findings | Description | Interpretation |
---|---|---|
Tumour margins clearly defined | Accurate tumour boundary visualisation | Aids complete resection with minimal risk |
Relation to eloquent areas | Tumour near Broca’s or motor cortex | May guide awake surgery or resection limits |
Midline shift or mass effect | Displacement of normal anatomy | Alters surgical approach |
Contrast enhancement | Enhances lesion localisation | Confirms tumour vascularity or blood-brain barrier disruption |
FAQs
Is this a regular MRI scan
No, it is tailored with high-resolution 3D imaging specifically for surgical planning.
Is contrast always used
Not always. It depends on the lesion’s nature and the neurosurgeon’s preference.
Can it be used without surgery
It is mainly intended for pre-surgical planning and not routinely used for general diagnosis.
How does it help in surgery
It guides the neurosurgeon by providing a real-time map of brain anatomy during the operation.
