At Jaslok Hospital in Dr. Paresh Doshi’s Functional Neurosurgery department, we offer advanced MRgFUS treatment in Mumbai, a non-invasive procedure for essential tremor and tremor-dominant Parkinson’s disease. While MRgFUS is highly effective for select patients, Deep Brain Stimulation (DBS) remains the gold standard for long-term symptom control, bilateral treatment, and flexible adjustment.
MRgFUS Continues to Expand as a Proven Incisionless Treatment
Magnetic Resonance-guided Focused Ultrasound (MRgFUS) is now widely recognized as an effective incision-free treatment for carefully selected patients with medication-resistant Essential Tremor and tremor-dominant Parkinson’s disease. Ongoing clinical evidence continues to demonstrate durable tremor control with a favorable safety profile.
Long-Term Safety Data Remains Reassuring
Recent long-term studies involving thousands of MRgFUS procedures have shown that most treatment-related side effects—such as temporary numbness, imbalance, or headache—improve over time. Importantly, no new long-term cognitive safety concerns have been identified in appropriately selected patients.
What is MRgFUS?
sMagnetic Resonance-Guided Focused Ultrasound (MRgFUS) is a cutting-edge, non-invasive neurosurgical procedure that uses focused ultrasound waves combined with real-time MRI guidance to target brain areas responsible for tremors.
- Non-invasive and scar-free
- Performed under MRI guidance for maximum precision
- Reduces tremors immediately, often during the procedure
Outpatient procedure with minimal recovery
How MRgFUS Works
- Comprehensive assessment – MRI and neurological evaluation.
- Precise targeting – MRI identifies the exact brain region causing tremors.
- Focused ultrasound delivery – Controlled energy ablates the targeted tissue.
- Real-time monitoring – MRI thermometry ensures safety.
Immediate results – Many patients notice tremor improvement during or right after the procedure.
Benefits of MRgFUS
- Non-invasive – No cuts, no implants
- Quick recovery – Most patients return home the same day
- Immediate results – Tremor reduction visible during treatment
Precision targeting – Protects surrounding brain tissue
Limitations of MRgFUS
While effective, MRgFUS has limitations compared to DBS:
- Unilateral treatment only – Only one side of the brain can be treated safely
- Permanent and irreversible – Cannot be adjusted or modified later
Limited flexibility – Less suitable for progressive or severe disease
MRgFUS Is Not Suitable for Every Movement Disorder
While MRgFUS provides excellent tremor relief for many patients, it is not the ideal treatment for everyone. Individuals with significant rigidity, dyskinesia, advanced Parkinson’s disease, or symptoms affecting both sides of the body may benefit more from treatments such as Deep Brain Stimulation (DBS) after specialist evaluation.
MRgFUS vs Deep Brain Stimulation (DBS)
Feature | MRgFUS | Deep Brain Stimulation (DBS) |
Procedure | Non-invasive, incision-free | Minimally invasive, electrode-based |
Reversibility | Irreversible | Fully reversible and adjustable |
Treatment sides | One side only | Can treat both sides safely |
Long-term control | Fixed results | Adjustable for disease progression |
Customization | None | Fine-tune stimulation anytime |
Ideal for | Mild tremor, patients unfit for surgery | Moderate to severe Parkinson’s, dystonia, essential tremor, complex cases |
Durability | May plateau over time | Long-term symptom control and quality of life |
MRI compatibility | Full MRI access | MRI-conditional systems available |
Insight: MRgFUS is suitable for select patients, but DBS provides superior long-term results, adjustability, and flexibility — making it the preferred choice for most movement disorders.
Who is a Candidate for MRgFUS?
MRgFUS is ideal for patients with:
- Essential Tremor (ET)
- Tremor-dominant Parkinson’s disease when medications fail
Eligibility requires:
- Detailed neurological evaluation
- MRI for precise targeting
- Assessment of overall health
Note: MRgFUS is best for unilateral, mild-to-moderate tremor, whereas DBS is preferred for bilateral or advanced symptoms.
Patient Selection Is Critical for Treatment Success
Before undergoing MRgFUS, patients undergo detailed neurological evaluation along with MRI and CT imaging. Factors such as the Skull Density Ratio (SDR), symptom severity, medical history, and treatment goals help determine whether a patient is a suitable candidate for the procedure
What to Expect During the Procedure
- Preparation – Blood tests, MRI scans, and pre-procedure assessment
- Procedure – Patient is awake; head stabilized; ultrasound energy delivered in phases
- Recovery – Typically outpatient; patients can resume normal activity within a day
Safety: Minor side effects like warmth, mild discomfort, numbness, or imbalance may occur but are usually temporary.
Recovery Is Usually Quick
Because MRgFUS is completely incisionless and does not require implanted hardware, most patients are able to return home within 24 hours. Many experience noticeable improvement in tremor immediately after treatment, although recovery varies depending on the individual and the underlying neurological condition.

1. What is MRgFUS treatment?
MRgFUS (Magnetic Resonance-guided Focused Ultrasound) is a non-invasive procedure that uses highly focused ultrasound waves guided by MRI to precisely treat specific brain areas responsible for tremors without making surgical incisions.
2. Which conditions can be treated with MRgFUS?
MRgFUS is commonly used for medication-resistant Essential Tremor and selected patients with tremor-dominant Parkinson’s disease. Suitability depends on an individual’s symptoms, medical history, and imaging findings.
3. Is MRgFUS better than Deep Brain Stimulation (DBS)?
Neither treatment is universally better. MRgFUS is incisionless and requires no implanted device, while DBS is adjustable, reversible, and often preferred for patients with bilateral symptoms or more advanced Parkinson’s disease. A movement disorder specialist can determine the most appropriate treatment.
4. Is MRgFUS a permanent cure?
No. MRgFUS does not cure Parkinson’s disease or Essential Tremor. It helps control tremors and improve quality of life but does not stop disease progression.
5. Who is eligible for MRgFUS?
Patients with disabling tremors that do not respond adequately to medications may be eligible. Eligibility is determined after neurological assessment, MRI, CT scan, and evaluation of skull density and overall health.
6. How long does MRgFUS treatment take?
The procedure generally takes 2 to 4 hours, including preparation, MRI guidance, treatment planning, and post-procedure observation.
7. What are the possible side effects of MRgFUS?
Temporary numbness, tingling, balance problems, headache, dizziness, or mild gait disturbances may occur after treatment. Most side effects improve over weeks to months, although a small number of patients may experience persistent symptoms.
8. How soon can patients return to normal activities after MRgFUS?
Most patients resume light daily activities within a few days after treatment. Recovery time varies depending on the individual’s condition and the treating neurologist’s recommendations.
