Non-Invasive Precision Radiation Treatment for Brain Tumors & Neurological Disorders
Radiosurgery is a highly precise, non-invasive form of radiation therapy used to treat brain tumors, vascular abnormalities, and certain neurological conditions without traditional surgery. Using focused radiation beams, radiosurgery targets abnormal tissue while minimizing damage to nearby healthy brain structures.
At Midwest Spine & Brain Institute, our experienced neurosurgeons and radiation oncology specialists provide advanced radiosurgery treatment planning for patients across Minnesota and Wisconsin using modern stereotactic technology and evidence-based care.
What Is Radiosurgery?
Radiosurgery, also called stereotactic radiosurgery (SRS), is an advanced radiation treatment designed to precisely target abnormalities in the brain or spine.
Despite the name, radiosurgery is not traditional surgery. No incision is made, and no tissue is physically removed. Instead, multiple highly focused radiation beams are directed at a tumor, vascular malformation, or nerve target to stop growth, shrink the lesion, or relieve symptoms.
The treatment is often completed in one session, although some patients may require several treatments depending on the condition being treated.
Conditions Treated with Radiosurgery
Radiosurgery may be recommended for both benign and malignant neurological conditions.
Commonly Treated Conditions Include:
- Brain tumors
- Metastatic brain tumors
- Acoustic neuromas
- Pituitary adenomas
- Meningiomas
- Arteriovenous malformations (AVMs)
- Trigeminal neuralgia
- Recurrent brain tumors
- Skull base tumors
- Certain spinal tumors

How Radiosurgery Works
Radiosurgery combines advanced imaging, computerized treatment planning, and highly targeted radiation delivery.
The Radiosurgery Process
1. Imaging & Evaluation
MRI, CT, or angiography scans are used to identify the exact treatment area.
2. Head Frame or Immobilization Placement
A specialized head frame or immobilization device helps keep the head stable during treatment to improve precision.
Local anesthetic is commonly used when placing a stereotactic head frame. Small sterile pins may be used to secure the frame and prevent movement during treatment.
3. Treatment Planning
Neurosurgeons and radiation oncologists work together to develop a customized treatment plan.
4. Radiation Delivery
Multiple focused radiation beams are directed at the abnormal tissue while minimizing exposure to surrounding healthy tissue.
5. Post-Treatment Monitoring
Patients are monitored after treatment and often return home the same day.
Types of Radiosurgery
Several radiosurgery technologies may be used depending on the patient’s diagnosis and treatment goals.
Gamma Knife Radiosurgery
Uses highly focused gamma radiation beams to treat brain lesions with exceptional precision.
LINAC-Based Radiosurgery
Uses high-energy X-ray beams delivered from multiple angles around the body.
Proton Beam Therapy
Uses proton particles that may help reduce radiation exposure to nearby healthy tissue in select cases.
Your treatment team will determine the most appropriate radiosurgery method based on your condition, lesion location, and overall health.
Symptoms That May Lead to Radiosurgery Evaluation
Patients may be evaluated for radiosurgery if they experience symptoms related to brain tumors or neurological disorders.
Common Symptoms Include:
- Persistent headaches
- Hearing loss
- Balance problems
- Facial pain
- Facial numbness
- Seizures
- Vision changes
- Weakness or numbness
- Hormonal imbalances
- Difficulty with coordination
- Neurological changes
Who Is a Candidate for Radiosurgery?
Radiosurgery may be appropriate for patients who:
- Have small-to-medium-sized brain tumors
- Need treatment near sensitive brain structures
- Are not ideal candidates for open surgery
- Have recurrent tumors after prior treatment
- Require minimally invasive treatment
- Have multiple brain metastases
- Need treatment for AVMs or trigeminal neuralgia
Every patient requires a comprehensive evaluation to determine the safest and most effective treatment plan.
Benefits of Radiosurgery
Radiosurgery offers several important advantages over traditional surgery for select patients.
Potential Benefits Include:
- No surgical incision
- No large scalp incision or stitches
- Minimal recovery time
- Outpatient treatment in many cases
- Reduced risk of infection
- Highly precise treatment targeting
- Protection of surrounding healthy brain tissue
- Effective treatment for difficult-to-reach lesions
Because radiosurgery is non-invasive, many patients recover faster compared to traditional brain surgery.
Risks and Potential Complications
Although radiosurgery is considered safe and effective, all medical procedures carry some risk.
Possible Risks Include:
- Fatigue
- Mild headache
- Temporary swelling
- Nausea
- Temporary neurological symptoms
- Radiation-related tissue changes
- Rare delayed complications
Your neurosurgeon and radiation oncologist will review the risks and benefits specific to your condition.
Recovery After Radiosurgery
Most patients recover quickly after radiosurgery.
Recovery Expectations
- Return home the same day in many cases
- Mild fatigue for several days
- Minimal activity restrictions
- Follow-up imaging to monitor treatment response
- Gradual improvement over weeks or months
Because no incision is involved, recovery is generally shorter than traditional neurosurgery.
Radiosurgery vs Traditional Brain Surgery
| Feature | Radiosurgery | Traditional Brain Surgery |
| Incision Required | No | Yes |
| Hospital Stay | Usually outpatient | Often several days |
| Recovery Time | Short | Longer |
| General Anesthesia | Often not required | Typically required |
| Physical Tissue Removal | No | Yes |
| Best For | Small targeted lesions | Large or complex masses |
Radiosurgery vs Conventional Radiation Therapy
| Feature | Radiosurgery | Conventional Radiation |
| Precision | Extremely high | Broader treatment area |
| Number of Treatments | Often 1–5 | Multiple sessions over weeks |
| Radiation Dose | Highly concentrated | Lower doses over time |
| Surrounding Tissue Exposure | Minimal | Greater exposure |
When to See a Specialist
You should seek evaluation from a neurosurgical specialist if you experience:
- Persistent neurological symptoms
- Newly diagnosed brain tumors
- Facial pain or numbness
- Seizures
- Balance or hearing problems
- Diagnosed AVMs
- Recurrent brain lesions
- Unexplained neurological symptoms
Early evaluation may improve treatment outcomes and expand treatment options.

What conditions can radiosurgery treat?
Radiosurgery can treat brain tumors, metastatic lesions, AVMs, acoustic neuromas, pituitary tumors, trigeminal neuralgia, and certain spinal tumors.
Is radiosurgery painful?
Most patients experience little or no pain during treatment. Mild discomfort may occur during head frame placement.
Why is a head frame used during radiosurgery?
A stereotactic head frame or immobilization system helps keep the head completely still to ensure highly accurate radiation delivery.
How long does radiosurgery take?
Treatment time varies depending on the condition being treated, but many procedures are completed within several hours.

Success rates vary by condition, but radiosurgery is highly effective for many tumors and vascular abnormalities.
Will I need follow-up imaging after radiosurgery?
Yes. MRI or CT scans are typically scheduled after treatment to monitor the treatment response and long-term outcomes.
Can radiosurgery replace open brain surgery?
In some cases, yes. However, certain large or complex tumors may still require traditional surgery.
