IG-SRT

Image-Guided Superficial Radiation Therapy (IG-SRT)

Biltmore Dermatology – Terre Haute & Vincennes

Not every skin cancer needs a scalpel. Image-guided Superficial Radiation Therapy (IG-SRT) offers a non-invasive, non-surgical treatment option for certain early-stage skin cancers. At Biltmore Dermatology, we use IG-SRT to provide safe, effective care without pain, needles, cutting, stitches, or surgical downtime.

What Is IG-SRT?

IG-SRT combines high-frequency ultrasound imaging with precisely targeted superficial radiation to treat skin cancers without surgery. The imaging allows us to:

• Map the exact size, shape, and depth of the skin cancer
• Target only the cancerous tissue
• Minimize exposure to surrounding healthy skin

The radiation is shallow and penetrates only the surface layers of the skin, making IG-SRT an ideal treatment for early-stage Basal Cell Carcinoma and squamous cell carcinoma.

Painless, Proven, and Precise

• Painless: Superficial radiation stays in the upper skin layers and does not reach pain-sensing nerves.
• Proven: FDA-cleared technology with decades of safe dermatologic use.
• Precise: High-frequency ultrasound maps the tumor so radiation targets only the cancer.

Benefits of IG-SRT

• Non-surgical
• No needles or anesthesia
• No cutting, stitches, or surgical wounds
• Painless treatment
• Excellent cosmetic preservation
• Outpatient appointments in Terre Haute and Vincennes
• Minimal downtime
• Cure rates comparable to surgical options in properly selected cases

IG-SRT offers a modern way to treat skin cancer without the scars that surgery can leave behind.

Who Is a Candidate for IG-SRT?

IG-SRT may be a strong option for patients with:

• Early-stage Basal Cell Carcinoma or Squamous Cell Carcinoma
• Lesions in cosmetically sensitive areas (face, ears, scalp, neck, hands)
• Medical conditions that make surgery risky
• A preference for non-surgical treatment

Not every case is appropriate, but for eligible skin cancers, IG-SRT provides a powerful, low-impact alternative.

What to Expect During IG-SRT

• Imaging first: A painless ultrasound maps the cancer
• Individualized planning: Depth and dose settings are customized
• Treatment sessions: Usually 2–4 times per week over several weeks
• Short appointments: Each visit lasts only a few minutes
• No sedation needed: You can drive yourself home
• Minimal side effects: Mild redness or dryness may occur

Imaging-guided planning ensures your care is delivered with precise settings tailored to your tumor.

IG-SRT Frequently Asked Questions

Is IG-SRT painful?

No. The radiation stays in the upper layers of the skin and does not reach pain-sensing nerves.

How long has IG-SRT been used?

Superficial radiation therapy has been used in dermatology for decades, and modern image-guided systems are FDA-cleared and widely adopted.

What skin cancers does IG-SRT treat?

Early-stage Basal Cell Carcinoma and Squamous Cell Carcinoma are both forms of non-melanoma skin cancer.

How is IG-SRT different from Mohs surgery?

Mohs surgery removes the cancer with a scalpel and creates a surgical wound that must heal. IG-SRT is non-surgical and uses imaging to precisely target only the tumor without creating a wound. Learn More

Does my insurance or Medicare cover IG-SRT?

Most major insurance plans — including Medicare — typically cover IG-SRT when it is medically necessary. Coverage varies by plan, and our office is happy to verify your benefits before treatment.
