MRI-Guided Laser Ablation

St. John is the first hospital in northeastern Oklahoma to offer MRI-guided laser ablation for brain tumors as an alternative to the more traditional craniotomy. 

During this minimally invasive procedure, light energy is delivered to the target area using a small laser catheter.  As laser light is delivered, temperature in the target area begins to rise and is observed under real-time MRI imaging, allowing the surgeon precise control of the tissue ablation.


  • Minimally invasive – requires only a small incision
  • Shorter hospital stay – often just one day
  • Less cosmetic impact – little or no hair loss, small suture to close 

Patient testimonial

Dick Frierson never expected to need neurosurgery. When he did, he was thankful to have a compassionate team of doctors and nurses, along with cutting-edge neurosurgical technology available through St. John.
