Radiation technologies for brain & spine

Mayfield Clinic neurosurgeons use two different radiation technologies in the treatment of patients with primary or metastatic brain tumors, spinal tumors, and other neurological abnormalities, such as trigeminal neuralgia, arteriovenous malformations, cavernous angiomas, and chronic pain. Whether your radiation treatments are delivered by Gamma Knife® or TrueBeam™, your experienced Mayfield physician will provide you with world-class care.

Gamma Knife® uses precise, high-intensity gamma rays to target lesions. When a small tumor is being treated, a single dose of radiation is given in a single session using a rigid frame. When a large tumor is being treated, radiation is given in 5 treatments using a mask system.

TrueBeam™ enables precise, shaped-beam radiosurgery and radiotherapy of almost any tumor or abnormality. Using electron beam radiotherapy, TrueBeam can also treat tumors that are close to the surface of the body, including skin cancers. Patients are immobilized with a custom-made mask or body mold.

Mayfield provides Gamma Knife treatment at The Jewish Hospital - Mercy Health

Mayfield neurosurgeons based at The Jewish Hospital - Mercy Health use Gamma Knife to treat patients with benign, malignant, and metastatic brain tumors; trigeminal neuralgia; arteriovenous malformation (AVM); cavernoma; and essential tremor (in rare situations). No incision is made, and most patients are able to go home the same day. More than 30 years of clinical studies documented in more than 2,800 published medical papers have underscored the safety and effectiveness of Gamma Knife radiosurgery. Worldwide, more than 1 million patients have been treated with this method during the last 40 years.

Jordin's story

glioma brain tumor

One might say it was the storm before the calm. By the time Jordin had driven herself to Mercy Health – West Hospital, her head ached so badly that she could barely open her eyes. No, she did not have a history of headaches, she told the emergency room physician. No, the headaches during the last few weeks were not like anything she had ever experienced before.

 Multiple technologies, one high level of expertise

Although the technologies behind TrueBeam™ and Gamma Knife® differ, the objective of these "incisionless surgeries" is the same: to destroy a tumor or abnormality by bombarding it with precisely targeted beams of radiation while preserving healthy tissue.

Radiosurgery uses high doses of radiation in 1, 3 or 5 treatments, while radiotherapy uses lower doses of radiation given in as many as 30 to 35 treatments. Radiation works by damaging the DNA inside cells and making them unable to divide and reproduce, therefore causing them to die.

In both radiosurgery and radiotherapy, specialists use some of the same navigation tools of surgery, which allow the precise location of the lesion, or tumor. But instead of being removed with a knife, tumors are ablated with a machine: either a linear accelerator that delivers X-ray or electron beams or a Gamma Knife that delivers high-intensity gamma rays from a cobalt source.
