Selçuk Peker is a leading Turkish neurosurgeon specializing in the radiosurgical treatment of brain diseases using Gamma Knife technology. Since 1999, Dr. Selçuk Peker has personally treated more than 13,000 patients using the Gamma Knife method. This makes him one of the most experienced doctors in the world in this field. Gamma Knife is a non-invasive radiosurgical technique that allows for precise targeting of tumors and other pathological changes in the brain without incisions. Working with this equipment requires exceptional precision, high qualifications, and a deep understanding of neuroanatomy.
Prof. Dr. Selçuk Peker has unique experience working with five of the six generations of Gamma Knife devices: U, C, B, Perfexion. He currently uses the most advanced model, the Leksell Gamma Knife Icon. This device opens up new possibilities for high-precision treatment without head fixation using a frame. The system allows therapy to be carried out in several stages (fractionally), which is especially important when the lesions are located near vital structures of the brain.
Selcuk Peker became the first specialist in Turkey to use the Gamma Knife Icon. Under his leadership, the radiosurgery department at Koç University Hospital was recognized as a benchmark center, receiving reference status from Elekta. It was here that advanced methods of treating patients with brain tumors, arteriovenous malformations, trigeminal neuralgia, and functional disorders such as Parkinson’s disease began to be introduced.
To better understand who Selçuk Peker Kimdir is, it is worth learning more about his practical activities. One of the most notable cases in the doctor’s work was the treatment of a large meningioma located near the optic nerves. Thanks to the possibility of performing fractional radiosurgery on the Icon device, Dr. Selçuk Peker was able to avoid traditional surgery. He performed Gamma Knife treatment in several sessions, achieving tumor stabilization without loss of vision in the patient and without damage to surrounding tissues. This intervention is an example of how modern technology and the doctor’s experience can minimize risks even in clinically complex situations.
In addition to his practical work, Selcuk Peker is actively involved in scientific research, publishes in international journals, speaks at specialized conferences, and is a member of European professional communities where he deals with issues related to the development of radiosurgery.
