Prof. Koray Güven, MD

Prof. Koray Güven, MD is a radiologist whose professional focus is interventional radiology. He practices in the Radiology unit of Acibadem Maslak Hospital in İstanbul, where he provides both diagnostic radiology and interventional radiology services. His work includes image-guided, minimally invasive procedures, among them transarterial radioembolization (TARE). Dr. Güven has worked in medicine for more than 27 years and holds the academic title of professor.

Dr. Güven graduated from Hacettepe University Faculty of Medicine in 1999. He then completed his specialty training in radiology at İstanbul University İstanbul Faculty of Medicine, finishing in 2004. He joined Acıbadem Healthcare Services in 2007 and has continued to work within the group since then, combining diagnostic imaging with interventional procedures as part of a hospital-based radiology team.

Clinical focus

Interventional radiology uses imaging guidance, such as ultrasound, CT or angiography, to carry out targeted procedures through small punctures rather than open surgery. The areas of expertise listed in Dr. Güven’s profile are interventional radiology in general and transarterial radioembolization (TARE) in particular. TARE is a catheter-based procedure in which small radioactive particles are delivered through the arteries that supply a tumor in the liver, with the aim of exposing the tumor to radiation from within while limiting exposure to surrounding tissue. Whether TARE or another interventional approach is appropriate depends on the individual patient, the type and extent of disease, liver function and any previous treatments. Such decisions are usually made together with the referring oncology or surgical teams rather than by the radiologist alone.

Case selection relies on current imaging. Cross-sectional and functional studies, which may include PET-CT imaging, are commonly reviewed as part of the work-up before an interventional procedure is planned, alongside laboratory results and the patient’s clinical history. In some cases additional imaging is requested before a final recommendation can be given.

How Dr. Güven works with international patients

Dr. Güven consults in Turkish and English, and interpreters can be arranged for patients who speak other languages. Before a visit, the Acibadem international patient team coordinates the collection of prior reports and imaging, for example MRI, CT, X-ray or ultrasound reports, laboratory and pathology results, operative notes and discharge summaries, and arranges appointments and the hospital visit. A first consultation typically covers the patient’s history and symptoms, a review of existing imaging and previous treatments, a clinical examination and a discussion of the options, including whether an interventional procedure appears suitable or whether further imaging is needed first. Video consultation is available for international patients who wish to discuss their situation or have their findings reviewed before deciding whether to travel to İstanbul.
