Interventional Radiology is a department that treats patients by utilizing radiological imaging methods such as ultrasonography, angiography, tomography and less often magnetic resonance imaging as a guide. The interventions performed at this department are not surgical operations. On the other hand, most of these interventions used to be performed surgically in the past; interventional radiology renders it possible to perform them in non-surgical manner now. Unlike cardiology or ophthalmology, interventional radiology does not concentrate on a single organ or part of the body. It offers treatment options for the various regions of the entire body.

Interventional radiology treatments cover all vascular diseases of the body, aside from cardiac vessels. Treatment techniques performed for this purpose are clearance of vascular occlusions (balloon dilatation, stenting, stripping etc.) angiographic treatment of vascular aneurysms, stopping hemorrhages and embolization of hepatic tumors, myomas and conditions like prostate enlargement. 

Interventional radiology also carries out needle biopsies on all organs and tumors, abscess drainage and temporary or permanent treatment for bile duct and urinary tract occlusions. Treatment of some types of cancers, particularly those afflicting the liver, bones and lungs, are carried out at this department as well. Treatment of varicose leg veins and vascular anomalies (arterial or venous malformation) with or without angiography is another option available at this department. The common characteristic of interventional procedures is that each of them is performed through the tiny hole of a needle without requiring a surgical procedure. These interventions are performed under anesthesia and patients do not feel pain. They are mostly able to return home on the same day as the treatment. Equipment utilized is usually high-tech.
