Interventional Radiology

What is Interventional Radiology and Interventional Neuroradiology?

Interventional Radiology and Neuroradiology offers a minimally-invasive alternative to the surgical treatment of many conditions and in most cases also reduces the need for hospitalization.

Interventional radiologists treat an ever-increasing range of conditions by utilizing small instruments, such as catheters or wires, which are guided through the body by use of various x-ray and imaging techniques, such as CT, MRI, ultrasound, etc.
