Minimally invasive treatments guided by imaging, less heavy, less expensive and less risky

Interventional radiology (IR) is a specialized branch of medical radiology focused on the use of advanced imaging to guide minimally invasive medical procedures.

This discipline allows physicians to perform a wide range of diagnostic and therapeutic interventions without the need for major open surgery. Using imaging techniques such as X-ray, ultrasound, CT scan or MRI, interventional radiologists can precisely visualize internal anatomy and guide medical instruments to targeted areas for treatments such as tumor ablation, vessel dilation, fluid drainage, or placement of medical devices.

This innovative approach has revolutionized many medical practices and offers significant advantages in terms of clinical outcomes and patient comfort.
