Interventional radiology, explained
What it is, how to prepare and how to recover.
Plain-language guides and videos from Dr. Fabio Komlos, for patients and families. Start with the basics, then read about your condition or procedure.

The basics
Interventional radiology in four ideas.
Imaging is the guide
X-ray, ultrasound and CT show us the inside of your body live, so we can reach the problem without opening it.
A pinhole, not an incision
Most treatments go through a puncture smaller than a pencil tip, in the wrist, groin or skin over the problem.
Usually home the same day
Most people go home the same day, with numbing medicine and sedation instead of general anesthesia.
Part of your care team
We work with your primary doctor, surgeon, oncologist, urologist or nephrologist, and keep them informed.
Guides for every procedure
Getting ready, sedation, blood thinners and recovery.
