Interventional Radiology (IR) is a minimally invasive medical specialty that uses image guidance—such as fluoroscopy, CT, ultrasound, and MRI—to diagnose and treat a wide range of conditions. IR procedures use needles, catheters, and guidewires to access the body without large incisions.
IR combines imaging expertise with procedural skill, offering alternatives to surgery with less pain, shorter recovery, and reduced risk.
IR uses real‑time imaging to guide instruments through blood vessels, organs, and soft tissues. Procedures are performed through tiny skin punctures rather than open surgery.
Common IR tools include catheters, guidewires, embolic agents, stents, balloons, and ablation probes.
IR plays a major role in oncology, vascular medicine, trauma care, women’s health, and pain management.

IR provides life‑saving and life‑improving treatments with minimal invasiveness. It is essential for managing bleeding, treating tumors, opening blocked vessels, draining infections, and delivering targeted therapies.
IR procedures often replace traditional surgery, reducing hospital stays and recovery times.
IR is also central to emergency medicine, providing rapid treatment for stroke, trauma, and internal bleeding.

IR facilities follow accreditation standards from the American College of Radiology (ACR) and the Joint Commission. These standards ensure proper equipment performance, radiation safety, and technologist competency.
Quality control includes fluoroscopy dose monitoring, equipment calibration, and sterile technique compliance.

Is IR minimally invasive? Yes. Most procedures use only a needle puncture.
What imaging is used? Fluoroscopy, CT, ultrasound, and MRI.
How long is recovery? Most patients go home the same day.

IR technologists require training in vascular anatomy, sterile technique, radiation safety, hemodynamics, and procedural assistance. Certification is available through ARRT and specialty IR pathways.
Students learn catheter skills, contrast administration, and emergency response.
