What is Interventional Radiology (IR)?
Interventional radiology (IR) employs advanced imaging techniques to offer new treatment options for a wide range of conditions, allowing patients to undergo procedures with reduced risk and shorter hospital stays. IR can be applied to almost every organ system, and the list of conditions that can be diagnosed and treated with image-guided techniques is continuously growing. Body parts and systems treated using IR include:
- Abdomen: Intestine, kidneys, liver, stomach
- Central Nervous System: Brain, spine
- Chest: Lungs, respiratory system
- Heart and Vascular: Arteries, veins, hemodialysis access
- Musculoskeletal: Bones, joints, spine
- Genitourinary: Uterus, testes, kidneys
- Other Organs and Soft Tissues
Interventional radiologists provide comprehensive patient care, from initial evaluation and procedure information to post-procedural care. They can work independently or collaborate with other physicians to ensure the best patient outcomes.
Who is an Interventional Radiologist?
Interventional radiologists are doctors trained in radiology and minimally invasive procedures. They are experts in interpreting X-rays, ultrasounds, CT scans, and other imaging techniques. This expertise allows them to guide small catheters (tubes) and guidewires through blood vessels or other pathways to treat various diseases. These catheters are typically only a few millimeters in diameter.
Historically, interventional radiologists were primarily consultants for other specialists. However, patients can now be directly referred to them. For more information on direct referrals, please consult your doctor.
For many years, surgery was the only treatment option for numerous conditions. Consequently, many primary care physicians still refer patients to surgeons, who may not be fully informed about minimally invasive IR treatments. Therefore, it is crucial for patients to be aware of the options available through interventional radiology.
Benefits of Interventional Radiology
Interventional radiology offers several benefits:
- Accurate Diagnosis and Treatment: Cutting-edge imaging equipment allows for precise procedures.
- Minimally Invasive Procedures: Small skin nicks minimize discomfort and recovery time.
- Shorter Hospital Stays: Most procedures require only local anesthesia, allowing patients to go home the same day.
- Reduced Pain: Patients experience less pain during and after IR procedures compared to surgery.
- Post-Procedural Care: Follow-up imaging confirms the success of treatments.

Imaging Techniques in Interventional Radiology
- Angiography: Real-time X-rays of arteries or veins using contrast material to visualize blood vessels, guiding procedures like angioplasty and embolization.
- Computed Tomography (CT): X-ray imaging test providing detailed cross-sections of internal tissues, often used to create 3D images of blood vessels (CT angiogram).
- Fluoroscopy: Real-time moving X-ray images of internal structures, used for procedures like angiography and biopsies.
- Magnetic Resonance Angiography (MRA): Uses magnetic fields and radio waves to create images of arteries and veins, offering a non-invasive and radiation-free alternative.
- Ultrasound: Sound waves create 2D images of internal organs, commonly used for initial vascular assessments and guiding IR procedures like biopsies and ablations.
Interventional radiology continues to evolve, providing safer and more effective treatments for a growing number of conditions. If you are considering an IR procedure, consult with a specialist to explore your options.
