An IR nurse, or interventional radiology nurse, is a registered nurse who specializes in caring for patients undergoing minimally invasive, image-guided medical procedures. These procedures use real-time imaging like X-rays, ultrasound, or CT scans to guide tiny instruments through the body, often replacing the need for open surgery. The IR nurse manages patient care before, during, and after these procedures, handling everything from sedation monitoring to passing surgical instruments to the radiologist.
What IR Nurses Actually Do
An IR nurse’s responsibilities span three distinct phases of every procedure. Before anything begins, the nurse conducts a full patient assessment: reviewing medical history, checking lab results, evaluating physical and psychological status, and developing a care plan. This pre-procedure work is critical because many IR patients have complex conditions or take medications that could affect bleeding or sedation.
During the procedure itself, the IR nurse works directly alongside the interventional radiologist. This means preparing supply trays, passing guidewires and catheters, setting up and maintaining sterile equipment, and practicing strict sterile technique throughout. The nurse also serves as the dedicated monitor for the patient’s sedation. While the radiologist focuses on the imaging and the procedure, the nurse tracks level of consciousness, oxygen levels via pulse oximetry, blood pressure (at minimum every five minutes), and continuous heart rhythm. This split responsibility is a formal safety recommendation: the person monitoring sedation should not be the same person performing the procedure.
After the procedure wraps up, the IR nurse monitors recovery, watches for complications like bleeding or changes in circulation, documents all assessments, and educates the patient on what to expect at home. The role covers the full arc from intake to discharge.
Common Procedures in IR
The procedures IR nurses assist with are varied, but they share a common thread: using imaging to guide treatment through small incisions or needle punctures rather than large surgical openings. Common examples include:
- Biopsies: Using imaging to guide a needle to a specific spot in the body and extract a tissue sample for analysis. Fine-needle aspirations use very thin needles to collect cells, while core biopsies use slightly larger needles with a cutting mechanism to retrieve a small piece of tissue.
- Drainage procedures: Inserting a needle or catheter to drain abnormal fluid collections like abscesses or cysts. Image-guided drainage has largely replaced surgical intervention for these cases.
- Vascular procedures: Angiography (imaging blood vessels), angioplasty (opening narrowed vessels), and embolization (deliberately blocking a blood vessel to stop bleeding or cut off blood supply to a tumor).
- Line placements: Inserting ports, PICC lines, or other central venous access devices under image guidance.
Some of these procedures take 30 minutes, others several hours. The IR nurse needs to be prepared for both routine cases and emergencies that arise mid-procedure.
Radiation Safety on the Job
Working in an environment with live imaging means IR nurses face regular exposure to scatter radiation, making protective equipment a daily reality. Lead aprons are worn at all times during procedures, typically providing the equivalent of 0.5 mm of lead shielding, which blocks 90% or more of scatter radiation. Thyroid shields wrap around the neck to protect the thyroid gland, which is particularly sensitive to radiation.
IR staff also wear dosimeters, small badges that measure cumulative radiation exposure. The International Commission on Radiological Protection recommends wearing two: one under the lead apron and one at collar level above it. These are checked monthly to track personal dose and flag any concerning patterns. Pregnant staff members wear an additional dosimeter at the abdomen, under their protective garments, to estimate fetal exposure.
Background and Training
IR nurses start as registered nurses with either an associate’s or bachelor’s degree in nursing. There’s no single required pathway into the specialty, but employers strongly prefer candidates who already have experience in critical care, emergency, or medical-surgical nursing. This preference exists for practical reasons: IR patients can deteriorate quickly, sedation carries real risks, and the nurse needs to recognize complications and respond without hesitation.
Once working in the field, IR nurses can pursue the Certified Radiology Nurse (CRN) credential through the Radiologic Nursing Certification Board. Eligibility requires a current nursing license, membership in the Association for Radiologic and Imaging Nursing, and a minimum of 30 documented continuing education hours in radiology nursing. Those hours can come from in-service classes, grand rounds, academic coursework, or specialty continuing education programs. The certification involves passing an exam and is not strictly required to work in IR, but it signals expertise and can improve job prospects.
Salary and Demand
As of early 2026, the average hourly rate for an interventional radiology nurse in the United States is $44.47, which translates to roughly $92,000 annually for full-time work. Actual pay varies significantly by state, facility type, and experience level.
Demand for IR nurses is growing steadily. Advances in imaging technology keep expanding the range of procedures that can be done without open surgery, and patients and physicians alike increasingly prefer minimally invasive options when they’re available. That trend directly translates into more IR suites needing skilled nursing staff.
How IR Nursing Differs From Other Specialties
IR nursing sits at an unusual intersection. It borrows the procedural intensity of operating room nursing, the monitoring demands of critical care, and the technical environment of radiology. Unlike a floor nurse managing multiple patients over a shift, an IR nurse often focuses on one patient at a time through a complete procedure. Unlike a radiology tech, the IR nurse’s primary focus is the patient rather than the imaging equipment.
The pace can swing dramatically. A routine biopsy might be straightforward and predictable, while an emergency embolization to stop internal bleeding demands fast, high-stakes decision-making. Nurses who thrive in IR tend to enjoy variety, hands-on procedural work, and the kind of focused patient interaction that comes with guiding someone through a single high-stakes event rather than managing ongoing care over days or weeks.
