Radiology nursing is the care of patients undergoing imaging and image-guided procedures. It is small, largely invisible from the rest of the hospital, and has grown steadily as interventional radiology has taken over procedures that used to require an operating room.
Where the nurse fits
Imaging departments employ nurses for the parts of the work that are clinical rather than technical. The technologist runs the scanner; the nurse manages the patient.
Interventional radiology. Angioplasty and stenting, embolization, thrombectomy, biopsy, drain and catheter placement, tumour ablation, and vascular access. Nursing here is procedural: sedation, monitoring, haemodynamics, and access site management, with recovery afterwards. It closely resembles perioperative and post-anesthesia practice.
Computed tomography and magnetic resonance imaging. Contrast administration and reaction management, sedation for patients who cannot hold still, and care of unstable inpatients who must leave their unit to be scanned.
Neurointerventional procedures, including stroke thrombectomy, where the nurse is part of a time-critical pathway. See neuroscience nursing.
Nuclear medicine and radiation oncology, where radiation safety and patient preparation dominate.
The three risks
Sedation. Much of the specialty's work involves moderate sedation given by a nurse under a physician's direction, with the same requirements as anywhere else: documented competency, continuous monitoring, reversal agents and airway equipment immediately available, and a hard boundary at deep sedation. State boards differ on what a registered nurse may give, which matters when moving states. See scope of practice.
Contrast media. Iodinated and gadolinium-based agents cause reactions ranging from mild to anaphylactic, and the nurse is the person who screens for risk, recognizes the reaction, and treats it. Renal function, prior reactions, and specific medications all change the plan.
Radiation. This is the specialty's occupational hazard rather than a patient one. Nurses working in interventional suites accumulate scatter dose over a career, wear lead for long procedures, and are monitored by dosimeter. Lead aprons are also a documented source of orthopaedic injury among staff who wear them daily.
Magnetic resonance imaging adds a hazard of its own, which is that the magnet is always on. Every item and every implant entering the room has to be screened, and the consequences of failure are severe.
Certification
The credential is CRN, awarded by the Radiologic Nursing Certification Board, which is separate from the specialty's professional association. The examination is offered monthly.
Nurses in interventional suites commonly hold critical care or emergency certification as well, and moderate sedation and advanced cardiac life support competencies are effectively required.
Getting in and staying
Radiology nursing recruits from critical care, emergency, and post-anesthesia backgrounds, because the specialty assumes airway and haemodynamic skill on day one.
The attractions are a largely scheduled workload, an intellectually varied procedural practice, and — outside interventional call rotas — hours that are unusually predictable for a procedural area. Interventional radiology takes overnight call for stroke and bleeding emergencies, which is the main exception.
